Aromatic Aster

Posted on October 23, 2024 by Brad Guhr

One of my favorite prairie wildflower species has to be aromatic aster (Symphyotrichum oblongifolium). Aromatic asters are hardy, drought-tolerant forbs that bloom toward the end of the growing season. Their leaves have an herbal scent when crushed. Aster species are host plants for caterpillars of butterflies including painted ladies, pearl crescents, and silvery checkerspots as well as many species of moths. In the late summer and fall, aromatic aster flowers delight the human need for color and provide nectar for many insects, most notably, butterflies, bees, wasps, flies and beetles.

*Aromatic aster var. ‘Raydon’s Favorite’*

According to Mike Haddock at Kansas Wildflowers and Grasses, aromatic aster is found across almost the entire state of Kansas on dry, open prairies. In our Dyck Arboretum reconstructed prairie, aromatic aster (seed collected from the Smoky Hills ~30 miles north of Hesston) is just about finished flowering. Its purple hues popped a couple of weeks ago among the reddish-brown colors of senescing warm-season grasses.

A Star in the Prairie Garden

In our native plant gardens, aromatic aster is the star of a show that we have been looking forward to all growing season. Aromatic aster fills garden spaces between other plants nicely where its dense, low 1′-2′ foliage crowds out weeds and lends above-ground support to neighboring plants. But its late-season flowers are the main reason that this species is a dominant part of our featured Butterfly Garden.

While I enjoy observing all prairie flowers throughout the growing season and the pollinators they attract, aromatic asters just seem to take the human entertainment value to a higher level. Given the high number of flowers on each plant and the lack of anything else blooming this time of the year, this species usually seems to put on the greatest show of the year as it plays host to a busy array of insect pollinators.

The two varieties of aromatic aster in our Butterfly Garden are ‘October Skies’ and ‘Raydon’s Favorite’. They bloom at different times and in nice succession for a long season of attracting pollinators. I seem to usually observe the former blooming from late September to mid October and the latter from mid October to early November.

Whether I’m walking with elementary schoolers, college students or retired master gardeners, this Butterfly Garden spot on a sunny afternoon is always a regular stop. The flowering spectacle by aromatic aster in this time of the year is one of my favorite flower/pollinator interactions in the prairie garden.

When trying to capture the jaw-dropping wow factor of a landscape scene like the Flint Hills or a Kansas sunset, a photo or video never conveys the inspiring scene I want. Nevertheless, here is a video of the super busy pollinator scene I witnessed yesterday (10/22/24).

13 Butterfly Species Observed

The butterflies I observed nectaring on the flowers of aromatic aster var. ‘Raydon’s Favorite’ yesterday included the following species: checkered white, sachem, common checkered skipper, fiery skipper, dainty sulphur, clouded sulphur, orange sulphur, eastern tailed blue, common buckeye, monarch, pearl crescent, Melissa blue, and American lady (not all species were visible in the video). Various species of bees (audibly busy), flies, beetles and moths were also abundant.

Stop by and see our Butterfly Garden before the aromatic aster finishes its show in the next week or two. Better yet, add different varieties of aromatic aster to a sunny spot in your landscape where you can enjoy a similar show for years to come.

The Edible Landscape

Posted on March 13, 2024 by Katie Schmidt

I am a big fan of a landscape that is functional as well as beautiful. Functionality might mean wildlife and pollinator attraction, water absorbing (rain garden) or water conserving (xeriscaping). But it can also mean incorporating human food plants into your perennial garden. This not only provides a healthy snack, but it encourages more interaction and participation. What is the point of a beautiful landscape if you aren’t out enjoying it?

Here is a small preview of some of the plants I discuss in my Native Plant School class, now available on our YouTube channel, all about landscaping with edible plants.

If this topic fires you up, stop by our gift shop to grab a copy of Kelly Kindscher’s Edible Wild Plants of the Prairie, a wonderful plant guide and exploration of ethnobotany on the Great Plains.

