Scavenger Hunt

Bring a child to our celebration, take a little trip down memory lane, and catch glimpses of how much has changed on our grounds at 177 W. Hickory in Hesston as you observe the past and present. Review the following questions and find the corresponding laminated photos on placards at their respective locations on our grounds where you will find the answers.

What is the location of the first tree planted at the Arboretum? Hint: You’ll see it on the right as you exit the parking lot (watch for cars as you look!).

At 40+ years old now, this bur oak (Quercus macrocarpa) is turning into a stately tree.

What is the newest building at the Arboretum? (Hint: it is near the greenhouse.)

Our newest building – the Horticulture and Utility Building (HUB)

I won’t physically be at the celebration on Sunday as I will be attending a workshop in Wisconsin entitled Caring for Common Ground. It is being put on by the UW-Madison Arboretum authors of our Earth Partnership for Schools Program and Curriculum that we have been teaching to K-12 teachers and students in Kansas for the last 14 years. While you are celebrating the past and the present of Dyck Arboretum, not only will I be thinking of you, but I will also be dreaming about how future educational programming can continue to carry on Harold and Evie’s legacy for another 40 years to come.

Insects – Motivation for Native Landscaping

Early September blooming plants are attracting loads of nectar-sipping insects right now. Host plants are green and thriving from timely rains and providing food for munching larvae. All this insect activity has led to great enjoyment for me in exploring the Dyck Arboretum grounds and my home landscape. It has prompted me to think more about my real motivation for landscaping with native plants.

Plants or Insects?

For many years, I’ve claimed that my enjoyment of native landscaping was motivated by my love of plants. Indeed, their flowers, seed pods, seeds, seed dispersal mechanisms, and roots are all interesting traits and worthy of appeal. Getting to know their growth habits, moisture and light preferences all translate to the level of success I will have (or not) in establishing these plants in a given landscape. And early in their establishment, my focus is geared toward making sure they stay alive with my watering, mulching, and weeding efforts.

Common milkweed wind-blown seed dispersal mechanisms are cool to observe. But I am increasingly interested by the insects this plant attracts too (like the milkweed bug)

But as these long-lived perennials develop substantial root systems, become established, and begin to flower, I worry less about their survival. My perspective changes, turns towards what they can do for the local ecosystem. New questions arise. What insects are attracted to their flower nectar? Which insects are pollinating them and leading to seed production? What insect larvae are eating their leaves or other parts of the plant? What predators are in turn feeding on those insects?

Plants, being at the base of the food pyramid, dictate the level of diversity that exists further up the pyramid of consumption. Small bases lead to small pyramids and bigger bases lead to bigger pyramids. So in theory, the more different species of plants I install in my landscape, the more species of insects I will host. I can specifically predict what insects I will attract to a landscape based on the larval host plants I establish. For example, milkweed species will draw in monarch butterflies. Golden alexander or other species in the parsley family will draw in black swallowtail butterflies. Willow species will draw in viceroy butterflies, and so on. HERE is a list of butterfly larval host plants.

The Insects Have It

When I stop and think about it, the most interesting parts of tours at the Arboretum are when insects are visible and busy doing their thing. Stopping with a group to watch a hatch of caterpillars devour a plant leaf and dream of what those caterpillars will turn into is pretty cool. Observing a huddle of school kids dump out a sweep net and squeal with delight at finding the baby praying mantis, massive grasshopper, or whatever other interesting insect they are not used to seeing, simply makes my day.

Many of the species blooming now around the Visitor Center at Dyck Arboretum are sometimes considered invasive and perhaps even uninteresting because they are common. But as I highlight in another blog post Finding Value in the Undesirables, they attract a load of insects which makes them interesting to me. Here is a collection of photos of insects taken just outside my office last week:

One particular plant, Leavenworth eryngo (Eryngium leavenworthii), is stunning due to its vibrant color and interestingly shaped features. It’s often noticed by visitors walking to the greenhouse during FloraKansas: Fall Native Plant Days. However, what most people say when they see it is “did you see the swarms of insects on that plant?!” Customers are eager to recreate such insect habitat at their homes. For this reason, I keep a bag of seed for this annual species collected from the previous year to give away.

Become An Insect Promoter

This subtitle may make many traditional gardeners cringe. I have recently followed social media groups of gardeners where the anti-insect sentiment is rabid. Pesticides are commonly recommended to get rid of insect hatches in home landscapes and the recoil response related to spiders in general can be disturbing. Even many of our dedicated members that love to buy native plants for their landscapes don’t like to see the plants they come to love devoured by caterpillars. I am on a mission to change that.

So, if you are not already an entomology enthusiast and in awe of insects, I encourage you to take on a popular motivation for landscaping with native plants. Become more open to welcoming insects. Choose native plants or native cultivars not only because you think they will be pretty, but for how they will eventually host insects, enhance the food web they support, and increase the wildlife diversity in your landscape.

Seeded Prairie Checkup

I recently did a seeded prairie checkup to see how our December 2020 sidewalk planting described in the earlier blog post “Seeding After Disturbance” is doing. I’ve been informally monitoring it regularly since spring and have been encouraged by the progress I’ve seen.

Good Germination

We’ve been lucky with the weather since this planting. Conditions to promote good seed germination have been excellent. Remember the deep freeze we had in February? While it tested our human resiliency and strained our heating bills, it was good for this seeded prairie. Adequate precipitation and freeze/thaw action commenced throughout February and March. These conditions helped work the seed down into the soil while also breaking down their seed coats to help prepare them for germination.

