How to be a Good Steward? Start with One Thing

Posted on by Scott Vogt

Over the past year, we have been digging deeper into “Why” the Arboretum exists.  There have been some lengthy conversations about events, classes, native plants, and relationships between people, plants and the land.  One of the questions we kept coming back to was “What can one person do?”  This idea that people change their perspective, build relationships, and/or develop empathy for the land one decision or choice at a time is an important concept for us to consider.  So with that in mind, what is one thing you can do today to make our environment more sustainable?

These are just a few things we can change that will have a positive impact.  There are hundreds more that are specific to your lives.  Start with one thing.

  • Ride your bike or walk to the store.
  • Convert a portion of your lawn to native plants.

  • Plant a vegetable garden each year.
  • Turn the lights off when you leave the room
  • Pay attention to how much water you use both in your home and in your yard.
  • Recycle, recycle, recycle.
  • Create a compost pile and use the compost in your garden.
  • Maintain your car and properly inflate your tires.
  • Use LED bulbs in your home.

  • Make sure your house has the appropriate amount of insulation.
  • Realize you can make a difference.

We all have choices to make when it comes to helping the planet, but I believe environmental stewardship starts at home.  If we choose to manage what we have in a way that saves us money and limits the negative impacts on the land, it is a win/win situation.  This is my epiphany – small incremental changes in my lifestyle will do something good for the environment.  I could always do more, but it starts to move the needle in a positive direction.

Maybe you are somewhat like me and find changing your behavior difficult, or you think stewardship is for someone else. That is not true.  Small changes in the things we do combined with thousands of others making positive choices can make a profound difference in the long run.  Don’t think of it as a compromise, but rather an investment in the future that allows future generations to live the same lives we now enjoy.

Start with one thing.

Be an Advocate for the Prairie

Posted on by Katie Schmidt

At Dyck Arboretum, we focus a lot of our energy on spreading knowledge and appreciation for the prairie. We love Kansas’s natural landscape and we are alarmed by how little native prairie is left intact. The prairie needs more advocates – people who will stand up for its preservation and defend its value to native wildlife and community health. Most of our direct efforts target land owners – people who can plant native prairie gardens and landscapes at their home or school. But these are not the only people who can make a difference! Here are a few ways you can be a prairie advocate even if you aren’t able to plant a prairie of your own:

Community Involvement

I enjoy attending my local city council meetings to keep tabs on what is happening in the community, especially in regards to environmental issues. Most city council meetings have a citizen comment session at the beginning or end of every meeting. This is the perfect platform to express your thoughts on community green spaces, roadside prairie preservation and responsible neighborhood development. Letting your local government know you want to see more natural prairie in and around the city could inspire big changes!

Encouraging your city to adopt sustainable land management policies can create pollinator habitat, help clean stormwater run off, absorb carbon pollution from the air, and much more! Carpenter Bee on Purple Prairie Clover (Dalea Purpurea)

Volunteerism

We say it all the time, but it deserves repeating — Dyck Arboretum couldn’t do what we do without volunteers. If you are passionate about prairie preservation and live in the area, consider volunteering for us! Here at the Arb, volunteers do everything from mow lawns and pull weeds to answer phones and process memberships. When you give your time to an organization, you free up the staff to focus on the heart of its mission and widen its impact. Search VolunteerKansas.org to find a place near you to volunteer your time and advocate for native landscaping, environmental education or sustainable agriculture.

Volunteers often help out on the grounds, planting new flower beds and maintaining old ones. They keep the Arboretum looking beautifully managed!

Membership

Lastly, if you don’t have lots of time in your schedule to attend community meetings or volunteer somewhere, don’t fret. The simple purchase of a membership to an organization you support can make a big difference. The Dyck Arboretum, and other non-profit organizations like us, depend on memberships as a large portion of our budget. Membership gifts also support our programming and events. We use membership numbers to gauge whether our message resonates with the public. It is always so encouraging to see that number grow, one membership at a time! Becoming a member tells us that you support the work we are doing and that you want us to keep it going. If that is how you feel about Dyck Arboretum, become a member and a prairie advocate here.

