Insects – Motivation for Native Landscaping

Posted on September 9, 2021 by Brad Guhr

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.

*Gulf fritillary nectaring on prairie dock*

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?

*Simple image of a prairie food pyramid (**Credit:** Mariana Ruiz Villarreal (LadyofHats) for CK-12 Foundation)*

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.

*Tour participants observing monarch caterpillars and milkweed longhorn beetles on common milkweed*

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.

Plant Profile: Black-eyed Susan

Posted on September 1, 2021 by Scott Vogt

Black-eyed Susan (Rudbeckia sp.) are one of the most recognizable summer-blooming wildflowers. Their bright yellow flowers explode in the summer and are covered with all sorts of pollinator activity. Bees, flies, butterflies, and beetles feed on its nectar and pollen. The fruiting heads also provide seed for birds over the winter. Here is a look at a few species and cultivars worth trying.

Missouri black-eyed susan (Rudbeckia missouriensis)

In the wild, Missouri Black-eyed Susan grows in rocky limestone glades, barrens, and tallgrass prairies. It ranges from Illinois and Missouri, south to Arkansas, Oklahoma, and Texas. Although not native to Kansas, I have found it very resilient and quite adaptable to various growing conditions. It has large bouquets of bright yellow flowers atop 18” stems. The foliage is narrow with the leaves and stems covered with a dense fuzz. It’s a nice addition to the front/middle of any border or informal meadow landscape.

Brown-eyed Susan (Rudbeckia triloba)

This native gem can be found in eastern Kansas and on into much of the southeastern Great Plains. It grows naturally in open woods and savanna areas with medium to moist soil. Each plant can produce loads of charming, warm yellow daisy flowers with brown button centers. It keeps pumping out blooms through much of the later summer through fall. The slender branched stems are surprisingly sturdy and help the plant reach an ultimate height of three to four feet. It is a wonderful habit plant with blooms for pollinators and seeds for birds. It does self-sow, so know that it will move around. You will need to selectively weed plants out of your landscape, if you are agreeable to that sort of thing.

We have carried a cultivar of Brown-eyed Susan called ‘Prairie Glow’ with attractive flowers of burnt orange with yellow tips surrounding a chocolate center cone. ‘Prairie Glow’ prefers full sun to light shade, and is also adaptable to many soil conditions.

Sweet Black-Eyed Susan (Rudbeckia subtomentosa)

Sweet black-eyed Susan grows throughout much of the central and eastern Great Plains in low, moist soil of thickets, creek banks, pastures, prairie ravines and ditches. The flowers are spectacular and rival sunflowers in quantity of blooms, if the root system can find consistent moisture. A large variety of insects love the nectar and/or pollen of Sweet Black-eyed Susan and flock to the blooms during July, August and September.

This is a great plant for a full sun to part shade location, but only when there is ample moisture. It will not endure dry soils. Plant it by a stream, water garden or pond where water is available on or near the surface. ‘Henry Eilers’ is a nice cultivar discovered in Illinois as a stabilized mutation with rolled or quilled ray petals. This cultivar reaches five feet tall and two feet wide. ‘Little Henry‘ is a shorter form which grows 3 to 4 feet tall but has the same quilled flowers.

Black-Eyed Susan (Rudbeckia hirta)

There are many forms of this poor man’s daisy, because it is so easy to hybridize. Typically, the species is found in full sun to part shade in mixed and tall grass prairies as a short-lived perennial or annual. It seeds readily and is a favorite to include in many prairie seed mixes. The bright yellow blooms from June through September are a welcome sight in any landscape from prairie to wildflower seeding. Some cultivars available are ‘Cherry Brandy, ‘Prairie Sun’, ‘Cherokee Sunset’, ‘Indian Summer’, ‘Autumn Colors’, ‘Denver Daisy’, ‘Goldilocks’, ‘Goldrush’, ‘Rustic Colors’, ‘Sonora’, ‘Toto Gold’, and ‘Toto Lemon’.

Cutleaf Coneflower (Rudbeckia laciniata)

This species grows in similar habitats to sweet coneflower – moist soil of creekbanks, thickets and open woods. A cut leaf coneflower really stands out in full sun and adequate moisture. The leaves are deeply lobed and the large, wide clumps, two to four feet across, can reach five to six feet tall. Each stalk can have multiple large flowers with a greenish-yellow central cone. They bloom from July to October. A garden worthy cultivar of cut leaf coneflower is ‘Herbstonne’.

