Echinacea Hybrids

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.

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.

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.

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.

March Gardening Checklist

While March can still be cold in Kansas and we can get some significant snow and ice, there are still opportunities to spend time in your garden. Here is a March gardening checklist that will prepare your garden to thrive in the coming year.

Prune trees and shrubs

This is a perfect time to be pruning trees and shrubs. Maybe there is a branch that is always in the way while you mow, or shrubs that are encroaching on a walkway. Cut them back. Keep in mind to only prune shrubs that flower on new wood. Pruning shrubs like forsythia and lilacs will remove blooms for this spring. Spring blooming shrubs can be pruned after they are done blooming in late April or May so they have time to set new buds for next year. Check out this blog by Katie, Old Wood, New Buds: A Pruning Guide.

Cut back flower beds

Now through March is the time to trim back ornamental perennials and grass stalks to clear room for new growth. By cutting these plants back it you allow sunlight to reach the crowns and warm the soil. We have talked about it several times, but it is worth repeating – if you can help it don’t carry stalks away from your garden. Leave them as natural mulch. These stems and stalks harbor native pollinators that you want to keep in your landscape. If thatch is too thick, remove it to an obscure place in your yard or along the alley.

Apply compost to soil

If you haven’t already, empty out your compost bin and put it on your garden. Prepare your garden soil if it’s dry enough to work. Dig in compost and other amendments when your soil can be worked. Only do this if your soil is dry enough.

How do you know when it’s safe to work the soil? When a ball of soil crumbles easily after being squeezed together in your hand, it’s dry enough. With our clay soils, avoid compacting your garden soil. Wait until it’s dried out before tilling, planting, or even walking in the garden beds.

Loosen mulch

Mulch has a tendency to fuse together, especially with mulch more than a couple inches thick. This cake layer along the top resists moisture penetration and seals off the soil, restricting good air exchange. It is good each year to rough up the mulch with a fork or rake to break that seal. This will open up the soil to moisture and positive air movement. Tree and shrub mulch rings and shrub borders will benefit the most from this exercise. While you are at it, maybe a fresh layer of mulch is needed. I typically have 2-3 inches of mulch around these woody plants.

Continue to gather ideas

There is so much information available to gardeners these days. Choose plants that create habitat and attract wildlife to your yard. Review your garden journal from last year. Read horticulture magazines. Attend the lectures and presentations at your local garden shows such as the Harvey County Garden Show on March 25 and 26 here at the Arboretum.

Regardless of what season the calendar says, there is always something to do in the garden. Spring is coming, so now is the time to get ready. I don’t know about you, but I am ready to see some blooming plants again.

New Native Plants for Florakansas

“New native plants” is a misnomer we use a lot throughout our blogs and newsletters. In fact, they have been here for eons! But we get pretty excited around here when we can add a lesser-known native to our inventory for the first time. “New” just means newly available to our customers. Thanks to growing demand for natives in the landscape industry, more wholesale growers are expanding their offerings, which means we can expand our FloraKansas selection.

Solidago flexicaulis, zig zag goldenrod

A goldenrod that prefers shady, woodland conditions, Solidago flexicaulis can be found in far eastern Kansas and throughout the Ozarks, all the way to the east coast! This plant presents a great opportunity to get some color and pollinator attraction in shaded areas. Its name refers to the zig zag pattern of blooms up the stem. To identify it from other shady goldenrods like Solidago odora or Solidago caesia, look for the wide leaves with dramatically serrated edges. Companion plants include wild geraniums, columbine, and jack-in-the-pulpit.

At less than a foot tall, we don’t want you to accidentally pass this one by! Limestone calamint is found growing in the open glades and rocky prairies of Missouri and Arkansas, along with a few populations scattered in New Mexico, Texas, and the upper Midwest states. Tube-shaped flowers typical of the mint family will attract plenty of pollinators. Plant in soil that is well-drained, rocky, and slightly alkaline, in full to partial sun. Plant with similar sized friends that like rocky soil too, such as blue grama grass and perky sue.

Most roses you see in the flower shop or floral department of the grocery store are not native roses. Not even close! Shipped from all over South America, they have made us forget the simple beauty of our own native rose species. Wild roses may not have the massive, overstuffed blooms and countless layers of petals, but these natives are much easier to care for, provide tons of nectar to insects, and smell heavenly. Pasture rose is 1 to 3 feet tall and likes open, sunny exposures. As a native species, it is more resistant to rose-rosette disease than ornamental types. Very thorny, these roses can be used to form low hedges or a living fence.