Elderberry (Sambucus canadensis)

A personal favorite of mine, Elderberry is as beautiful as it is nutritious. This plant will love a low spot in the yard where water tends to collect after rains, or an area with poor drainage. It can reach 8ft tall, putting on an impressive show in late spring when covered with massive white flower clusters. Berries ripen in July, a perfect time to spend the hot afternoons in the kitchen making jams and syrups. I make a cold remedy from them that has never let me down!

Pawpaw (Asimina triloba)

Persimmon (left) and PawPaw (right) both produce delicious fruit.

Everything about pawpaw seems tropical. Surely this fruit cannot be native to hot, dry Kansas…yet it is! It is an easy growing plant that can grow in full sun or partial shade and tolerates alkaline soil. To get a good fruit set you should plant more than one; though they have both male and female flowers on a single tree they are not self-fertile. The fruit is worth it! A custard-like texture with the flavor of bananas and mangos, it is perfect for pies and homemade ice cream.

Bee Balm (Monarda fistulosa)

*Monarda fistulosa flower, photographed by Brad Guhr*

If you are short on garden space and can’t add a shrub or tree, never fear. Monarda fistulosa is a wonderful edible perennial much smaller in stature than the previous options. About 3ft by 3ft when happy and mature, the leaves of this plant make excellent tea, with a flavor reminiscent of the bergamot oil used in Earl Grey. It has a long history of medicinal use by indigenous North Americans, for everything from upper respiratory problems to sore feet. The flowers are also edible and add a citrusy, spicy punch to salads.

From persimmon to chokeberry, we have so many native plants to choose from to diversify our diets and add beauty to our home landscapes. Thanks to thousands of years of culinary experimentation by the tribes and nations of North America we have a rich ethnobotanical tradition to learn from, an example of how to learn about, appreciate and interact with food and flora.

The Importance of Diversifying Landscapes

Posted on November 1, 2023 by Scott Vogt

When you look at a virgin prairie (one that has never been tilled), you quickly discover a tremendous diversity of plants. Each square foot has many different species vying for sunlight, moisture, and space. Species change throughout the prairie as well from high to low, wet to dry, sun to shade, and vary even with soils. This diversity contributes significantly to the overall health and sustainability of the prairie landscape.

*Prairie Window Project in September 2017*. *Photo by Brad Guhr.*

One of the keys to successfully creating a prairie garden is including a diversity of plants suited to your site. Time of bloom and aesthetics are often considered first, but including variety is an essential element in the process too. It’s also important to think about diversifying trees and shrubs. Let’s look at some reasons why diversifying our home landscapes to include more species is so relevant.

A Diverse Landscape is a Resilient Landscape

While each landscape is different, they all face an array of environmental pressures, such as drought, floods, pests, and diseases. A diverse landscape is more adaptable and resilient, able to endure these environmental hazards. We have all seen shelter belts and monocultures decimated by drought, pests or disease-leaving large holes in the landscape. If you think about it, single species or similar species landscapes are vulnerable to eradication in ways that diverse landscapes are not.

A Diverse Landscape Attracts Diverse Wildlife

Building season long blooms benefits wildlife. Plants coming into bloom and going out of bloom mimics the prairie ecosystem. If you watch any prairie throughout the year, there are always a new set of plants blooming every few weeks throughout the growing season. Beyond building resilience, a diversity of plants attracts a diversity of pollinators and wildlife allowing them to complete their lifecycles. This is so crucial for their survival. Patchwork prairies can serve as harbors, offering food and shelter to a broad range of wildlife.

A Diverse Landscape is Visually Interesting

As I said earlier, often our first consideration when choosing plants is aesthetics or ornamental characteristics. I don’t want to downplay this step in the process, but I do want to encourage you to try many different types of plant species. By varying plant species, you provide visual interest, which adds character to your landscape. Some of the most inviting spaces have diverse colors, shapes, blooms, textures, layers, and heights of plants.

A Diverse Landscape is a Dynamic Plant Community

A diverse plant palette suited for your site can look formal, but it generally requires more effort on our part to keep it looking kempt. However, an informal planting can be just as attractive. It depends on your maintenance style and preference. No matter how you want your landscape to look over time, we must prioritize the careful selection and planting of diverse prairie species.