How to Beautify Your Home Habitat Garden This Fall

Posted on by Scott Vogt

I have said over the years that fall is a great time to plant just about anything.  I will not go into why fall is an ideal time to plant because you can read it here.  Whether you are creating a “new front yard” without turf grass or just supplementing your existing landscape, you will be rewarded in spring with healthier, heartier and well rooted plants that jump out of the ground.  The new fledgling plants you get from our fall FloraKansas Native Plant Festival will create a habitat garden that will be beneficial and attractive to wildlife as early as next spring.

The “New Front Lawn”

People are increasingly aware that the traditional front lawn is only marginally beneficial to wildlife compared to a habitat planting with wildflowers, grasses and shrubs.  This is an important paradigm shift as we think critically about how our landscapes can improve habitat loss.  By replacing small sections of turf with deep rooted plants, you reduce the need for water, create islands that wildlife, including pollinators, can use while increasing the overall aesthetics of your home.  This alternative to the traditional lawn starts with a thoughtful design followed by the removal of the turf you want to transition to native plants.  The area needs to be free of vegetation and problematic weeds.  Think about how you will be viewing your new landscape (from the kitchen window or from the street or both).  This process will help you lay out and stage your plants.

 

 

This gentleman is defining the new garden with a garden hose. Over the next year, he will dig up the grass and plant potatoes in the area while continuing to dig up any sprouting bermuda grass. It is a slow process, but he is able to develop a new garden without spraying. He gets nice potatoes too. A year later the area is ready for native plants.

Just a few additions

Fall is a great time to fill in some holes that have developed this summer.  Here at the Arboretum, the landscape is constantly changing.  As the landscape evolves and matures, new plants are added that complement the existing landscape.  I like to ask the question, “What is missing?” Do I need some structure plants, or wildflowers that bloom at a specific time? Do I need plants that can withstand a certain environmental condition unique to the site?  Asking these questions now provides you an exciting opportunity to add just the right plant(s) to round out your yard and help develop habitat.

Blank slate

I have done several designs this year and most are starting with new gardens. By starting from scratch, you have so many options available to you.  Homeowners want to make the switch and establish an alternative landscape.  Plan your garden, choose plants that fit your site, and get them established properly.  If you are not ready to plant the entire area this fall, I recommend getting the bones of the garden established.  Plant a cluster of grasses along the foundation of your home, a few shrubs in the center of the design, or a grouping of wildflowers along the perimeter. This will make it easier to fill in the holes and visualize the mature landscape next spring.

New garden ready for planting

Selecting plants with wildlife value and natural beauty will transform your landscape from dull and drab to dynamic and beneficial.  To see dragonflies, monarchs, other pollinators and birds being supported by your landscape is an inspiring experience.  Offering an attractive mix of drought tolerant plants will create the habitat these creatures seek to inhabit and use it.  Diversity of plants attracts a diversity of wildlife. Your garden can be part of the solution as we work to find balance in the world around us.

Habitat creation – the ultimate goal of any home landscape!

Let’s Talk about Mulch

Posted on by Scott Vogt

It is no secret that mulch is great for the landscape.  There are so many benefits when you add mulch around your plants.  Mulch is a great insulator, because it modifies the soil temperature.  It reduces erosion, prevent weeds from germinating, retains soil moisture, provides a buffer between equipment and the trunks and stems, and increases the aesthetics of the overall landscape. As you add mulch to your garden, here are some things to know:

How much mulch is enough?

Mulching is not an exact science, but as a general rule, we try to apply 2-3 inches of mulch consistently throughout the landscape.  This depth of mulch will control weeds by decreasing sunlight exposure, which prohibits seeds in the soil from to germinating.  More than three inches of mulch seals off the soil and suffocates your plants.  It is extremely important that the plants are able to get the oxygen they need.  Spread the mulch evenly and don’t build a mulch volcano around the base of the tree.  Since mulch decomposes slowly, it is good to periodically check the depth and add some as needed.

Nicely mulched new planting

What is the best way to mulch?

We start by laying out a garden hose, which allows you to visualize the curves and width of a bed.  You can either spray the area inside the hose or dig up the vegetation and let it slowly die.  When the area is cleaned up, we begin applying the mulch and leveling it to the desired depth.  Keep in mind that too much mulch will encourage growth of the roots into the mulch, where it will be susceptible to freeze damage.  The ideal 2 to 3 inch depth of mulch will keep the roots in the soil.