Orange Coneflower (Rudbeckia fulgida)

This eastern United States black-eyed susan is one of the most widely used in horticulture. Many cultivars, varieties and subspecies are incorporated into landscape designs. The native form thrives in glades, meadows, and prairies. Rudbeckia fulgida var. deamii, Rudbeckia fulgida var. fulgida and Rudbeckia fulgida var. speciosa are two of my favorite native forms of orange coneflower. They grow well in landscapes with medium to moist soil and plenty of sun. These clumps slowly spread by rhizomes ultimately forming a dense mat of dark green leaves. The blooms pop up from July through September.

‘Goldsturm‘ was a popular cultivar, but it has been used less because it has issues with septoria leaf spot and powdery mildew. New forms like ‘American Gold Rush’, ‘Little Goldstar, and ‘Viette’s Little Suzy‘ have resistance to both septoria leaf spot and powdery mildew. These are great alternatives to ‘Goldsturm’.

Giant Coneflower (Rudbeckia maxima)

*Prairie Dropseed (foreground), Rudbeckia maxima, and yellow coneflowers*

I love this coneflower for its blue green leaves and large coned flowers in June and July. It makes quite a statement in the landscape with flower stalks to six feet. Native to Texas, Oklahoma and Louisiana, I have found it to be quite adaptable. It appreciates regular moisture but can handle some dry periods. Birds eat the seeds from the large cones during the winter.

There is a Rudbeckia for just about any landscape situation with full to part sun and wet to dry. Pollinators love them and birds too. Add some to your garden for their late season bloom.

Seeded Prairie Checkup

Posted on August 10, 2021 by Brad Guhr

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.

*Sidewalk edge seeded planting site this week on 8/10/21*

*The same planting site on the day it was planted 12/28/20 w/ planters Janelle and Kendra*

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.

IL Tick Trefoil (*Desmodium illinoense*)

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.

*This weedy sidewalk edge vegetation is shading and hosting a variety of prairie seedlings underneath*

*The rare and coveted Gerrius selzeranii*

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.

*A new black-eyed susan is already playing host to caterpillars, possibly of species of checkerspot butterfly*

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.

Garden Retreat

Posted on July 28, 2021 by Katie Schmidt

As much as we love our work at the Arboretum, sometimes the staff need to get out and about! Once or twice a year we take a staff retreat, spending a day in leisure time together. We eat, laugh, and explore new places. We often visit other gardens or notable landscapes on these retreat days. Luckily, Wichita has two great locations to see beautiful gardens: Botanica and the Wichita Art Museum. Click here to learn more about how your Dyck Arboretum membership gives you free admission to these places.

Mi Garden et Su Garden

Visiting other gardens is always a treat for us plant nerds, and Botanica never disappoints. It has seventeen acres of sprawling gardens including the Chinese Friendship garden, a woodland glade, a prairie-inspired meadow, a butterfly house and a children’s garden. With interactive statues and countless water features, there is excitement around every corner. Although our mission and goals are very different from Botanica’s, we can still draw inspiration and fresh ideas from their exhibits. They have many vibrant annual plantings featuring coleus, begonias, cannas, and more. These would be unsustainable for our garden, given our smaller staff and water-conscious focus, but the color combinations and design principles could be implemented within our ethos of ecological native plantings.

*Arb staff enjoying the children’s garden at Botanica.*

Botanica does a fabulous job of seamlessly mixing classical garden designs and exotic, tropical plants with prairie favorites. While it is no doubt labor intensive to maintain, the effect is undeniably beautiful.

*Their boardwalk and pond includes views of water lilies, lotus flowers, pickerel weed, and many other stunning aquatic plants.*

What a WAMmy of a Retreat!

The Wichita Art Museum is full of priceless paintings and sculptures inside, but also has an 8-acre ‘art garden’ outside. The plantings feature prairie natives like coneflower, switchgrass, side-oats grama, alliums, and rattlesnake master. These familiar plants are growing in modern designs, grouped in masses to create large swathes of color and form. As a backdrop for sculptures and surrounded by interesting walkways, the prairie species look wild and yet orderly. They also provide great pollinator habitat in an otherwise urban, nectar-less area. Prairie plants require less water than traditional landscaping, making these gardens green in more than one way.