It can’t be overstated – diversifying landscapes in the urban setting is so important. Diversity in the plants you include in your landscape attracts diversity to your landscape. This thoughtful approach to design not only enhances the beauty of our gardens but also strengthens their resilience in the face of environmental challenges. It also promotes sustainability, conservation of natural resources, and enriches our experiences with nature.

Know Your Garden Priorities and Purpose

Posted on July 17, 2023 by Katie Schmidt

Portions of this article can also be found in our Summer 2023 issue of the Prairie Window Newsletter.

Having a summer intern here at the Arboretum is a lot of fun. Not only because I have someone to commiserate with when the temperatures are unbearable, or someone to laugh with when everything goes wrong, but also because they always ask “why?”

*The island garden here at the Arboretum features an evolving prairie planting from seed. We manage this area with annual prescribed burns.*

Why did we cut it by hand instead of mowing? Why did we move those leaves or add mulch? Why do we maintain this garden different from the next one?

The answers to these questions almost always center around priorities and purpose. To curate an Arboretum, we manipulate our natural environment in different ways, with goals in mind for each specific area.

Is the purpose of this garden to attract butterflies? Then we don’t do any trimming during peak caterpillar hatching time.
Are we hoping to encourage lightning bugs to nest here? Don’t rake away the leaf litter.
Is the goal of this space to be symmetrical, patterned, or have a certain color palette? Then we weed more frequently and stick closely to the original design.

Knowing your priorities and the purpose of a space easily guides your decisions.

*Plantings at our neighboring retirement community make use of drought tolerant plants with a more traditional approach to design.*

Evolving Priorities

Traditional landscaping has one job: to look pretty. We started creating ornamental gardens at castles and estates to signify wealth and create beauty. Several hundred years of horticulture practice have passed with little change. These human-centric values still have a stronghold on the landscaping industry. The typical shrubs, trees, and perennials installed around a newly built home in an American suburb are purely ornamental, with no relation to wildlife, climate, or geographic region.

Their purpose? Purely aesthetic. And so all the future decisions must serve that goal. Heavy chemical use to maintain the green lawn? Yes, to preserve the aesthetic. Constant trimming and shaping of shrubs? Yes, to make them look different from their natural shape. Overuse of water to keep non-native species green in a climate they did not evolve in? Of course. This is not a sustainable option, and at its worst is an outdated practice steeped in vanity and classism. Thankfully these priorities are beginning to shift to a more sustainable model of landscaping.

Find Your Purpose

Everybody has to decide for themselves, and for each unique space, what the purpose and priorities are. If the goal is to teach students about native plants, then we should prioritize plant labels. spacing, and good organization in the garden. If the purpose is to increase habitat, then prioritize ecosystem function — high plant diversity, dense, layered planting, less structure.

This sign garden at Schowalter Villa’s Prairie Lakes begins to move in the direction of building plant communities by planting more densely, but still prioritizes traditional aesthetics over ecological function.

There is no “one way” to successfully use native plants. Some of our members are looking to decrease water usage, but keep their landscaping looking traditional and tidy. In this case, we might suggest using some cultivated varieties of natives that don’t spread or seed out much, but are very drought tolerant. For folks hoping to restore a prairie plot for conservation purposes, we would recommend straight species only and help them find an appropriate ratio of grasses and flower species native to their region, or even their county.

Liatris pycnostachya, or prairie blazing star

The plants chosen for each new project should be chosen with clear purpose in mind. A few years in, when you are adding new plants to the garden or making tough decisions, remembering your purpose and priorities will help keep you on track!

A big thanks to our grounds interns present and past, who have all asked excellent questions and contributed their talents to the Arboretum. You challenge us to always think critically about our priorities and purpose!

Seven Lessons I Have Learned About Native Plants

Posted on June 1, 2023 by Scott Vogt

Over the 26 years that I have been at the Arboretum, I have made my share of mistakes. Some examples include planting prairie dock in a formal garden design, starting a garden too fast, and/or not knowing my site. I had book knowledge about horticulture, but I had not learned much about native plants. Through trial and error – mostly error – I learned some hard lessons and even killed a few plants along the way. I am still learning, but here are seven lessons I believe are essential for a successful prairie garden.