When is the best time to mulch?

We are mulching throughout the year, but direct most of our efforts in the spring or fall.  As we clean up our display beds in the spring, it is always a good time to freshen up the mulch, too.  At this time of year, soil temperatures are beginning to warm and a new layer of mulch will slow down the warming process.  A new layer of mulch will also cover seeds that may have landed in the mulch and covering them now will prevent germination.  We mulch anytime a new tree or shrub is planted.  This practice will keep the soil cooler, help retain moisture longer and insulate new roots from the cold weather. Some thicker mulch areas may benefit from being fluffed from time to time.  Simply take a rake and loosen up the top few inches of the mulch.

What type of mulch is best?

We use whatever is available to us.  Mulch is not cheap, so we use chippings from the tree trimming service.  We have used semi loads of hardwood mulch, which is expensive. It is not as important what you use, but how much you use.  Even free mulch can look attractive and function just like the most expensive mulch.  For sloped areas, the larger and heavier mulch works the best.  It is not as susceptible to runoff or wind displacement.  Smaller or finer mulch decomposes quicker too.  The bottom line is use what is available to you.

Can I use plants as mulch?

In the book Planting in a Post-Wild World: Designing Plant Communities for Resilient Landscapes, Thomas Rainer and Claudia West develop the ideas of layering plants.  There are usually at least three distinct layers of plants: the upper layer filled with taller structural plants used to frame and punctuate the landscape, the middle layer filled with ornamental flowering plants and the ground level that weaves the other layers together and shades the soil, which controls weeds.  These layers mimic natural plant communities and each layer is important for the health of the plants.  A collection of plants living in community can be extremely drought tolerant and water-thrifty.

A few final thoughts:

Purchase a heavy duty mulching fork and stiff garden rake for leveling.

Essential mulching tools: Silage fork and stiff leaf rake

Insects can be a problem in mulch, so keep it away from the foundation of your house and base of the plants.  Termites generally like larger pieces of wood but can even live in the finer mulch, especially if it is too thick.

Landscape fabric under mulch is something we avoid.  It only keeps weeds out for the first few years and then the decomposing mulch turns into compost, which is ideal seed bed for weeds.  It is also hard to transplant into it and often suffocates the soil.  We have purged the Arboretum of just about all landscape fabric.  Save your money and buy more plants.

You can use rock as a mulch, but don’t buy the recycled rubber mulch.  The rubber mulch may last forever but it does nothing great for the soil or the plants around it.  In fact, the compounds and residues that leach over time may do more harm than good.

Happy Mulching!

Five simple ways you can make a difference for wildlife

Posted on by Scott Vogt

In the grand scheme of things, we have a tremendous capacity to impact our surroundings for good or bad.  A few changes in how we approach and look at our landscapes can make a real difference to the future of the wildlife we enjoy and care about.  Here are five ways you can positively impact wildlife and create something you enjoy too.

Increase vertical layering

Having tiers of plants from the largest trees to the lowest grass and everything in between is the perfect habitat for wildlife. Plants of varying heights and forms create interest in the garden, but more importantly these diverse plants provide food, shelter, and nesting sites for beneficial insects, birds, small mammals, and other wildlife. The use of native plants will only attract more wildlife.

Provide water

Water is an essential part of any diverse wildlife habitat. Just like us, wildlife need water for their survival. It doesn’t have to be anything fancy. A birdbath, small pond or bubbling fountain will be like a magnet for all sorts of wildlife. Besides, there is something soothing about the sound of water moving.  We may need it for our own healing.

Reduce your lawn

Invariably as we have done insect sweeps over lawns versus prairies, we always catch more insects and pollinators in the prairie. It makes perfect sense. The shortness of the lawn and lack of diversity of plants repel rather than attract more insects and birds to the areas that are more diverse.

Limit the use of chemicals

Obviously, chemicals were created to eradicate pests. However, chemicals adversely affect not just one pest but also many non-targeted species. In addition, the chemical residue can remain active for an extended period of time, lengthening the impact. Here at the Arboretum, we use chemicals sparingly and as a last resort. A diverse planting attracts a host of insects, including predator insects and birds that feed on the problem pest.  A pristine landscape with whole leaves and little insect activity is not natural. Some pests are inevitable and are usually controlled by other wildlife.  It is important to wait for the natural processes to take place.