Warmer temperatures along with rains in April and May promoted good germination. Identifiable prairie seedlings from the planted species list identified in the earlier blog post were evident amidst the expected seedlings of annuals like ragweed, sunflower, and foxtail.

Annual sunflower, giant ragweed, and foxtail grass serve as a shading nurse crop for tender, young perennial prairie plants

Thanks to the planting areas’ proximity to a water spigot, I was able to do some supplemental irrigation during the hot, dry weeks of late June and early July to keep the new seedlings from burning up while the seedling roots were small. But periodic rains in July and early August along with mottled shade from the nurse crop of sunflowers and annual grasses provided the conditions needed to help the prairie seedlings get well established as we head into fall.

Species Identified

A brief perusal of seedlings during this week’s seeded prairie checkup helped me find and photograph 14 of the 43 species that were part of the Prairie Moon Nursery seed mix. My prairie seedling identification skills are rusty, but I was able to identify the following seedlings to at least genus and some to species.

Seedlings of these identified species are thick throughout the planting and I’m confident that a good number of the rest of the 43 species in the mix will also show up eventually.

Weed Management

Typical management for a less-manicured seeded planting is simply to mow it a couple of times during the growing season to keep annuals from going to seed. Since such an approach for a higher profile area near the visitor center may look a bit scalped and perhaps not as appealing, we are taking the approach of cutting or pulling stems of the annuals. It is more labor intensive than mowing but not an unmanageable approach for small sidewalk edge planting, and regular volunteer, Gerry Selzer, has cheerfully embraced this task.

Attracting Insects

One of the main reasons for planting this diverse wildflower seed mix in addition to adding pretty splashes of flower colors, is to attract insects and biological diversity to our sidewalk edge prairie beds. In two or three years, these planted species will be flowering and attracting insects with their flower nectar and host plant vegetation. I look forward to engaging school kids and teachers with regular investigations of these sidewalk edges to learn more about relationship between prairie plants and insects.

Overall, I’m pleased with the progress of this planting as seen during this seeded prairie checkup. Days are getting shorter and we are almost to the cooler months of this planting’s first year when I can be pretty sure that these young prairie seedlings will have deep enough roots to survive about any weather conditions. Stay tuned for future updates about the development of this planting and consider how you too might add a seeded planting somewhere in your landscape.

Fireflies of Summer

The longest days of late June in Southcentral Kansas for me feel synonymous with sweltering hot swimming weather, carefree kids riding bikes, backyard BBQs, blooming milkweeds, butterflies, and the first signs of the fireflies of summer.

Saturday evening, June 12, 2021, I saw the first flash of a firefly in my backyard. I found many adult fireflies on the underside of milkweed leaves while looking for monarch caterpillars in my prairie garden. Over the last week, fireflies have begun putting on a dazzling light show in the early evening hours.

Firefly Diversity, Life Cycle, and Habit

Fireflies, sometimes referred to as lightning bugs, are neither flies nor bugs. They are beetles (order Coleoptera) in the family Lampyridae. Nearly 170 firefly species of Lampyrids have been documented throughout the United States and Canada.

Like all beetles, fireflies go through complete metamorphosis in four stages: egg, larva, pupa, and adult. The complete life cycle can range from two months to three years or more, the majority of the life cycle spent in the larval stage. The larva is a predator that eats soft-bodied invertebrates including earthworms, slugs, and snails. It first injects paralyzing neurotoxins to immobilize its prey. Then it secretes digestive enzymes to liquify it for easy consumption.

Fireflies have specialized light organs under their abdomens that produce the compound luciferin. Luciferin combined with oxygen undergoes a chemical reaction known as bioluminescence that produces light with almost no heat. Even the eggs and larvae of some species glow, hence the name “glow worm”. Adult males and females turn that light on and off to communicate in their mating ritual. Each species of firefly has its own distinct lighting pattern.

Research shows that this illumination system also deters predators. Just like a monarch butterfly has a bright coloration system to communicate that it is poisonous, fireflies send the message that their bodies are toxic by flashing. I have big brown bats living in my yard. I thought they would easily munch on fireflies since beetles are a favorite part of their diet, but this article helped me to learn otherwise.

Larry Buschman – Local Firefly Expert

I probably would not have become inspired to learn more about fireflies if it hadn’t been for meeting Larry Buschman. Larry is a total firefly nerd and a knowledgeable one at that. He travels throughout the Central United States every summer to look for and study different species of Lampyrids. Larry was kind enough to let me tag along last summer and observe him in action. When I met him for the first time in a parking lot along the Walnut River near El Dorado, he wasn’t hard to spot. With his red light head lamp, insect net, and his homemade contraption consisting of a “flashing system” and camera on a fishing pole to lure in and photograph various species, Larry looked like a character out of Ghostbusters. I knew right away I had met a new friend.

“Who you gonna call” if you want to identify fireflies? Larry Buschman.
Larry trying not to be annoyed by my flash camera messing up his night vision while he identifies a firefly specimen.

We set out for the deepest and darkest part of the riparian woods. As it got dark and Larry got to work luring in fireflies, we caught two different species of fireflies. We found Photinus pyralis “The Big Dipper” abundantly. This is the species that you and I probably most commonly see in our yards in Kansas. The males display five 1-2 second flashes regularly every 4-5 seconds, which elicits a similar one-time flash by the female.