1. Perennial and annual weed control

I have made this mistake too often. In a rush to plant, I don’t get problem weeds like bindweed and Bermudagrass under control before planting. I am still fighting this issue to this day in some of these landscape settings. However, when I take the time to properly eradicate these weeds, the overall long-term success of the garden increases and the work to maintain it decreases. A little work at the beginning will save you many headaches down the road.

2. Plants should match your site.

This is the most important principle to follow in developing a successful landscape. Take a critical look at the area you want to landscape with native plants. Is it sunny? It is shaded for part of the day? What type of soil do you have? Is there a microclimate? Is it exposed to wind? All these factors will guide you as you select plants for your site. This step requires some research and time as you familiarize yourself with the qualities and environmental needs of native plants.

3. Succession of Bloom

There are no Wave Petunias in the prairie. If you visit a prairie landscape like the Konza Prairie every two to three weeks throughout the year, you will observe plants beginning to bloom, in full bloom or going out of bloom. That is how you need to design your native landscape. Include plants that bloom in every season of the year and then strategically add grasses for movement and texture in the winter months. Take time to acquaint yourself with the life cycles of wildflowers and grasses.

4. Plan your garden for all seasons of the year

This lesson took the longest to learn, because it meant becoming familiar with the complete life cycle of each native plant. I needed to learn all about them – their bloom times, soil conditions they need to thrive, mature height and what they look like when not blooming, including seedheads and forms. Most of these characteristics had to be experienced over several years. That information is vital to planning and developing a prairie garden.

5. Be Patient

A prairie garden does not magically appear overnight. I know this goes counter to our “instant everything” culture, but prairie plants don’t work that way. It takes time for those transplants or seedlings to develop root systems that will sustain them during the dry periods of the year. I remember visiting a prairie reconstruction in Wisconsin several years ago. It had been established from seed 20 years earlier and the prairie manager said it was just then really maturing into a true prairie. I have found that if you are patient, you will be rewarded by beautiful, strong and adapted native plants.

6. Start Small

Planting too much too soon – I have made this mistake many times. My eyes get bigger than I can manage. I like too many of these native plants and rather than working at a project in stages, I plant the whole area. I then spend the rest of the summer maintaining a planting that is too big for the time I can give it. It has a tendency to get out of hand in a hurry if I don’t keep up with it on at least a weekly basis. Plant an area that you can handle with your schedule.

7. Remember Why!

Most times we create something for our own enjoyment. A properly designed native garden can be very attractive to you aesthetically. What we often forget, but are quickly reminded of, is that native plants attract many different pollinators and other wildlife to our landscapes. If you plant them they will come.

Pollinators and wildflowers have a symbiotic relationship. Pollinators seek out the wildflowers they need and utilize them throughout the year. Monarch populations are declining. They need milkweed, and since we have milkweed in the Arboretum, they show up. Also, just like the monarchs, songbird populations are declining. They need prairie habitat for survival along with wildflower seeds to feed overwintering birds.

Obviously I have not figured everything out. Learn from my mistakes and maybe a few of your own. Gardening is not an exact science. What works for you may not work for me. Your site may be totally different from mine. The key is to keep learning. Try plants you believe will work in your landscape.

Besides learning lessons the hard way remember to connect with your WHY! The “WHY we do something” gets lost in the tasks of creating something new. I need to be reminded “WHY” from time to time to reset my focus. We each have our own unique perspective and motivation, but reconnecting with your “WHY” will move you ever closer to your native plant gardening goals.

Echinacea Hybrids

Posted on April 27, 2023 by Scott Vogt

I read an interesting article about Echinacea (coneflowers) the other day. It highlighted the highs and lows of the newfangled coneflower cultivars over the last decade or so. You know – the ones in oranges, reds, yellows and every shade in between. It seems that many coneflower breeders are doing some soul searching and they are coming full circle, back to producing hardier varieties of our wonderful native prairie wildflowers.