Become a citizen scientist or naturalist. Be aware of wildlife and its needs.

The more you know about the wildlife in your landscape, the more you will understand what they need for their survival.  Knowledge is power. Monitor what is happening in your yard. Create habitat by establishing trees, shrubs, grasses and wildflowers that attract a host of diverse wildlife.  The awe that many of these critters invoke naturally creates within us a desire to learn more about them.

The most important thing to remember is that you can make a difference. Even a few small steps over the next few years will have a positive impact. While it might not seem like your small space is that important, imagine your landscape connected to hundreds of other patchwork gardens throughout the town. These gardens will make a difference, over time, on the wildlife we seek to help. No small change is too trivial—so pick one of these ideas today and take action!

Plant Profile: Mountain Mint

Posted on by Katie Schmidt

Mountain mint plants are underused in the landscape. With dainty white blooms, a clumping habit and tons of genera to choose from, mountain mints (Pycnanthemum sp.) can fit in any style of garden. P. tenuifolium, P. virginiana, P. flexuosum, and P. muticum are the species most often available for purchase at FloraKansas. I always wonder why they don’t fly off the greenhouse bench at our sales – it must be because people don’t know enough about them!

Virginia mountain mint is an attractive species, in the garden or out in the prairie!

Piqued for Pycnanthemum

All species in the Pycnanthemum (pick-nan-the-mum) genus are native to North America. They are in the mint family, so the leaves have that delicious, refreshing mint aroma when crushed. They spread via rhizomes and left unchecked can cover ground fast, though not quite as aggressively as other members of mint family. The blooms attract a wide array of pollinators. It is a special favorite among bees, flies and wasps, though swallowtails, grey hairstreaks, buckeyes and skippers often visit them as well. Ironically, mountain mints most often thrive in meadows and grassy prairies, not in alpine situations.

So Many Mints, So Little Time

There are lots of varieties of mountain mint out there, but the various species can be tricky to tell apart for the layperson. The blooms are all very similar: round and clustered, whitish to light purple, with spots. However, the leaves do have distinct shapes that vary between species. My favorites are the thin leaved species such as P. virginiana and P. tenuifolium.

P. muticum is easily recognized by its teardrop-shaped leaves, much wider than the other species. Found from Texas and Missouri all the way to Maine, this native grows in moist meadows and woodland areas. Like all mountain mints, it likes full sun to part sun and average soil moisture.

P. flexuosum is not native to Kansas, but still grows well here. This plant grows wild in the Carolinas, Florida, and west to  Mississippi and Alabama. Thick, lance-shaped leaves set it apart from the others. As New Moon Nursery describes it, “Pycnanthemum flexuosum is an aromatic perennial wildflower.  This mint relative bears oval toothed leaves on strong square stems.  In summer, plants are topped by dense frizzy ball-like clusters of tiny white to lavender tubular flowers.”

Mountain mints are easy to care for and will spread fast in the garden, filling in the gaps and looking lush all season long. The densely clustered flowers of this pollinator powerhouse will add beauty and wildlife value to your landscape. Be sure to ask for mountain mint at the next FloraKansas!

Plant Profile: Rattlesnake Master (Eryngium yuccifolium)

Posted on by Scott Vogt

There are quite a few native wildflowers that everyone knows – coneflowers, gayfeathers, prairie clovers, evening primrose and so on. But when I tell folks to try some rattlesnake master, Eryngium yuccifolium, I get the blank stare, or the proverbial crickets in the room sound. What does that do? What does that look like?  True, it is one of the lesser known wildflowers, but I contend that it is just as attractive as some of the common wildflowers.

Rattlesnake master, Eryngium yuccifolium, gets its name from the belief that the roots have the ability to heal snake bites. In today’s world, I would stick to the true antidotes. Often the root was dried and used in bitter teas as a supposed cure for maladies such as venereal disease, liver problems, impotence, expelling worms and to induce vomiting. It makes me thankful for modern medicine, but back in the 18th and 19th centuries many herbs from the prairie were used to cure a variety of ailments because they had nothing else.