We also found a less common species in the genus Photuris. This group is easily identified by its humped back and longer legs. Female adults of Photuris are often predators of other fireflies. While the long, slow flash narrows down the identification of this firefly to one of a couple of different species of Photuris (either P. caeruluscens or P. lucicrescens), Larry was not sure on the identification. So, for now it gets the more generic designation of Photuris spp. See more details about the firefly species of Kansas in Larry’s Field Guide to Western North American Fireflies.

Larry allowed me to take home and photograph the next day the two species we found.

Firefly Threats and Conservation

World Firefly Day is coming July 3-4, 2021 and marks a good time to think about their conservation. Firefly species around the world are threatened. A recent study identified that the three most prominent threats to fireflies are 1) habitat loss, 2) artificial light, and 3) pesticide use. Artificial light at night and pesticide use are two threats that we can curtail fairly easily and with minimal effort. Check out light pollution solutions and firefly-friendly lighting practices to help you reduce light pollution in your landscape. And consider the sensible approach of Green Scaping to reduce and even eliminate pesticide use in your landscape.

Addressing the largest threat to fireflies of habitat loss is one we can also take on in our landscaping. It is a drumbeat that we deliver regularly through our education channels at Dyck Arboretum. Building habitat for insects in general will benefit any subgroup of insects including fireflies. Plain and simple, you can do this by increasing the diversity of native plants in your landscape.

For further firefly conservation recommendations, check out the Xerces Society’s comprehensive publication Conserving the Jewels of the Night.

I’ll leave you with a favorite children’s book to share. Children will be an important part of firefly and insect conservation into the future. Consider how you might restore insect habitat, curb pesticide use, and reduce light population to help protect the fireflies of summer.

High Demand for Native Plants

Micro chips, new cars, used cars, houses, lumber, bikes, bike parts, energy,. . . and native plants. People really want these things right now. As vaccinations liberate Americans from their COVID hermitage, we get to see many distinct examples of high demand leading to short supply.

We learned during our recent Spring FloraKansas Plant Sale – when we moved ~16,000 plants over a four-day period – that there is a really high demand for native plants right now. Folks have spent more time in their home landscapes over the last year and are looking to practice ecological landscaping in levels we’ve never quite witnessed. It is fun for our staff to see this high demand for plants that please both wildlife and the people who plant them. FloraKansas is at the top of our list of events that help Dyck Arboretum of the Plains fully engage our mission to cultivate transformative relationships between people and the land.

A wildflower bouquet from my spring garden including columbine (pink), salvia (purple), rose verbena (light purple), golden ragwort (yellow), ‘Major Wheeler’ honeysuckle (red), and snowdrop windflower anemone (white) helps me appreciate native plants indoors too.

But our staff also experienced the stressful side of high demand and inadequate supply, as many wholesale plant orders either didn’t arrive as planned or came incomplete with numerous backorders occurring. Like never before, we had to scramble and pivot to convince members to consider options B, C, and D of a particular grass, wildflower, sedge, shrub or tree to replace option A that wasn’t in stock.

Calm before the storm – early morning light in the greenhouse before the first day of the plant sale.

We typically order most of our native and adaptable plants for our FloraKansas sale from wholesale providers that can produce the number of plants we need much more efficiently and cost effectively. However, during times like these when wholesalers are unable to meet demand, our thoughts turn to a couple of different methods of production on our own.

Digging and Transplanting

When a plant thrives in a given location and establishes a substantial root system, it will flower, set seed, and distribute new seedlings to its nearby surroundings. It will also often spread vegetatively via roots and develop a larger diameter crown. Both of these forms of reproduction offer us and you the opportunity to produce new plants.

Here at the Arboretum, weeding beds of grasses and wildflowers offers many opportunities to dig and transplant seedlings to new locations. Our grounds manager and horticulturalist, Katie Schmidt, is always plucking native wildflowers and grasses that are spreading where she doesn’t want them and either transplanting them to new locations or bolstering our plant sale.

An aspen grove has established nicely north of our Prairie Pavilion. But as clonal species do, it is now sending up unwanted root sprouts in adjacent wildflower beds as far as 20-30 feet away from the original trees. These are perfect candidates for digging and transplanting.
Yellow coneflowers that have spread in a bed will be potted and find a new home via our fall plant sale.

I like to divide older, established plants and move divisions around my yard. This establishment of new beds in my never-ending quest to reduce square footage of lawn takes physical effort, a good soil knife, regular watering in the first year, mulching and lots of weeding. But I enjoy the process, end result, and seeing the wildlife it attracts.

Plants that I transplanted from elsewhere in my yard have established nicely in less than two years: (counterclockwise around tree) coral bells (red leaf), narrow leaf coneflower, catmint, purple poppy mallow, mountain mint, and beardtongue penstemon.

Seed Collection and Germination

Our Dyck Arboretum Prairie Window Project reconstructed prairie was planted in stages from 2005 to 2010 with local ecotype seeds. The 120+ species planted include many great wildflowers, grasses and shrubs that are not always commonly available through the landscaping trade or even through our plant sales. This reality, and subsequently an opportunity, became apparent to me as I observed and photographed the following flowering species over the last couple of weeks following our sale.

I will be watching over the next few weeks for these species to be setting seed and monitoring the right time to collect these seeds. With proper storage (i.e., cool, dry place in paper bags), stratification (i.e., cold/wet treatment for 60-90 days for most species), and hopefully good germination in the greenhouse next spring, I hope that we will be able to offer these species to you next spring.

You too can be on the lookout for seed from unique and interesting species to add to your landscape, and you don’t need to follow the labor intensive approach just outlined. Simply scatter your collected seeds into your intended planting area in the fall and let nature (i.e., gravity, freeze/thaw action, precipitation, and typical winter conditions) do the work for you. While the outcome of this approach is less certain than options described above, it is certainly easier and can add an element of surprise to your gardening adventures.