*Yellow coneflowers with **Rudbeckia maxima** and prairie dropseed*

The Problems

One of the biggest criticisms of these bright colored coneflower hybrids has always been their (lack of) persistence in the landscape. If you were lucky, you could get one or two years out of them before they disappeared. Maybe one survived, but often you couldn’t find that variety anymore, because it had been replaced with another new form. You would have to go back and start over again with another new coneflower.

These coneflowers had other problems too. Winter kill, color fading and short bloom times soured gardeners toward coneflowers. They were not as reliable or persistent as their parents from the prairie.

*‘Julia’ is a hybrid coneflower sporting vibrant orange flowers on strong stems. Photo courtesy of Walter’s Gardens.*

Problem solving

I can still remember offering those first forms such as Orange Meadowbrite and Razzmatazz. These diverged from the adapted forms of Magnus, Ruby Star, White Swan and Kim’s Knee High in dramatic fashion. We no longer only had pink and white coneflowers, but a warm rainbow of colors available on the market. Everyone wanted to try some in their yards.

The problems quickly became evident and the novelty wore off. The coneflower fad stalled. Breeders began to look at coneflowers from a “whole plant” approach. A “good” coneflower was no longer identified by its unique color, but by the extended bloom times, heavy flower count, longer life span, and vibrant colors that don’t fade. Winter survival and multiple growing points were a focus as well.

Most of these colorful coneflowers are produced through tissue culture production. However, some seed forms with reliable color, such as Cheyenne Spirit and the Pow Wow series have become a cost effective alternative to tissue culture forms of coneflowers. These seeded forms are consistent, vibrant, and affordable.

Going Forward

The trend for new coneflowers forms and colors shows no sign of slowing. Innovation drives sales and new styles are always on the horizon. One of my recommendations is to always start with the true natives first. Pale purple coneflower (Echinacea pallida), narrowleaf coneflower (E. angustifolia), yellow purple coneflower (E. paradoxa) and purple coneflower (E.purpruea) are adapted to our climate. They are always a good bet in the landscape. Remember, the pollinators prefer these forms too.

*American lady butterfly on Echinacea angustifolia at Chase State Fishing Lake, near Cottonwood Falls, KS (Photo Credit: Brad Guhr)*

*Our native **Echinacea pallida** always has thin, reflexed petals and a pale purple hue.*

We have been tinkering with coneflowers for a long time and that will continue. The simple prairie coneflowers that we have moved into our landscapes often don’t look the same. I believe these changes come with a price. Sure you get uncommon colors, but it is obviously not the same prairie plant. Do pollinators recognize them?

If you want to try some of these new colors, choose wisely after doing some research. One of the best new coneflowers, according to the Mt. Cuba coneflower trials, is Sensation Pink.

Prairie Spring Equinox

Posted on March 22, 2023 by Janelle Flory Schrock

Last Monday’s spring equinox marks an interesting time in our calendar. We’re nearly three months into 2023, but following the seasonal calendar, a new year is just about to begin.

The spring equinox is a time of paradox – spring is both here and not yet here. Each day, as the Earth turns in its relationship to the sun, lengthening our time of daylight in the Northern Hemisphere and warming the soil, plants, birds, insects, mammals and amphibians all respond to nature’s alarm clock. Despite cold snaps and high winds, creatures up and down the food chain begin to stir.

Crocus emerge along the path to the greenhouse.

While we may grumble of tree pollen, cold snaps and high winds, something inside of is also buoyed by the innate sense of hope in this slow turning of the seasons. One of our long-time members and neighbors recently shared a series of poems with us, entitled “Arboretum Seasons”, which she wrote in response to her daily walks around the pond during the pandemic. Here are her impressions of spring, reminding us of everything we have yet to enjoy in the coming spring months.

Arboretum Spring

The Arboretum wakens with the music, fragrance

and rainbow hues of Spring

The “Chee-chee-chee” of scarlet Cardinal

the warble of black and orange Oriole

the Robin hunting worms on the lawn

the soft cooing of Doves

and the “Konkaree” of Red-wing Blackbirds

clinging to swaying Cattails lure us.

The fragrant Lilac, the Crocus and Columbine welcome us;

also the Evening Primrose that wilts in the sun.