This unique wildflower’s scientific name comes from the close resemblance the leaves have with a yucca plant. The sword-like leaves have soft tiny barbs along the edges that make it easily recognizable. In the summer, the white thistle-like flowers develop atop the stout upright stems. Even though it looks like a thistle, it is actually a member of the carrot/parsley family. Rattlesnake master ultimately reaches about three to four feet tall with a spread of one to two feet. I like to combine them in groups of three in the middle to back of the flower bed.

In the landscape or in a prairie, it is quite a striking plant. The grey-green foliage and one inch diameter flower heads make it stand out in the garden as an accent plant. The flowers slowly dry and become yellow-brown later in fall and into the winter. The stalks are sturdy and remain well into winter, providing interest in the landscape. We have even used them in dried flower arrangements.

Plant them in full sun or part shade for best growth. They are quite adaptable, but prefer a medium to dry soil. I have planted in spring and fall with easy establishment either time of the year. This is a plant that should be used more in roadside plantings, prairie restorations, prairie landscape settings, and in your wildflower garden.

You may never need a rattlesnake master for a snake bite, but you do need some rattlesnake master in your garden. Its attractive appearance and resilient beauty are outstanding. Plus, pollinators love it too.  You may have just found your next favorite plant.

Eco-Friendly Lawn Replacement

Posted on by Katie Schmidt

Anyone who has ever been in the car with me, driving through a city or suburban area, has been subject to my rant about turfgrass. My friends and family have come to know this argument by heart. I love a nice green lawn as much as the next person, but with pollinator habitat disappearing by the acre and freshwater around the world becoming ever more precious, I can’t help but be a little critical of them. The fact is, a nonnative grass monoculture (area of only one species of plant) of bluegrass or fescue is something of a pollinator desert – offering no larval host plants or flowering food sources. And beyond that, they can take a lot of chemical and water input to keep them green and weed free. There are so many more interesting, attractive and ecologically friendly options for lawn replacement!

So Many Reasons, So Little Time

Between homeowner yards, business fronts, and miles of narrow hellstrips along city streets, our love affair with turfgrass runs inexplicably deep. And we have much too much of it here in Kansas – in 2011, Kansas had 495,000 acres of lawn, slightly more than the acreage of wheat but less than our acreage of corn. But there are so many good reasons to rethink our grass obsession and transition to more productive landscapes:

  • native grasses/garden provide larval host plants and habitat for overwintering insects
  • native plants produce seeds and berries for birds
  • deep roots of native plants enrich soil and are resilient against drought
  • dense garden spaces provide carbon sequestration and help to cool the air

I won’t tell you transitioning from a lawn to a prairie garden is easy. It takes lots of time and a fair bit of labor. I see it as trading one type of work for another. Instead of mowing every week, you will mow it down once a year. You save money on fertilizers and herbicides, but you spend time planting and weeding. I find gardening much more enjoyable work than traditional ‘lawn care’, and all the less tedious because I know the work is part of responsible resource use and providing habitat.

Wild ginger (Asarum canadense) makes a great substitute for turfgrass in shady areas. It creeps along the ground and has small cupped flowers. https://www.wildflower.org/gallery/result.php?id_image=21411.

But even I am not a purist here; I will always have a little bit of grass lawn in my landscape. I have a dog who loves to play frisbee and roll in the grass, so that space gets well used. Additionally, you can use small areas of green grass to give the eye a rest in an otherwise diverse and colorful landscape. There is a whole spectrum of choices: you can go gung-ho and convert all your grassy areas to garden spaces, or you can simply commit to decreasing your square footage of turfgrass while still keeping certain areas for recreation and aesthetics.

Go All In

If you are ready to swear off weekly mowing, regular applications of fertilizer, aeration, and all the other tasks that lead to a perfectly green lawn, consider a total transformation. Who says a garden has to be relegated to a small corner of the back yard? Make your lawn into a pollinator paradise with flowering natives. To keep the space looking organized and intentional, plant in masses or clumps. Following a landscape plan that draws the eye through the landscape with repeated colors and shapes also helps.