Mass plantings featuring fountain grass and catmint make a dramatic effect at the WAM. As we have learned here at the Arb, mass plantings are also easier to weed and maintain, especially for volunteers and staff who may be less familiar with the plant material.

The Wichita Art Museum has set their massive outdoor sculptures within several prairie-themed garden spaces. Brad is taking this photo while Scott and I chat about grass varieties and Janelle, the truly wise one among us, seeks shade to prevent a sunburn!

*WAM infuses every space with a modern, clean-cut feel. The stepping stones cut an orderly path through a dense planting of grasses.*

What a joy it was to take a day away from the Arboretum office, the greenhouse, and the ever-present crabgrass to explore other gardens and refresh our mindset. I returned to the Arboretum with renewed appreciation for what makes our garden unique and what our mission charges us to do, but with new inspiration for how we can do it better. If you are an Arboretum member, be sure to take advantage of that reciprocal membership. Visit these Wichita institutions and support them if you can.

Soil Is Alive

Posted on May 5, 2021 by Lorna Harder

“ . . . most of us rarely give any thought to the fact that the ground beneath our feet is a complicated, ever-moving tangle of rocks and animals and plants and water and chemical compounds that rivals the ocean as a wild, dark mysterious, and inscrutable realm.”
Farming with Soil Life. https://www.xerces.org/sites/default/files/publications/19-051.pdf

Many of us garden for wildlife, choosing native plants that provide vital shelter, food and habitat for a diversity of species. However, the soils in which our native plants grow also play an important role in the success of our native gardens. Soil is alive! Let’s dig deeper into this “wild, dark, mysterious, and inscrutable realm that is soil.”

Soils Function

Soils are a medium for plant growth, anchoring roots, and also soaking up the nutrients, water and air that plants need to grow.
Soils store and filter water. The pores between soil particles, created by roots and animal tunnels, capture and hold precipitation, where it is available to plant roots. The water-holding capacity of soils is also important in reducing erosion and flooding. Soils also filter water, degrading and removing contaminants as it moves downward through soil layers to become groundwater.
Soils recycle and store organic material. Bacteria, fungi, insects and a host of other organisms decompose once-living plants and animals, producing organic material that can be used by living plants and animals for growth, maintenance and reproduction. Organic materials also store carbon, sometimes for centuries! This function helps mitigate climate change.
Soils are habitat for wildlife. From large to small, many animals burrow, nest or hibernate in soil. Animal movements in soils contribute to soil health by continually aerating, churning and mixing.
Soils are an engineering medium. Humans use large amounts of soil for construction and engineering projects. Little construction could be done without soils.

Soil Composition

Soils are composed of both living and non-living elements. Non-living minerals and rocks – soil particles of silt, sand and clay – intermingle with living elements to produce a unique mix of physical, chemical and biological properties that vary from region to region.

Soil Life

A teaspoon of healthy soil holds more living organisms than there are people on earth – 700 billion plus. Moreover, there are more different kinds of living organisms in the soil under our feet than there are living on top of the ground, from the microscopic to large insects. Together these soil organisms form a complex food web that makes life more livable for all of us.

Let’s take a look at some of these “little things that run the world.”

Bacteria. Microscopic soil bacteria are by far the most ubiquitous organisms living in soil. Bacteria play important roles both in decomposition, and in fixing nitrogen.

Rhizobial bacteria live in nodules on the roots of legumes (pea and bean family), converting atmospheric nitrogen into compounds that the plants use. In return, rhizobium receive sugars from the legume – a symbiotic relationship.

*Rhizobial nodules on the roots of a legume.*

Protozoans. Living in the water film surrounding soil particles are single celled protozoans. As predators, decomposers and consumers of bacteria, protozoans are important in nutrient cycling.

*Single celled protozoan between soil particles*

Fungi. Soil fungi are diverse in shape, size, form and function. Some are single-celled, others are multi-cellular. Most are beneficial, contributing to decomposition and nutrient recycling.

*Mycorrhizae on roots. Note the web-like extensions that absorb water and nutrients from the soil.*

One noteworthy group, the mycorrhizal fungi, live symbiotically with roots, enhancing nutrient and water uptake in the roots. In return, mycorrhizae receive sugars. More than 80% of the plants on earth have relationships with mycorrhizae.

Tardigrades. Also known as water bears, tardigrades are as big as the period at the end of this sentence. Tardigrades are predators and omnivores.