Delicate green Birch leaves tremble in the breeze.

Vivid pink of Crabapple and pale pink and white

Apple blossoms border the path.

Forsythia adds its gold as we circle the lake.

A cacophony of Spring Peepers hushes as we pass.

Shy Violets peep from the grass beneath towering Cypress

and the Weeping Willow kisses the lake.

guard fluffy yellow goslings

from vicious Snapping Turtles.

The perfume of Mock Orange, Daffodil and Narcissus lingers with us as we leave

Words of Encouragement in a Drought

Posted on October 12, 2022 by Scott Vogt

We have all seen wonderful pictures of lush plants and fertile prairies in magazines, on television, on social media or other websites. These plants seem to be growing effortlessly. They have beautiful blooms with scarcely a leaf out of place. That is not the reality we are living in Kansas right now. Honestly, our gardens look a little tattered and worn down from the summer they have endured. The drought has taken its toll.

*The sun sets on another growing season*.

Frankly, this time of year we might feel as tired as our garden looks. We might even question why we do it. But don’t forget that a sustainable and resilient landscape doesn’t just happen on its own. It takes a little effort, but the rewards are worth it. Consider all the benefits of a native garden:

Saves water.
Doesn’t require fertilizer or pesticides.
Adapts to our climate.
Provides erosion control.
Reduces stormwater runoff.
Restores natural habitats.
Preserves biodiversity.
Attracts pollinators.

Fortunately, the native plants have survived. There are still some blooms on goldenrods, heath asters, blue sage, New England aster and aromatic asters in spite of the ongoing drought. The grasses, though stunted, are seeding out and have attractive autumn colors. True, it can be discouraging this time of year as you compare your garden to those idyllic gardens on paper or the web, but don’t lose heart. Your habitat garden is still functioning as it should.

Fall is the time to step back and appreciate your habitat landscape for what it is. Certainly, there might be more you could add or do, but this is enough for now. A successful native garden is more than aesthetics. You understand that all of these ecological benefits are important in creating a successful garden too. When you see that your garden is inviting to a diverse group of pollinators and wildlife, you know that you are creating something worthwhile.

Dividing Perennials

Posted on January 5, 2022 by Scott Vogt

A perennial border is evolution on fast-forward, a watercolor in the rain, changing weekly as various species segue in and out of bloom – and yearly as its constituents dominate or yield, flourish or succumb, according to their natures.

John Friel from Friel World in Green Profit

Friel perfectly describes a native perennial border. Each plant grows according to its nature. Some are spreaders while some stay put or fade with competition. To keep all these plants happy and harmoniously growing together, a few plants may need to be thinned from time to time – divided so that they don’t dominate too much.

*Front entrance sign will be updated with division of plants, especially grasses and asters.*

When to Divide Your Perennials

As we move into spring, March and April is the best time to begin dividing perennials. You can divide in August and September, but excess growth and heat may hinder success. Dividing perennials can be stressful on the plants so dividing during times with cool, moist conditions will reduce shock. Another thing to keep in mind is that native grasses will not start to actively grow until soil temperatures reach at least 60 degrees. Grasses are often the last plants I divide in the spring. It’s good to wait until they are starting to show signs of life.

Which Plants to Divide

How to Divide Perennials

Dig the Clump

After you have identified the plants that need to be divided, the next step is to dig the entire clump out of the ground. If the soil is dry, it is beneficial to water the area a few days ahead to soften the soil. With well-established grasses this may be a challenge, but it is important to work at it until it is removed. Grasses are resilient and can take much abuse in this division process. I have even worked at removal with a pick axe. Remove the clump/clumps from the hole and set it aside. Brush off excess soil to reveal the growing points.

Separate the growing points/crowns and replant

Some plants are easier to pull apart than others. For instance, asters are easier to pull apart than switchgrass. Usually, I break these clumps in to 1/16^th, 1/8^th or ¼ pieces. Each clump needs to have a few leaves or healthy growing points and roots in order to grow. Then, replant the divisions as soon as possible so the roots don’t dry out. I put them back into the same hole from which they were removed. Plant at the same depth as before and water well. Cover any bare soil with mulch to help conserve moisture while your new divisions become established. Left over plants can be shared with friends or composted.