These diminutive and inconspicuous native plants live their life in the prairie understory, shaded out by taller species all around them. Blooming in spring, they are great next to sidewalks and in areas you pass by frequently so you don’t miss them! Prairie violets very closely resemble the other species of violet we carry, Viola pedata (bird’s foot violet), but that one has orange stamens and prairie violet does not. Both are host to many butterfly species but they do not spread as aggressively as common violets. These look great with crocus, and spread nicely underneath grasses like little bluestem.

Spring will be here before you know it! Which native plants will you add to your garden in 2023? Check our FloraKansas page for updates about the spring event.

Words of Encouragement in a Drought

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.

The first year: Getting native plants established

Originally published on May 27, 2020

The prairie communities we see are diverse and complex.  Plants, intricately woven together, crowd out weeds and harmoniously coexist.  When you look at a prairie, you only see about 1/3 of the plant.  The root systems that sustain these native plants make up the remainder, because they reach deep into the soil.  The first year is so critical to the whole process of getting native plants established. Developing these root systems properly is vitally important and the establishment period takes time.  Here are a few steps I take to get my new native plants started. 

Prairie Photo by Brad Guhr

Planting

I like to lay out the entire area by placing the plants where they are supposed to be planted.  This does a couple things: first, it helps with proper spacing of the plants and second, it helps to visualize the final outcome.  Think about mature size, rather than what the plants looks like in its infant state. 

Now that we have the plants laid out, we can start putting them in the soil.  It is critical to not plant them too deep.  In our heavy clay soils, it is best to plant them level or slightly higher (1/8 to ¼ inch) than the soil line, especially in heavier clay soil.  This keeps the crown drier, which is important for disease control.  Over time, these natives will develop at the depth they prefer to grow in. 

Lay out entire bed for proper spacing

Watering

Now that the plants are in the ground, they need frequent watering until they get established. Even drought-tolerant plants need to be watered daily until they begin to root and connect with the soil around them. Keep in mind that improper watering is the most common reason for plant loss during the establishment period. 

For me, I water each new area by hand rather than with a sprinkler. It helps me control the amount of water each plant receives and directs it to the intended plant.  I water every day for the first two weeks depending on the weather.  After that first two weeks, you should start to see new growth. 

For the next few weeks, I water every other day or every third day as needed, monitoring the planting each day for signs of stress/wilting. 

Even after this month long process of establishment, each plant must be monitored and watered through the following summer, fall, winter and spring.  Native plants are not established until the second summer. 

Remember, it takes a few years for those roots to fully develop.  If your plants are properly sited, you will not need to water much after the first full year.  However, if you must water your area during a dry period, natives will appreciate deep and infrequent watering.

Don’t Fertilize

People ask me all the time about fertilizing native plants.  As a general rule, I don’t fertilize our native plants especially during that first year. Think about those small plants in the ground and what will happen to them if they are fertilized. They will have tremendous top growth that is not sustainable by the small root system. This will put the plant under stress and slow its progress. 

Natives are resilient and adaptive. The deep roots most often will find the nutrients and moisture each plant needs.

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.

If you decide to mulch your display beds initially, only place one to two inches of mulch down and keep it away from the stems.  This is fine as the beds are first established. As they mature, less mulch is needed because, with the right care, the plants become the mulch.  Something to think about is whether you have seen mulch in the prairie?  No, the plants eventually co-mingle and intertwine to push out weeds.     

Creating a native landscape takes time.  With each new plant established comes an expectation of a brighter future. Often, we garden and landscape our yards with the anticipation of what we will get rather than what we are giving back.  By adding native plants to our gardens, we will help make our gardens not only beautiful, but also productive and full of life.

Defining Common Horticultural Terms, Part 2

We encounter many enthusiastic new gardeners at FloraKansas who have heard about the importance of planting native plants, but don’t yet have the knowledge base needed to establish a successful planting. If you’re dreaming of a flourishing prairie pollinator garden, let me unpack the why behind the what of a few more horticultural terms for you.

Host Plants

Often, the focus for our gardens is on blooms and succession of blooms, more so than host plants.  Beautiful gardens in full bloom are what we see in catalogs, magazine and books. It is natural to gravitate toward these flourishing gardens that nectar-seeking butterflies need to sustain themselves. However, host plants (food for butterfly caterpillars) will keep them coming back to your landscape for years to come.    