*Tardigrades generally live in leaf litter and the top 1-inch of soil.*

Nematodes. Nematodes can be predators, fungivores, bacterivores, omnivores, or plant parasites. They also disperse bacteria, carrying and excreting bacteria as they move through the soil. Nematodes tend to be found in water films within soil.

Mites. Mites are important predators and decomposers. They break leaf litter down, making it available to smaller organisms. Mites are abundant and diverse and can be found from the soil surface to deeper soil layers. Depending on the species, mites feed on everything from bacteria, fungi, algae, and dead plants and animals, to insect eggs, nematodes, other mites and springtails.

Dwarf millipedes. Dwarf millipedes are decomposers, fungivores, herbivores and scavengers. Moving through pore spaces in the soil, they are typically found around roots.

Springtails. Springtails come in all shapes and sizes. They feed on dead plant and animal materials, often in the top layers of soil and in leaf litter. They are so named because of their tail-like structure that enables them to jump a short distance. As decomposers, they contribute to nutrient availability in soils.

Earthworms. Earthworms are perhaps the best known of soil creatures, and their contributions are well-known: mixing and aerating soils, and distributing nutrients and minerals in their waste.

*Worldwide there are more than 7,000 species of earthworms.*

Centipedes. Centipedes are predators, and they are fast runners, sometimes chasing their prey. They eat earthworms, and other insects, large and small, injecting venom to paralyze and kill their prey.

*Centipedes can be found in shallow to deep soil layers.*

Spiders. As predators, spiders are important in controlling other insect populations. Underground dwelling spiders also contribute to soil mixing and aeration.

*Wolf spiders live underground. Females can carry up to 100 young on their backs.*

Beetles. The tiger beetle is just one of a host of insects that spends the larval stage of its life in soil. Both larva and adult are predators. Larval tiger beetles are predators, feeding on other insects on the soil surface. Tiger beetle larval burrows can be 18” deep.

*Tiger beetles are fast-moving hunters, chasing prey on the ground surface*.

These are just a few of the millions of organisms that live in the soil under our feet. All are important in maintaining healthy, productive soils.

Here are four tips to support underground wildlife, large and small, in the soils in your garden:

Disturb the soil as little as possible. Tilling and digging disturbs and damages the soil food web.
Grow a diversity of plants. Different species of plants add and remove different compounds from the soil, creating more diverse conditions for the organisms living in the soil
Keep living roots growing in the soil for as much of the year as possible. Roots feed living organisms in the soil.
Keep the soil covered with dead plant material. Mulch not only protects the soil from drying out fast, but it also feeds the decomposers, which are then eaten by other living things. If you want healthy soil, you should not see it very often!

Soil wildlife makes your prairie garden grow. Protect it!

Garden Small, Be Intentional

Posted on April 19, 2021 by Brad Guhr

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.

*4/19/21 Map of first sightings of adult monarchs at Journey North website confirms that I should now start to see monarchs in South Central Kansas*

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.

From Lawn To Lush

Posted on April 7, 2021 by Katie Schmidt

Lawn alternatives are more than just a passing craze. They are a great way to reduce your carbon-footprint and increase pollinator habitat. I am excited to present a class this week on this very topic, and thought it might be nice to preview it here on the blog.

I replaced a large section of lawn at my own home, and instead planted with bluebeard, perky sue, sedum, prairie drop seed, Mexican feather grass, horsetail milkweed, and lavender. The violets came up on their own, and in hordes! But I leave them there because they are host plants for fritillary butterflies.

Cost over the ‘Lawn’ Haul

Traditional lawns of cool season grasses such as fescue and Kentucky blue grass have a wonderful place in my heart. They are great for entertaining, playing family games of badminton or throwing a Frisbee for the dog. But all that green space adds up: Kansas alone has 157,000 acres of turf and lawn, according to data from 2006 released by the KSDA. In that year, it cost Kansans an average of $1,541 per acre to maintain the turf grass in our state. So we end up with lots of grass, lots of money spent, but little to show in terms of habitat, soil health, or carbon sequestration.

Volunteers helped us plant our Sundial bed near the Visitor Center. The planting is dense and diverse, but is balanced well by the solid green of the fescue lawns around it and the tidy limestone edging.