Garden Small, Be Intentional

While taking time this weekend to weed the small native plant beds I have dotted around my landscape, I was reminded of the joy this tending process brings me. Not necessarily because I love weeding the seemingly endless emergence of hackberry seedlings and henbit sprouts every spring. But because it leads to my spending time with and being intentional in these gardens.

Weeding and Experiencing Wildlife

Of course, I want my gardens to look nice. But a big part of my intentionality in native gardening is knowing that it is a place to feed and host wildlife. And how will I notice and enjoy that wildlife if I don’t spend time looking for it? While weeding to help manage the human-desired aesthetics of this garden, I’m also being mindful of how this garden will look to insects, birds, small mammals, amphibians, and reptiles.

I know that the new flower emergence of rose verbena, celandine poppy, columbine, golden alexanders, golden ragwort, and woodland phlox all around me will attract wildlife. And sure enough, before long two pearl crescent butterflies make an appearance and land on nearby vegetation. Robins scratch through leaf litter nearby and grackles squawk overhead in the hackberry trees that gifted me their seedlings.

Columbine (Aquilegia canadensis) in flower

A tattered monarch (the first I’ve seen this spring) stops to sip nectar from a dandelion that I’m glad I hadn’t yet plucked. Unfortunately, none of the five species of milkweed in my yard (common, butterfly, whorled, showy, and green antelopehorn) have yet to emerge from dormancy. I’m guessing this female has carried eggs here all the way from Mexico and is looking to oviposit on milkweed stems. Soon, new shoots will be available to serve as monarch caterpillar food.

Next, a fresh-looking eastern tiger swallowtail butterfly flaps through with powerful flight while a Carolina wren sings loudly nearby, part of a resident pair that I enjoy seeing regularly. Then, a bumblebee visited a nearby columbine flower, reminding me not to mulch too heavily or thoroughly, because they commonly nest underground.

I’ve been at this native gardening process for decades now. But it seems that I see and learn something new almost every time I’m observant and present in the garden.

Start with Small, Manageable Gardens

If you are interested in a brief explanation how I got started with planning and planting some of my small gardens, HERE is an earlier blog post on the topic. The key is to start small and plant only what you will enjoy managing. If you don’t enjoy the regular process of weeding and tending your garden(s), then the process will not be sustainable. And for some native plant gardening best management practices, HERE is another blog post with advice.

Once you have your small garden site outlined and prepared for planting, consider one of the following wildlife-attracting garden kits of thoughtfully-selected assemblages of plants to fit your planting location. For more details about our FloraKS plant sale, click HERE.

Garden kits available at Spring FloraKS Plant Sale

To make sure you are successful in your gardening efforts and enjoy the process, be sure that you start small. Keep your effort manageable, and be intentional with your focus.

Landscaping with Native Kansas Oaks

Filtered light coming through a stately open-grown burr oak.

There are many appealing reasons to consider landscaping with native Kansas oaks. Oaks are

  • long-lived with strong branches,
  • can grow to be large and stately,
  • provide welcome shade from the hot Kansas summer sun,
  • allow some filtered light to pass through to allow growth of understory vegetation, and
  • enhance the wildlife diversity in any landscape by attracting insects.

Native Kansas Oaks

Kansas is predominately a prairie state. Fire and grazing have helped keep grasses and wildflowers as the dominant form of vegetation for thousands of years. Kansas does, however, get enough precipitation to support trees, especially many drought-tolerant species of oaks. And when they are not being burned or grazed down to the ground on a regular basis, they can thrive here.

With the Rocky Mountain rain shadow influencing the precipitation map for Kansas, we have increasing bands of precipitation moving from west to east across the state.

Trees generally need more water than prairie grasses and wildflowers. Therefore, it is understandable that eastern Kansas climate is most hospitable for growing trees. The following Küchler Vegetation Map of Kansas confirms the association between greater precipitation and the historical presence of trees by the location of oak-hickory forests, oak savannas, and other timbered regions in the eastern part of the state.

The trees that thrive throughout eastern Kansas may also be able to grow further west into Kansas, but will be limited to locations near streams or urban landscapes where they can receive supplemental irrigation.

Using the fantastic recently published book, Trees, Shrubs, and Woody Vines in Kansas by Michael Haddock and Craig Freeman, I compiled the following table of the oaks native to Kansas. I have listed the 12 native oak species in order from most to least common in Kansas. I did this to serve as a guide to the species that generally have the greatest tolerance to drought conditions and that are therefore more likely to succeed even in the drier parts of the state.

Attracting Wildlife

Regarding the benefits of oaks I provided in the introduction, I want to expand a bit on the benefits of attracting wildlife.

Filtered light sustains understory vegetation

Oaks in general and especially more drought-tolerant oaks like burr oak allow more light to filter through its leaf canopy to the understory than other tree species such as elms and maples. As I describe briefly in a post about a local, large burr oak tree, burr oak savanna plant communities of Eastern Kansas were historically able to support diverse arrays of grasses and wildflowers under their canopy that promote a healthy ecosystem of biological diversity. Urban folks can follow this model and grow prairie-like native plant gardens under the canopy of oaks. This also helps explain why it is easier to grow turf grass in the filtered light conditions under an oak than it is under the shadier understory of an elm or maple.