It’s important to plan for the entire life cycle of a pollinator. Butterflies need places to lay their eggs.  Think of host plants as the baby nurseries of the garden. Female butterflies will flit and flutter through your garden looking for the right plant to lay their eggs. Some will lay their eggs on stems, or on the underside of leaves, hidden from predators. If you have a variety of host plants, you will attract a variety of butterflies.

Ultimately, the goal of any habitat garden is to provide everything those butterfly species need to complete their life cycle. Food for all stages of their life cycle, protection, and water are needed at different times throughout the year. The tiny larvae (caterpillars) will emerge and begin eating on the host plant. As they eat, they grow until they leave the plant and form a chrysalis. It is a fascinating process that you can watch unfold in your own garden. 

Here are a few host plants and the pollinator they attract:

  • Wild Lupine – Karner Blue butterfly
  • Golden alexander – Black Swallowtail butterfly
  • New Jersey Tea – Spring Azure butterfly
  • Columbine – Columbine Duskywing
  • Smooth Blue Aster – Crescent Butterflies
  • Little Bluestem – Leonard’s Skipper
  • Prairie Violet – Fritillary Butterflies
  • Pearly Everlasting – American Lady
  • Milkweeds – Monarchs
  • Paw Paw – Zebra Swallowtail butterfly

Sunlight Defined

Knowing how much light you have within your landscape is an important piece to a sound design. By simply watching sun patterns throughout the year, you will be able to determine how much sunlight your garden receives. Industry standards and labeling can then be used to assist in selecting the right plants for your landscape conditions. Here are some terms worth knowing since all plants require sunlight to grow, but differ in the amount and intensity of light needed to prosper. 

  • Full sun – Plants need at least 6 hours of direct sun daily
  • Part sun – Plants thrive with between 3 and 6 hours of direct sun per day
  • Part shade – Plants require between 3 and 6 hours of sun per day, but need protection from intense mid-day sun
  • Full shade – Plants require less than 3 hours of direct sun per day

Full Sun

Not surprisingly, this type of light describes what most prairie plants need. They enjoy open, bright sunny locations with direct sunlight for most of the day. This could also be morning shade/afternoon sun or vice versa, as long as there is at least 6 hours of continuous sunlight. Most of these plants have deeper root systems or adaptations that help them endure this light intensity for the growing season. 

Let experience be your guide when situating plants. Yes, some plants can handle full sun, but need protection for the hot afternoon sun. Or they can handle full sun with consistent moisture. This is the other reason to understand your site, including soil moisture, soil type, root competition and drainage.  All these factors directly affect plants too.  

Sun loving prairie plants

Part Sun and Part Shade

These light definitions are quite a bit different than plants for full sun.  Plants for part sun and part shade obviously require less light, more importantly, the light intensity is a key factor for their endurance and success.  Filtered sun for most of the day or morning sun afternoon shade fit the bill for situating plants.  Too much direct sunlight for too long a period will stunt plants needing part sun or part shade. 

There is often a fine line between getting too much sun that the plants suffer and getting too little light that the plants don’t bloom. For either group, providing direct morning sun is often the best choice.

Full Shade

Most shade plants require anything from the dappled shade found under deciduous trees, indirect light found on the north side of the house or deeper shade found under evergreens. In our area, growing shade plants can be a challenge because we are trying to grow shade plants in what was once a prairie environment with intense full sun. True shade plants often perish because they get too much sun, too much hot dry wind and/or too little moisture.

To successfully grow shade plants in our area, they need protection and consistent moisture. Any shade gardens must mimic the woodland environment. Loamy soils with leaf litter, consistent moisture – but not too much! – and protection from drying winds. It can be a challenge, but shade gardens can be carefully created with the proper light conditions, too.

The New Kansas

Compared to the average human lifespan, Kansas is old. 160 years old to be exact. But before it was a state, it was just one unbounded part of a vast Great Plains grassland landscape. It was home to millions of bison, nomadic and agrarian Indigenous people, and lots of grass. Before European settlement in this area, Kansas was dominated by grasses. Woody species had little chance of surviving the dry weather patterns and frequent fires. But times have changed. Cities, towns and homesteads come with lots of tree planting and a cessation of the much needed fires that keep the grasslands grassy. Our modern neighborhoods don’t resemble these ancient landscapes. So how can we truly plant native species if much of our garden space doesn’t have prairie conditions anymore?