Lawn Alternatives Bring Balance

Rather than villainizing turf grass and framing it as the epitome of all native landscaping evils, a symbol of a Eurocentric society ,obsessed with outward displays of status that date back to palaces and aristocratic practices of a bygone era….I choose to focus on balance. We must balance our love of flat, green, monoculture lawns with the urgent need for diverse native plantings. By converting some areas of your lawn to forbs, shrubs, native grasses and groundcovers, you gain interest and beauty and ecological benefits.

This home in Oklahoma has skipped the traditional grass lawn by planting shrubs and perennials around pathways/hardscape. The sidewalks keep it looking organized and also make for easy access to the beds.

Garden Inspiration for 2021

Posted on January 6, 2021 by Scott Vogt

In this season of overwhelming change and uncertainty, one of the places that has brought me solace is my home and landscape. I don’t believe I am alone in seeking garden inspiration these days.

Many people are discovering the peace that comes from gardening and adding plants to their lives. We have been stuck at home so it gave us the opportunity to focus on the immediate space around us. There’s something satisfying about planting something, tending it and then watching it grow. It is also very satisfying to create a diverse habitat that brings wildlife to your yard.

In 2021, engaging in gardening activities will continue to be a very important and necessary part of our lives. Here are a few bits of garden inspiration for this season of change:

Garden as Teacher

More people than ever got back into their gardens last year. That trend will continue in 2021. Gardening can help us in so many ways and even gardening failures hold important lessons to be learned. New or experienced gardeners will embrace getting their hands dirty while growing their own food, creating a habitat garden, learning gardening basics or creating a landscape design. Many people are turning to their gardens for a place to escape, relax and unwind.

Natives First

Sustainability has become more important to gardeners. Gardeners are looking for information about how they can make their gardens more environmentally friendly. Choosing native perennials that grow best in our region should be the starting point for any new landscape design. Their deep roots and adaptability will conserve natural resources. It is crucial that you match plants to your site. For example, put plants that need more water in spots where the soil stays moist. Use our Native Plant Guide or the National Wildlife Federation’s Native Plant Finder to identify plants suited for your area.

Enhancing Nature

We are no longer gardening just for our own enjoyment, but also for the restorative effect our gardens can have on nature. Our gardens can become havens for birds, bees, and other pollinators.

Our staff recently heard a presentation from entomologist and author Doug Tallamy. He shared his vision of transforming 20 million acres of North American lawns into a “homegrown national park”.

“…each of the acres we have developed for specific human goals is an opportunity to add to Homegrown National Park. We already are actively managing nearly all of our privately owned lands and much of the public spaces in the United States. We simply need to include ecological function in our management plans to keep the sixth mass extinction at bay.”
Douglas W. Tallamy, Nature’s Best Hope: A New Approach to Conservation that Starts in Your Yard

Our gardens, no matter the size, can have an impact in sustaining wildlife and reversing the perilous trends that are endangering nature’s delicate balance.

Growing Food at Home

In this pandemic, growing your own food is both therapeutic and reassuring. Foods of all kinds have been grown is all sorts of spaces: in containers on a balcony, in raised beds, or large garden plots, homeowners are more interested than ever in growing their own food. If you want to learn more about growing your own mushrooms, join our Mushrooms in Kansas Symposium.

Going Online for Garden Inspiration

This trend is not going away anytime soon. There is a wealth of information at the click of a button online. Searches can reveal more than you ever wanted to know about perennials, trees and shrubs. With limited in-person learning opportunities such as our Native Plant School classes, you can now learn just about anything from the comfort of your own home.

However, it is important that you be discerning in what you try out in your own prairie-based landscape. Take recommendations with a grain of salt, become familiar with your own piece of land and read critically. Just because it looks beautiful in Virginia doesn’t mean it should be planted in Kansas.

Curbside (Greenhouse-side?) Pickup

It is so convenient to put in an order online and pick it up two hours later at the grocery store. This trend is obviously happening at garden centers and plant sales as well. We will again be taking orders online for our Spring
FloraKansas Native Plant Festival. We are committed to providing a safe process for Kansas gardeners to get the gardening plants and supplies they need for their landscape spaces.

Styles and trends come and go. There are plenty of trends to use in your garden, this year and every year after that. Ultimately, you will embrace the trends that mean the most to you. Hopefully, your garden will deeply inspire and impact you and the natural world in a positive way in 2021.