Oaks – the best trees for supporting wildlife

Professor Doug Tallamy in the Department of Entomology and Wildlife Ecology at the University of Delaware is a big proponent of using native oaks to attract wildlife. His book Bringing Nature Home: How Native Plants Sustain Wildlife in Our Gardens makes a strong case for using oaks to attract caterpillars, and subsequently birds that feed caterpillars to their young, to enhance the biological diversity of a landscape. His research shows that the oak genus (Quercus) attracts more caterpillars to its leaves, flowers, bark, acorns, and roots than any other genus of trees. In fact, this genus is so important to Tallamy that his most recent book The Nature of Oaks: The Rich Ecology of Our Most Essential Native Trees focuses entirely on the subject.

Five Favorite Oaks

While I think there are appealing components to all 12 of the native Kansas oaks, I have narrowed my focus for the purposes of this post to promoting five favorite oak species.

USDA maps denote the natural range of each species. A given tree may still thrive in say an urban area outside of this range when offered wind and drought protection from structures, other trees, and/or supplemental irrigation.
This 55′ wide by 45′ tall burr oak outside my office window is great example of how this species takes a wide-open stance when grown in full sun. The root structure cross-section drawing pasted proportionately below this tree was found in the Nebraska Conservation Bulletin Number 37.

Burr oak savannas were part of the focus of my graduate research and I simply love the majestic, strong-branched open-grown shape of this species. The shape and distinct look of a mature Q. macrocarpa specimen in winter is as interesting to me as its leafy green look during the growing season. It is bimodal in its moisture distribution, meaning it can survive in both dry upland conditions as well as low floodplain conditions. Thick, gnarly bark makes this tree more fire tolerant than most, and when top-killed, its taproot allows it to immediately re-sprout. The large acorn fruits (hence the Latin name “macrocarpa“) are food for many insects, mammals, and birds (e.g., turkeys and wood ducks). To appreciate the value of a burr oak to wildlife, click on this Illinois wildflowers link and scroll down to the impressive list of “faunal associations.” Burr oak leaves turn yellowish-brown before dropping in the fall.

The attractive ashy gray bark, toothy margined leaves and stately round shape of the drought-tolerant chinquapin oak make it an appealing landscaping tree. One-inch sweet acorns are a favorite food for many birds and mammals and the leaves turn yellow-orange to orangish-brown before dropping in fall. This species prefers well-drained soils but tolerates a variety of soil textures and moisture regimes.

Dwarf chinquapin oak only reaches a mature height of approximately 20 feet and certainly can be used in different landscaping scenarios than any of the four other medium to large landscaping trees recommended here. You may use it as a featured shrub or planted with many to form a screen. This species prefers sandy or clayey soils whereas the larger Q. muehlenbergii does best in calcareous soils. In spite of its small size, dwarf chinquapin oak can produce large quantities of acorns which along with the leaves and bark provide food for numerous species of insects, birds and mammals. This oak is known to produce underground runners to spread clonally.

Black oak is named for its dark bark color at maturity. It has a deep taproot with widespread laterals which make it a very drought-tolerant tree that is adaptable to a variety of soil types. It does especially well in sandy soils. As described for other oak species, black oak provides food for numerous insects, birds and mammals.

Shumard oak is a popular landscaping tree because of its strong branches, long life and red fall color. It is adaptable to a variety of soils and its acorns provide food for various types of wildlife including insects, birds, and mammals. Although its natural environment is along streams in Eastern Kansas, it is tolerant of drier areas further west in protected urban areas. A shumard oak I planted in my yard loses its leaves late fall, by around Thanksgiving.

Things to Think About

Tree size/location

When locating a tree, leaving room for the eventual size of the mature tree will save you or future caretakers time and money. Conflicts between growing tree branches and buildings, utility wires, city code street clearances, and branches of other trees can lead to tree trimming headaches, so consideration given to a tree’s height and spread is important. Also, the closer a tree is to a sidewalk or driveway, the more likely its roots are to alter the grade of and contribute to the cracking of that concrete.

How long will it hold its leaves?

Some oaks lose their leaves in fall, but others hold onto them until spring. I can think of a couple of reasons this may be important to you. If you like to do your leaf raking in fall, don’t choose an oak that holds leaves till spring. If you want your oak to cast shade in summer but not winter, be sure to choose an oak that drops its leaves in fall. For example, this may be an important consideration for a tree that shades a house in summer, but allows solar panels to work in the winter.

Oak leaves are slower to decompose

Know that oak leaves have higher tannin content than many other tree species, and therefore, take longer to decompose. I like to use all my tree leaves for garden mulch and since the oaks I’ve planted in my landscape are all pretty small still, this has not been a big concern. However, if you compost your leaves or have heard the myth that tannin-rich oak leaves will make your soil more acidic, read this article.

Slower growing trees still provide rewards

A common complaint I hear about oaks is that they grow too slow. Therefore, folks may opt for the short-term gain of quick shade provided by a poplar or silver maple instead of a longer lived oak. A poplar lifespan may be 30-50 years, a silver maple 50-100 years, and an oak 150-250 years. But what you gain in quicker shade with the poplar and silver maple, you give up in durability, attraction to wildlife, and passing along quality trees to future property owners. The above recommended oaks all would be considered slow to moderate rate growing trees. Do know that you can increase the growth rate of an oak with mulching, supplemental water, and fertilizer. Maybe it is the skewed perspective of an oak lover, but I would think that oaks even improve property value. And remember, a tree is planted for the next generation as much as it is for you.