Understand Your Microclimate

Microclimate is all about the conditions in a very specific area. A microclimate might include your entire yard, or just that one spot on the side of your house. Factors like windbreaks, ambient heat from foundations, or compacted soil from foot traffic mean that your garden spot is completely unique. You may have built-in irrigation, or get extra run-off from your neighbor’s roof, or have a leaky water faucet that saturates the soil around your garden. All this adds up to a very different set of conditions from the historically treeless, windy, dry prairies of early Kansas. Your ‘prairie garden’ might not be right for all true prairie plants.

This graphic is from the great guide, The Tallgrass Restoration Handbook available from Island Press. In the book it is used to show the prairie continuum as it moves from prairie to oak savannah habitats. I like to use it as an artistic illustration of time as well. Each box can represent our state at a different time period: at the top is a relatively treeless Kansas with mostly open grassland. In the middle we see early settlement and homesteading with trees planted and less fires, and at the bottom is a depiction of our state today with much more tree cover in our cities, towns, and cleared pasturelands.

Native vs Near Native

Hearing your yard isn’t compatible with plants native to your county or region is a real bummer. But perhaps your garden is just perfect for, say, Ozark native plants. In a medium-to-dry shaded yard with root competition from mature trees, the forest flowers of the Ozarks will perform much better than prairie plants, even though they are not native to your county. Considering how species have shifted to and fro over millennia, these neighboring species are still water-wise and beneficial for wildlife. Maybe your yard is sandy/rockier than expected. Try far western Kansas or Colorado species. Plants in that region love extremely fast drainage and dry conditions. Unless you are a professional conservationist intentionally restoring wild area as closely as possible to its original species population, it doesn’t pay to be too pedantic in the garden.

Packera obovata is native to eastern Kansas, but is more commonly found in the open woods of Missouri and Arkansas.   

Crank up the Chainsaw

If you want to plant prairie species, you need open space and sun. Cutting down trees can make this a reality! It sounds scary, but removing trees from your yard is okay. We have been led to believe, via international tree planting campaigns, that all trees are sacred. But that’s not the case in our area. We should absolutely preserve heavily forested ecosystems that host wildlife dependent on trees. Think: Congo Basin, Amazon, Taiga, etc. But the Great Plains grass-dominated ecosystem functions best with fewer trees.

Our wildlife thrives in a relatively tree-less environment. If you have non-native, unnecessary trees in your yard, consider removing them to create more sunny space for your prairie perennials. Down with invasive ornamental pears and Siberian elms. Yes, even some native Eastern red cedars should be ousted. Unchecked, they are a huge problem for prairies. If this seems too extreme, you can simply limb up your trees to allow more light through.

Good land stewardship sometimes means taking down trees. If those trees are invasive species, diseased, or taking up space where native prairie plants could be thriving, then down they go!

The Right Plants for the Right Place

Folks often ask why we don’t only offer Kansas natives. They also ask why we sell plants with special horticultural varieties as well as the straight native species. Because most of our customers are homeowners aiming to feed birds and provide pollinator habitat, we offer options that will perform well in the reality of residential environments. This might mean their yard isn’t right for what is truly native to a 50 mile radius. Or perhaps the space is better suited to less aggressive, taller/shorter, or seedless horticultural variety that fits their garden dimensions.

We hope to help everyone, regardless of their garden situation, to find beneficial plants that create habitat and bring joy. Offering plants to the whole plant-loving spectrum, from the newcomer planting their first wildflower to the experienced native plant purist looking for local eco-types, we are here to educate and assist.

Dividing Perennials

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.

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

  • Yarrow
  • Asters
  • Coral bells
  • Joe Pye weed
  • Liatirs
  • Monarda
  • Rudbeckia
  • Coreopsis
  • Spiderwort
  • Sneezeweed
  • Goldenrod
  • Echinacea purpurea varieties
  • Vernonia
  • Sunflowers

Native grasses often form a “donut” – the center dies back with active growth on the outer edges. 

  • Panicum
  • Little Bluestem
  • Big Bluestem
  • Indiangrass
  • Sideoats
  • Blue Grama
Grass that would benefit from being divided

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 1/16th, 1/8th 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

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.
Coneflowers with little bluestem

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.

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.

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. 
  • Alleghany Viburnum: Tall semi-evergreen shrub with attractive fruit and leathery leaves. 
  • Brush pile: Brush piles create shelter that conceals and protects wildlife from predators and weather. Situate the brush pile where you can enjoy wildlife viewing.

In the winter, there are fewer times of satisfaction from the garden. If you have only a few plants to watch in the winter landscape, make sure it’s enough to keep it interesting.

Seeded Prairie Checkup

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

Good Germination

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

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

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

Species Identified

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

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

Weed Management

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

Attracting Insects

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

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