2020 Year in Review

Posted on December 29, 2020 by Brad Guhr

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.

*Teachers from Truesdell Middle School give a presentation about prairie gardening lessons they have been doing with their students*

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.

*Chuck Otte, an expert birdwatcher, extension agent, and the Kansas Bird Listserv database manager gave our first winter lecture*

*Sharon Entz, owner and head baker of Crust & Crumb Bakery, has incorporated her Mennonite farming heritage and expertise in milling science into her craft*.

*Delicious Crust & Crumb Valentine galettes served at intermission of the Prairie Window Concert Series*

*Missy Andersen & Her One Man Band gave the PWCS audience a great show in early February*

*Flagship Romance was a popular artist as part of our PWCS in early March*

*Little did we know that this full house crowd would be the last we would host indoors for a while*

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 certainly got our steps in early April filling plant orders for members and the general public*

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.

*College student labor is very beneficial to have on hand for the labor-intensive process of conducting a prescribed burn*

*Native landscaping graduate student, Ashley Akers, provided invaluable assistance to Arboretum staff this summer*

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.

*Interest in outdoor weddings at Dyck Arboretum of the Plains was more popular than ever in 2020*

*The Hesston College Theater production of Charlotte’s Web was a huge hit this fall*

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.

*Monarch fallout at Dyck Arboretum in September*

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.

*Lights in native grasses add unique ambiance when enjoying a prairie garden in its dormancy*

*Hesston College faculty member, Ken Rodgers, plays the piano in the Prairie Pavilion winter wonderland “snow globe” for visitors outdoors via a remote speaker*

*A Palette-Palooza decorating contest added nicely to the festive scene*

*Tri-bike excursions with neighboring Schowalter Villa residents have become a regular and welcoming scene in 2020*

*Favorable weather and scheduling allowed for helping Arboretum board member, LeAnn Clark and her husband Stan, with a prescribed prairie burn in mid-December*

*Katie utilizing the services of the “brown bomber” in late December to complete some dumpster cleanup tasks in the old field station shop in late December*

*Janelle planting prairie wildflower seed along a new section of sidewalk near our Visitor Center in late December*

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!*

A Grand Old Burr Oak

Posted on December 2, 2020 by Brad Guhr

I spent time this fall with a grand old burr oak near Hesston along the Middle Emma Creek in McPherson County that caught my eye a few years ago. I introduce to you the Stucky Oak.

A Relic of Belonging

This tree is a stately burr oak (Quercus macrocarpa) estimated conservatively to be at least 200 years old. I find fascinating the remnants of vegetation around us that predate European settlement. Large open-grown burr oaks, like untilled prairies, are vestiges of a time shaped by climate and thousands of years of evolution.

For approximately 10,000 years since the last ice age, a warmer climate and the rain shadow effect of the Rocky Mountains have shaped the vegetation here. Plant communities existing at the location of Kansas have consisted mainly of grasslands tolerant of frequent fires initiated by lightning and Indigenous people and grazing by bison. Trees had a hard time getting established here when they were being eaten or burned to the ground every few years. Thus, prairies dominate the state of Kansas.

Oak Savannas of Eastern Kansas

As distance from the Rocky Mountains to the east increases along with average rainfall, trees more easily establish. An ecotone identified as oak savanna (prairie with scattered open-grown oaks) marks the transition from prairies of the Great Plains to the forests of the eastern states. Burr oak was the most dominant tree in this Great Plains ecotone for reasons described below. For more information about oak savannas, click HERE.

*Oak savanna historical range (Credit: Guy R. McPherson, 1997)*

Burr oaks in the eastern portion of the Great Plains were more likely to be found along stream corridors and especially on the east and north side of streams. Here, trees could survive better in the moister, more humid micro-climates and had some protection from prairie fires typically pushed in a east and north direction by the prevailing southwesterly winds. Fires that reached these locations were less frequent and of lower intensity as they typically would be backing against the wind. The Stucky oak along with a number of other old burr oaks dot the Stucky property located in one of these refuge areas just above the east bank of the Middle Emma Creek.

This burr oak in the foreground (let’s call it the “Sibling Oak”) is much younger than the Stucky Oak (seen in background) but still very stately. It too could be a relic of the oak savanna ecosystem present here during pre-European settlement times.