Milkweed for Monarchs

In Kansas and throughout the central U.S. corridor, we need to plant more milkweed for monarchs. Because of human-caused reductions of host plant milkweed species through the monarch migration corridor, this butterfly is in decline. I will summarize the current plight of the monarch, review its life cycle and why it is in decline, and recommend seven milkweed species we should be planting more frequently in our urban landscapes to attempt to aid monarch recovery.

Experts monitor monarch populations by documenting the extent of area they occupy annually in their Mexican oyamel fir forest overwintering sites. While the numbers are variable from year to year, the overall downward trendline seen in the following graph is discouraging.

The following recent announcement highlights that the monarch warrants protection to stop its decline, but that too many other species needing protection are taking priority at the moment.

Monarch Life Cycle

From March to November, eastern populations of monarchs migrate from Mexico to Southern Canada and back every year. It usually takes four generations of monarchs to make this journey – two going north and two going south.

Various species of milkweed (Asclepias spp.) throughout the migration corridor of the central U.S. play host to hungry larvae as an essential element of the monarch life cycle.

Adult butterflies completing the first northern leg of the journey from Mexico to the south central states of the U.S. including Kansas are conditioned to find milkweed plants to lay their eggs in spring. Later generations returning south in late summer are doing the same.

Human Impacts

In a 2013 presentation at Dyck Arboretum, Monarch Watch’s Chip Taylor expressed that a loss of milkweed throughout this migration corridor is one of the top reasons for the monarch’s decline. The advent of no-till agricultural practices has been great for the efficient production of crops, but its broadcast spraying of generalist herbicides like glyphosate (i.e., Roundup) has also been very efficient at killing milkweed throughout the Plains and Midwest.

Loss of monarch nectar sources through habitat destruction, widespread use of insecticides, and climate change pose additional challenges to the monarch.

More Milkweed Needed

The monarch butterfly evolved along with the presence of prairie milkweed species throughout the Great Plains and Midwest during the 10,000 years since the last Ice Age.

Just as humans have rapidly reduced the presence of milkweed in the last couple of decades, we should be able to find ways to re-establish milkweed.

In a recent presentation, I promoted the planting of milkweed for monarchs and highlighted the diversity of 19 milkweed species found in Kansas. These species are well-documented in the book Kansas Wildflowers and Weeds by Michael John Haddock, Craig C. Freeman, and Janét E. Bare. Compiling information from Chip Taylor and a 2018 Iowa study in Frontiers of Ecological Evolution on milkweed preference by monarchs, I landed on promotion of the following seven yellow-highlighted species. With high monarch larvae survivorship, and being relatively easy to establish from plugs, these seven milkweed species are good selections to grow in any sunny garden spot.

Milkweed species in Kansas

To make a dent in the recovering milkweed presence throughout the monarch flyway, seeded milkweed re-establishment should be boosted in large-scale habitat areas like in between agricultural fields, along roadsides and in Conservation Reserve Program land just to name a few. But such efforts will require coordination with governmental agencies and lots of planning. What I will propose with the rest of this post will be what we can each do with our own plots of land. Consider planting plants in native plant gardens and collect and spread seed if you have areas that are larger and less manicured.

Common milkweed can get to be weedy in the garden, but it is easy to pull, so I don’t mind a little weeding because of the immense benefit this monarch favorite offers (prefers dry to medium soil, grows 4-5′ tall, and blooms in June to July with a very sweet fragrance).
Whorled milkweed prefers dry to medium soil, grows 1-2′ tall, and blooms in June to July
Butterfly milkweed prefers dry to medium soil, grows 1-2′ tall, and blooms in June to July
Green antelopehorn milkweed prefers dry to medium soil, grows 1-2′ tall, and blooms in May to June
Showy milkweed prefers sandy loam dry to medium soil, grows 3-4′ tall, and blooms in June to July
Smooth or Sullivant’s milkweed prefers medium to medium -wet soil and can be commonly found in the bottom of roadside ditches. It grows 3-4′ tall, and blooms in June to July. While a bit similar looking to common milkweed, smooth milkweeds differs with its smooth, non-hairy leaves that clasp the stem, and with more flat rather than rounded flower cluster.
As the name implies, swamp or marsh milkweed likes its feet wet, prefers wet to wet-medium soil like along a pond edge, grows 4-5′ tall, and blooms in August to September

As tempting as it may be to plant tropical milkweed (Asclepias curassavica) in an annual bed or a pot, try to avoid it. Even though it can host monarch larvae and the flowers are attractive for insects and humans alike. The following article from Xerces Society provides compelling reasons not to plant tropical milkweed in non-tropical areas. Holding monarchs in colder places longer than they should, and exposing monarchs to the protozoan parasite Ophryocystis elektroscirrha (or OE for short) are two of those reasons.

Come check out our Spring FloraKansas Native Plant Festival, April 22-26, 2021. There you will find a wide selection of milkweeds and other wildflowers, grasses, sedges, shrubs, and trees to enhance your landscape for monarchs and all insects!

Seeding After Disturbance

Dispersal of prairie wildflower seeds after sidewalk construction

I’d like to tell you about our late December sidewalk edge prairie seeding after disturbance following the installation of a new sidewalk right outside my office window.

Preamble about Disturbance

Disturbance is rich with meaning and ever-present.

In humans…

Our lives are filled with different levels of disturbance. While we typically trend toward stability and shy away from disturbance, we know unsettling events will happen. So, we try to be ready for them, use them as a resetting point, and work to make ourselves more resilient as quickly as possible going forward. How we respond to disturbance determines how quickly we recover in that quest to eventually make ourselves better.