Starting Small

Perhaps you, like me, still need some green lawn for your dog or space for a game of horseshoes. There are lots of ways you can decrease your ecological impact and create habitat without giving up your grass completely. Wide grassy pathways with curved edges create a fun, natural looking space that still provides room to play. Alternatively, think about areas of your landscape that are already divided up – do you have a sidewalk or fence that separates one part of your yard from this other? Commit to converting on of those spaces to native garden while the other can remain grass. This method allows you to learn as you go instead of being overwhelmed by an entire yard full of new plant material.

Internationally, people are leaning towards less grass and more flowers! This garden in the Czech Republic is a great example of how to use small areas of grass to keep garden beds contained.  https://commons.wikimedia.org/wiki/File:7.d%C3%ADl_html_4ae5ed86.jpg

If you are thinking of making changes to your yard, big or small, Dyck Arboretum can provide landscape designs and choose native species that will thrive. The birds and butterflies you attract will be happy to see a yard full of food and color!

What is the Key to Native Plant Happiness?

Posted on by Scott Vogt

One of the questions we get every year at the FloraKansas Native Plant Festival, is “why didn’t my ___ come back this year?” It is a great question. Every year at the Arboretum, we ask the same question with some of the plants we establish and want to grow. I wish there was a right answer for every situation and every scenario, but every landscape is unique. Here’s the hard truth that many gardeners don’t often want to hear: the key to native plant happiness lies in identifying this uniqueness and finding the right plants for your plot.

Match Plants to Your Site

Your landscape is a micro-climate all its own. The soil, sun exposure, orientation to your house, root competition from trees, and many other factors make your garden special. Even your neighbor overwatering their lawn can impact what plants grow best in your scene.  There are hundreds of factors that relate to the happiness of your plants and whether or not they will thrive.

The most critical step when establishing your native plant garden is matching the plants with your site. Sometimes I want to try a certain plant in a certain spot that has no business being planted there. I have done it too many times to mention and the result is always the same. I am left holding the hand of a struggling plant that would be much happier someplace else. In the end, I either move it or lose it.

Do Your Homework

If we are honest, I think we have all planted before preparing. The wilting plant in the flower bed is a constant reminder to me that I didn’t do my homework.  Look at your landscape.  Is it sunny or in the shade?  Is the soil clay or sand?

Become familiar with prairie plants that grow in similar situations and evaluate the elements that will impact their survival. Choose plants that will thrive in the micro-climate of your yard.  Sun-loving native plants need at least 6 hours of direct sunlight to grow happily. If your flower bed receives less than 6 hours of sun, look at more shade-loving natives.

A thriving landscape begins with matching plants to your one-of-a-kind area. For a lower-maintenance garden, choose plants that occur in the same or similar prairie climates.  Anytime you stray too far off, the plants don’t flourish and they require more effort to keep alive.  Planting a swamp milkweed on a dry hill or a Missouri evening primrose in a bog will never work.

Learn From Your Mistakes

Good gardeners have lost their share of plants over the years, but what makes them good gardeners is that they learn from their mistakes. With lots of trial and error under their belts, they/we should make better choices…in theory at least.

Other design elements such as succession of bloom, patterns, year round interest, heights, and visual elements become less important when your plant is unhappy in its current location. You must get the right plants in the right place and the other elements will come much easier. A healthy garden begins with a connection to your landscape personally. As you watch and learn  what your landscape needs and what it can sustain, you will be able to link the appropriate plants to the location. This important step in the design process allows you to spend more time enjoying and less time “working” in your garden.  We all want that from our gardens.

Just one more thing…

Sometimes plants, through no fault of our own, defy all of the above-mentioned rules and simply don’t return. Even in the prairie, plants are ephemeral and rely on self-seeding to continue to grow in an area.  As you become more familiar with native plants (and I’m still learning too), you will be able to identify these species.  It is their nature to be short lived. True native coneflowers have this characteristic.  They are worth planting, but may need to be supplemented with new plants from time to time to keep the area full.

Imposter Plants: What it Means to Be Native, Part II

Posted on by Katie Schmidt

This post is the second installment of the Imposter Plants series. In the first post I discussed the differences between native and adaptable, while also trying to clear up the confusing descriptor ‘naturalized’. Here I will dig into the details on what it means to be invasive, noxious, weedy, alien or exotic.