Unique Adaptations

Open-grown burr oaks growing on the prairie certainly have a different growth pattern than trees growing in a forest. Forest-grown trees have to reach vertically as they compete with other trees for sunlight. Trees growing on the prairie don’t have to compete for light and thus more efficiently orient their branches horizontally as well as vertically to maximize photosynthesis.

*Old open-grown burr oaks are typically wider than they are tall (The Stucky Oak – Photo by Lamar Roth)*

A tree with a relatively more shallow and broad canopy, will allow more light to filter through its branches to the understory below. This unusual, mottled light micro-climate under burr oaks harbors unique assemblages of plants not specifically found in either prairies or forests. For more on the makeup of these rare plant communities, click HERE.

*Mottled sunlight penetrating through broad-reaching branches of the Stucky Oak*

Fallen burr oak leaves are large, thick, rigid, curled, and irregularly shaped which keeps them aloft, and dry in the litter layer. In the spring, this persistent fuel easily burns and carries fire. Fires under burr oaks are hot enough to kill competing tree species that might invade its space, but not as hot as a grassland fire carrying more intense heat that could kill the burr oak.

*Burr oak leaf and acorn litter at Dyck Arboretum*

The thick, corky bark of a burr oak helps protect the cambium layer from the intense heat that could kill the tree. This trait develops on the trunk and branches of burr oak after about 10 years of growth and helps the tree survive repeated burning. For more on the biological and ecological traits of burr oaks and oak savannas, click HERE.

Not Quite a State Champion

In 2019, I heard a presentation at the Kansas Native Plant Society Annual Meeting about the Champion Trees of Kansas Program. I’ve been curious how the Stucky Oak would stack up against the biggest trees in Kansas and recently got permission to take some measurements. Trees in the Program have a calculated point total based on the following formula: POINTS = trunk circumference in inches + height in feet + crown spread/4 in feet.

As you can see from the following table, the Stucky Oak fell short of the champion in St. George (near Manhattan) in total points. However, with a similar trunk circumference (diameter comparison is 5.6′ vs 6.5′) and larger canopy spread, the Stucky oak is only hurt in this scoring by its shorter stature. Take into consideration that a tree east of Manhattan has benefitted from more rainfall over its life and grown faster than the Stucky Oak. When doing so, it is not inconceivable to think that the Stucky Oak may indeed be an older tree.

A Sense of Place

For most houses we know, the choices of vegetation for landscaping are chosen by the people tending the home. The Stucky house location, I am guessing, was chosen because of the vegetation that already existed.

Matt Stucky is the third generation in his family that has lived in this house that has enjoyed this location and made memories here. He’s a farmer and land steward and when talking with him, you immediately sense the affinity he has for this tree. You can tell that he enjoys the thought that his kids swing under the shade of this oak and throw acorns at each other the way he did as a kid and the way his dad probably did too.

*The farm name shows pride in a sense of place*

Matt fondly told me the story of an elderly couple from Oklahoma that stopped by some years ago to say they got married in their 20s under the giant oak in his yard. They were descendants of the original Classen Mennonite family that settled in the area in 1874. The couple showed Matt an old photo of the occasion. The tree in the photo looked basically the same as it does now. The couple returned many summers thereafter to sit in the shade of the oak for an afternoon.

History Transcending to the Future

The thought of natural phenomena that transcend generations of people and time move me. Whether it is seeing the same constellations in the skies above known to earth’s life forms since the beginning of time, stewarding prairies that have provided sustenance to residents of the Great Plains for thousands of years before me, or paying homage to an old tree known by families of Indigenous as well as European cultures, I find such things to be very powerful.

*Burr oak through the seasons (Partners in Place, LLC)*

Equally as powerful for me is our responsibility to carry these stories forward. I challenge you to make a connection to stories related to the nightly traverse of Orion across the winter night sky, how a bison kill for the Quivira Indians of Kansas was like a visit to the grocery and hardware stores today, and how an oak can enhance the biodiversity of your home landscape. Embrace these connections and pass them along to the next generation.

With this spirit in mind, my friend, Lorna Harder, and I collected acorns from the Stucky Oak and hope to raise burr oak progeny. We would like to share these young trees with teachers who participate in our Earth Partnership for Schools Program and members who attend our plant sales.

The quote from Caecilius Statius, 220-168 B.C. goes “We plant trees not for ourselves, but for the future generations.” I think you know now what species I would choose.

“This oak tree and me, we’re made of the same stuff.”