In the prairie…

The same goes in native plant communities on the Plains. Disturbance is a natural and important element in maintaining a prairie ecosystem. While fire and grazing are two disturbing elements, they have ironically been prairie stabilizers for thousands of years. Without their occurrence on a semi-regular basis to knock back woody plants, prairies will be invaded by shrubs and trees and transition to woodlands and eventually forests in a manner of decades.

Fire and grazers also expose and disturb soil. In the spring, fire removes a cold-insulating organic matter layer, blackens the soil surface, and heats the soil profile. Hooves of grazers stir soil and buffalo wallows clear existing vegetation. Burrowing mammals of the prairie also stir up and expose soil. All of these activities encourage the germination of early successional forb seeds in the soil seedbank that attract unique species of wildlife in biological diverse prairie. Disturbance is not only good for the prairie, but it is essential.

In this sidewalk-lined prairie garden…

Ever since the new sidewalk was installed summer of 2020, the adjacent soil in 2-4′ zone of disturbance on either side has been bare. The vegetation in these areas prior to disturbance consisted of native prairie grasses and the occasional prairie wildflower. But after this soil disturbance, annual weeds will explode from these areas come spring. It may have been 40 years since this site was a farm field, but I guarantee that the agricultural nonnative and native annuals brought in by years of farming, including species like henbit, foxtail, and ragweed, will profusely germinate here in a few months.

A Unique Opportunity

These sidewalk edges have been an important educational resource over the last 15 years. Thousands of students, from Kindergarten through college-age, have studied them for plant and insect diversity via field trips and labs. School teachers participating in our Earth Partnership for Schools summer institutes and classes of master gardeners and master naturalists have also gotten in on the sampling of these areas each fall.

Over these years, I’ve noticed that tall native prairie grasses, including big bluestem, Indian grass, switch grass, and eastern gamma grass, have come to dominate these sidewalk plantings, while wildflowers have slowly gotten crowded out. Frankly, these plantings needed some disturbance to break the grass stronghold and provide a window of opportunity for an infusion of new species.

Rather than discourage with herbicides the germination of annual weeds and grasses sprouting from roots along this disturbed sidewalk edge, we decided to plant a native wildflower mix to offer hearty competition. We chose a diverse array of colorful flowering prairie species desirable to human eyes and insect pollinators alike. The sports adage that “the best defense is a good offense” certainly fits our approach to the ecological restoration of this sidewalk edge.

Seed Mix

Prairie Moon Nursery offers a nice array of prairie wildflowers with historical range into the mixed/tallgrass prairie of Kansas. I went through their seed inventory and chose all the species that I know from regional prairies (with a few exceptions). A nice summary of other seed and plant sources can be found through Kansas Native Plant Society. The developed species list amounted to the following 43 species, representing a variety of heights, colors, and bloom times and should add a nice diversity of plants and eventually wildlife to these areas.

I was sure to omit species that would be aggressive as they are in nearby gardens and will eventually invade on their own. The mix for 1,000 square feet was calculated to be planted at a generous rate of 73 seeds/sq. ft. (50 seeds/sq. ft. is what I recall to be a minimum industry standard) This cost us $171.20 including shipping and a $50 mixing fee for orders under $200.

Planting Process

We pushed to get this seed ordered and delivered as early in the winter as possible. I like to aim for December, but have planted in January also. Different wildflower species require various types of treatment/stratification for best chance of germination, but a general successful approach is aiming for 2-3 months of cold-wet conditions (a typical winter) that will lead to the best rate of germination possible. After receiving the seed, we proceeded as follows…

Seed mix from Prairie Moon Nursery

Mix seed with bulk

We used sand, but mixing sawdust, kitty litter, or other media with your seed will do. The seed will seem like an incredibly small quantity of material to spread over a large area and adding bulk material helps increase the chances that you will cover the entire planting area with seed.

Dividing mix evenly into planting areas

A supply of 5-gallon buckets is helpful to divide the seed/bulk material mixture into even quantities that match the number of even-sized planting areas. To give yourself a reserve quantity of seed, I recommend doubling the number of seed quantities per planting area. For example, we had two sides of sidewalk to plant, and prepared four buckets of seed. Cover each planting area with one bucket and then do the same again with the second bucket. If you blow it with the first bucket and don’t cover the entire area – which is easy to do – then you have a reserve bucket to finish the job.

Raking planting area

Good seed/soil contact is the goal to encourage seed moisture absorption and improve germination once an average soil temperature of 55 degrees F is reached in the spring. There was some dead plant debris covering our planting areas, so we raked the areas before planting.

Raking the planting area prior to seeding

Dispersing seed

Seed dispersal is easy by hand and probably most successful when conducted with bare hands so you can feel the seed mixture, if you can keep them warm on a cold day. But standard handheld or rolling push-behind broadcasters could also be effective. More sophisticated seed drills calibrated to specific seed sizes are not very effective with mixes containing various sizes and textures of seeds like we were dealing with.

A final raking

While not an essential step, we had the human power and time to do a light final raking after planting to barely cover the seed. You want to be careful to not bury small seeds too deeply. Seed planting experts often advocate for allowing nature and its powers of freezing/thawing, precipitation, and gravity to work the seeds into the top 1/8-inch of soil throughout the course of winter.

Follow-up

Moisture and frozen ground are now what we wish for

Most of the work is now finished with this planting and the main job in follow-up as we look forward to colorful, flowering wildflowers throughout the growing season is to have patience. While a few species like black-eyed susan, wild bergamot, and yellow partridge pea may flower in the first couple of years of this planting, most species in the mix won’t flower until year three or longer.