Garden Bullies

On February 3rd 1999, President Bill Clinton signed an executive order that was meant to protect the US from imminent invasion – plant invasion! Non-native plants that become out of control can affect agriculture, ecology, endangered species and human health, and the President was right to be concerned.

There are many definitions for what an invasive plant is, and some are contradictory. Here is my simplified aggregation of the most prevalent ones on the web: a plant is invasive if it is non-native to the region and spreads aggressively enough to displace native plant populations. These plants are not only bullies in the home landscape, they can easily escape into the wild and begin reproducing. Harkening back to the previous post, non-native plants that reproduce on their own in the wild are ‘naturalized’, but the important distinction is that naturalized plants do not degrade habitat and cannot outcompete natives for nutrients, water or sunlight. Invasive plants certainly do, often causing damage to the local flora and fauna.

 

Field bindweed (Convolvulus arvensis) is an invasive plant as well as a noxious weed. Brought here from Eurasia, it quickly adapted to the North American climate and is pervasive enough to choke out native plants and hinder agriculture.

 

Prairie Dock (Silphium terebinthinaceum) is a beautiful native species, but spreads aggressively and can take over your garden. Even so, this is not technically an invasive plant.

Weedy and Noxious

I truly despise the term ‘weedy’. Not only is it vague, it is completely subjective. One person’s weedy plant is another’s favorite flower! The true definition of a weed is merely ‘a plant out of place’; a weed can be any plant, native or non-native, that does not belong in its current place. We use this word to describe the behavior of the plant more than the plant itself. Does it pop up everywhere? Does it come back even after you pull it? Well, a gardener might call this plant a weed, even if they once planted it there themselves. But since it only describes the action of the plant and not the legal status or origins, this word doesn’t hold much weight with me.

Brad Guhr captured this delaware skipper (Anatrytone logan) enjoying the bloom of a native thistle, Cirsium altissimum. People often confuse these with non-native thistles classified as noxious weeds. Our native tall thistle is important to pollinators.

 

Regal fritillary on native tall thistle. You can identify native thistles from the noxious by their leaves – Cirsium altissimum leaves are green above white and woolly underneath. To learn all the details on native and non-native thistles from Brad Guhr, click here.

A noxious weed is a different story. Noxious is a legal term and its definition is closely tied to agriculture. Per the 1974 Federal Noxious Weed Act, “a plant that directly or indirectly injures crops, other useful plants, livestock, poultry or other interests of agriculture, or the fish or wildlife resources of the United States” is considered noxious. Confusingly, native plants can be noxious weeds. A noxious weed grows aggressively, multiplies quickly without natural controls (such as herbivory) and threatens agriculture. The USDA regulates these plants and monitors their populations.

Extraterrestrial and Just Plain Weird

Lastly, let’s tackle a few terms that arise occasionally to confuse and befuddle. Though we call some plants ‘alien’, this doesn’t mean they have invaded from Mars. We can use this term interchangeably with ‘non-native’; both mean that a given plant is not naturally found in the area. You may also hear a plant called ‘exotic’. What comes to mind might be tropical, rare, or expensive specimens, but in fact this is just another name for a non-native plant. An exotic plant has origins in another place, perhaps on another continent. Exotic and alien are often bundled together with other terminology – exotic introduced (a non-native plant brought to a new place), an alien invasive (a non-native plant that harms local ecosystems), an exotic naturalizer (a non-native that reproduces in the wild but doesn’t cause major problems) … and so on!

Tamarix is an exotic species native to Eurasia and Africa, but is now spreading aggressively over many parts of the US. So prevalent in some areas, it can lower the water table and deposit large amounts of salt in the soil.

Whether a plant is invasive or naturalizing, native or weedy, can often change based on who you are talking to. Some of these terms overlap in definition, leaving much to argue about. There is even scientific interest in finding a new way to classify these plants to help dispel the confusion. By educating yourself on correct classifications, you can help friends and neighbors understand why they shouldn’t plant invasives that ruin our wilderness. You can also help at our FloraKansas Plant Festival, teaching others that native plants are not just pretty ‘weeds’.