Water well

Reestablish these divisions as you would any newly planted perennial. Water daily depending on the weather for the first two weeks. Once you see new growth, reduce water frequency to every other day or every three days. You have removed much of the supporting root system so it will take at least a season to get that back. Also, I would not fertilize the new transplants, because it will encourage top growth that is not sustainable with the new root system.

Which Plants to NOT Divide

While most perennials benefit from being divided every few years, there are a few perennials with deep taproots that are better left alone. You will be more successful planting new seedlings than trying to dig these plants out of the ground. In my experience, it is easier to start with a plant than to remove these plants. Too much damage is inflicted on the taproot. Avoid dividing these varieties:

Baptisia
Butterfly weed (Asclepias)
Coneflowers (Echinacea angustifolia, Echinacea pallida, and Echinacea paradoxa)

We have divided and transplanted hundreds of plants over the years and I don’t believe I’ve ever lost one. Native perennials are resilient and recover from being transplanted in about a week. They may look rough the first year, but they will really come to life the next year. Go out in the next few weeks and identify a few plants that would benefit from a fresh start.

A Winter Garden to Look Into

Posted on December 8, 2021 by Scott Vogt

This time of year our focus changes a bit as we transition to spending more time inside. You look longingly outside at your garden, anticipating warmer weather and the arrival of spring. We are not restless yet, but for those of us who garden and love to dig into the soil, it helps if we have something to look at through the kitchen window or sitting in our living room. Here are some plants to consider adding as you “look into” your winter garden.

Form

Flowers fade into buttons, globes, plumes, spikes, daisies or umbels that can be emphasized with the play of light and motion. These expired flowers are attractive even after they are done blooming.

Coneflowers: These dark seed heads are attractive with native grasses and are favorites of overwintering birds.
Asters: Swaths of these fall blooming perennials provide structure and decent fall color.
Amsonia: Blue flowers in the spring and attractive color in the fall
Prairie Dropseed: This is one of my favorite grasses. Fine foliage, airy seedheads, and golden orange fall color that mixes well with many other shorter perennials.

Texture

This garden design element refers to the surface quality of the plant. Whether coarse or fine, textural plants combined with interesting forms are quite dramatic in the winter landscape.

Switchgrass: There are so many varieties to choose, from tall to short and from green to red leaved. You really can’t go wrong by adding some of these native grasses to your garden.
Rattlesnake master: This unusual native has attractive gray-green foliage and starry white blooms in the summer. As it transitions into the winter-the whole plant turns tawny gold.
Little bluestem: The fine stems of little bluestem add bright color to the stark winter garden.

*Fall color of Amsonia with Northwind switchgrass and Oktoberfest Maidengrass*

Fruit/seeds

This element in the garden is often overlooked or removed before the birds need them. For birds that take winter residence in your garden, the right mix of plants creates a habitat that is fun to watch.

Composite flowers like blackeyed susan, coneflower, blazing star, sunflowers, and goldenrods are vital food that birds seek out.

Crabapples: Most of ornamental trees have persistent fruit that are utilized later in the winter as other food becomes scarce.
Blackhaw Viburnum: This native produces abundant fruit that taste like miniature prunes. Birds and other wildlife love them.
Sumac: The reddish fruit atop these native shrubs are a favorite of Chickadee and Titmouse.

*Robin on a crabapple tree* *(Photo Credit: Judd Patterson,* *Birds In Focus*)

Stems

Stems are not noticed until everything is bare, but can provide something interesting and beautiful to look at in the winter.

Red/Yellow twig dogwoods: They explode with color especially with snow.
Big Bluestem: Forms with brilliant red fall color are the best with regards to standing out in the landscape.
Seven-Son Flower: Great exfoliating bark on this fall blooming small tree.

Shelter

This can be a brush pile or evergreen of some type. Each provide shelter and safety for wildlife during the cold winter months.

Taylor Juniper: This upright form of our native evergreen also has fruit that the birds need.