It will be difficult to think of this planting as anything other than a complete and utter failure in the first year when all you can mostly see are weeds. However, careful inspection should show in this first growing season that small sprouts of prairie species hidden close to the ground are there. Prairie wildflowers develop deep, 5-15 foot root systems to help them survive for years and even decades through harsh Kansas summers and that process takes time. About all we can do is mow the planting area as high as possible once or twice each year in the first few years to keep annual weeds from going to seed and reduce their competition with prairie seedlings for light and water.

My friend often refers to the sage advice of Frog and Toad after a planting. I will follow her lead and leave you with this message as there is little left to do…

2020 Year in Review

2020 might be considered a “dumpster fire” as I’ve seen referred to many times on social media. Our Dyck Arboretum staff felt that way at times about 2020, especially earlier in the year. Cancellation of our 10th annual Leprechaun Run, education lectures, native plant classes, rentals, Prairie Window Concert Series shows, our cornerstone Earth Partnership for Schools Program 14th annual summer institute, and so forth, sure had me feeling down in the dumps for the early part of the year.

First impressions can be deceiving. What might appear to be a destructive, out-of-control prairie fire, was actually an in-control prescribed burn where disturbance is having a beneficial effect. This could be a sort of metaphor for 2020 where things weren’t always as bad as they seemed.

When I first started thinking about a 2020 year-end blog post, I figured why would anybody want a recap of a dumpster fire?! But then I thought about all the lessons we learned about ourselves this year. Rather than avoid the subject and focus on the negative, there was a lot of silver lining effort put forth this year. We took stock of all our lemons, and were able to make a lot of lemonade in 2020.

The first event of a normal year is the early January one-day reunion of our previous year cohort of Earth Partnership for School teachers. It might have been a bit foreboding of what was to come in 2020 when our anticipated reunion with 35 teachers from one of our largest ever annual cohorts was diminished to a handful of hearty souls by an icy winter storm.

The weather disruptions continued as storms delayed our late January and late February Winter Lecture Series events featuring presentations about Kansas bird populations and distributions and the story of a beloved local bread-baking entrepreneur. Thankfully, the first two of these three scheduled winter lectures were able to be rescheduled and delivered, but the third was altogether canceled due to the pandemic.

We will all have lifetime memories of events or trips or gatherings that we remember as the last that happened for us before the COVID-19 shutdown of 2020. Mine was a March 9th Dyck Arboretum board meeting where we surmised that coming events “might be a bit disrupted”. *Insert ominous music*

All of a sudden, virtual meetings were the new normal

As we know, COVID-19 shut down our social lives that second week in March and initiated a series of cancellations for Dyck Arboretum. My first step of adaptation was to figure out how to deliver a virtual presentation, as I clumsily did for a dozen folks interested in developing rain gardens.

We were sure that somehow, delivery of our mission statement would still be important whether it was safe for folks to gather in person or not

One of the events critical to our mission and budget is our spring plant sale, and the 2020 sale was racing toward us in a calendar clouded with uncertainty. We determined that we simply had to figure out a way to deliver plants safely.

We were already planning in January and February to order, grow, and deliver more plants than ever in the history of FloraKansas. When COVID hit, shipments like this one were already being delivered.

So, we put on our Arboretum big girl and big boy pants, got creative and figured out how to solve some problems. We virtually networked like crazy, bolstered our website for virtual orders, and planned for contactless curbside pickup. We learned a lot in the process and our native plant gardening members came through for us in a big way with their orders.

We knew that plants would not stop growing for a virus and tried to figure out how to commence with grounds maintenance activities safely without our regular cadre of retired volunteers. Local college students cooped up at home while doing remote learning heartily answered the call to help us with various grounds maintenance activities.

As we learned early on what activities were deemed to be COVID-safe, being outdoors and getting exercise was more important than ever for maintaining mental and physical well-being. Walkers on our Arboretum path were more abundant this spring/summer/fall than we can ever remember. With folks doing more gardening at home, an interest in native landscaping seemed to reach new heights.

Dyck Arboretum horticulturist Katie Schmidt, and office manager Janelle Flory Schrock answered the native plant frenzy by starting a “Plant of the Day” campaign on social media

By late summer, we became a little more savvy with remote delivery of educational materials and we delivered our first ever virtual Native Plant School. We were blown away by the interest in these classes as our members and the general public signed up and participated at three to four times the normal rate we had seen in past years.

Outdoor events such as walking meetings around our 1/2-mile path or weddings and theater events in our outdoor amphitheater became much more the norm.

The monarch migration was more memorable at Dyck Arboretum than I can ever remember in September of 2020. Not only did the butterflies stop for a few-day layover in a phenomenal way, but an avian predator enjoyed their presence as well. HERE is a more detailed telling of that story.

The end of the calendar year at Dyck Arboretum has long been marked by the holiday-themed winter Luminary Walk during Thanksgiving weekend and the first weekend in December.

We knew that the usual groups of indoor gatherings in our buildings around hot drinks and cookies and close huddling around the bonfire would not happen this year. But with strict adherence to COVID safety protocols and some creativity and dedicated volunteerism from members, board members, and Hesston College musicians, we were able to say the “show must go on”. You all responded admirably and supported us heartily.

2020 was a trying year for all of us. But it also taught us something about ourselves, about resiliency, and finding something positive through adversity. You, our dedicated members and volunteers, were so critical to helping us find this positivity in what could have been a destructive year. For this, we are so very grateful.

Holiday greetings from our Arboretum family to yours and we look forward to seeing you in 2021!
