Short and Sweet: Short Plants for the Prairie Garden

Prairie gardens can sometimes be seen as messy. I have heard it many times while discussing garden plans with Arboretum members. They don’t want it to look too wild. This is a very natural tendency; humans like order, we like patterns, we don’t like chaos. But it is evident by the decline of bird, amphibian, and pollinator species that our desire for the tamed, picture-perfect lawn is ecologically unreasonable.

“What is good in terms of ecological function is often disorderly, and what is neat and tidy is often not sustainable.”

Planting in a Post Wild World, 2015

Joan Nassauer of the University of Michigan does some excellent writing, thinking and teaching on the idea that humans will respond better to ecologically friendly landscapes if they look intentional, framed, and well managed. I think the first and easiest way to achieve this for beginner prairie gardeners is to carefully manage plant height. Choosing short plants preserves sight lines, scales down the planting, and helps the viewers of your landscape more feel comfortable, less hemmed in by foliage. Here are some of our favorites!

Petite Garden Performers

Hymenoxys scaposa (prairie sunshine)

Perky Sue (Hymenoxys scaposa) has semi-succulent foliage and cheerful flowers that bloom all season long.

Hymenoxys has become a new favorite landscape plant for me. Perfect near sidewalks and in tight spots. It is a tiny little powerhouse of bloom if you keep it in full sun. Beware of planting it in a wet spot; soggy soil shortens its lifespan.

This plant makes a short, rounded clump of purple-blue flowers. It thrives in dry, poor soil and isn’t as aggressive as other mint family plants. As a bonus, it also has some interesting medicinal benefits.

Amsonia ‘Blue Ice’

Most Amsonia spp. can get quite large, but the ‘Blue Ice’ variety delivers nice foliage and blue spring bloom in a tighter package.

Amsonia ‘Blue Ice’ offers all the great qualities of Amsonia – colorful fall foliage, blue spring blooms – but stays under 18 inches. Wonderful as a filler plant for any gaps in the garden.

Missouri evening primrose is an underused landscape plant. Less than a foot tall, this spring stunner is great around sidewalks or trailing ever-so-slightly off rock edging. The blooms are large and eye catching early in the season.

Sporobolus heterolepis (prairie dropseed)

Last but not least, prairie dropseed is a short prairie grass that can be used to blend different colors and species together. Because grass acts as a unifying element it helps to lead the eye from one area to another.

All these plants will be available at our spring FloraKansas Native Plant Festival. Staff members will be there to help you choose the best plants for your space. We can make recommendations for a beautiful, ecologically friendly landscape.

Front Yard Native Landscaping

As a new homeowner, there are a thousand projects around the house vying for my attention. But none call to me more than landscaping. After a few weeks working on the basement, I needed a break! I redirected my energy and landscaped my front yard!

Walk the Walk

I talk often and openly about the ecological problems inherent with a “well kept lawn”. Now that I finally have my own lawn, I wanted to convert part of it to something earth conscious, yet attractive. With smart design, landscaping can feed birds and insects, build soil integrity, and take very few inputs. I will always have a good sized patch of weedy Fescue for the dog to play Frisbee in, but more and more of the yard will get planted to natives every year.

Proper Prep

First, I sprayed two adjacent sections of our front yard with a strong application of glyphosate. It was not an easy decision: I am not a fan of using this chemical, or any chemicals in the landscape. But when contending with bermuda grass, my options were limited. Bermuda is a fierce, non-native competitor that will easily overtake a native flower bed if not eradicated properly. On the sides of the house, where bluegrass, Fescue, and dandelions are prevalent, I expect solarization to work wonderfully next spring and summer.

Hymenoxys scaposa (perky Sue) is adorably small; six inches tall with cheery yellow flowers the size of a quarter. It is a great addition in my front yard because of its petite, tidy habit.

Planting

A few weeks later I planted right into the dead thatch of the grass. I like to plant thick, aiming for a very full, lush look and less weeding in the long term. Then I back-filled each hole with some rocky, sandy soil from a long abandoned planter box on the side of the house. This might help the clay soil drain better for the drought hardy species I wanted to incorporate. A flag at each plant ensures I don’t miss any while watering.

Though I am always so excited to plant, it doesn’t look like much for the first year. But by next fall it will be the talk of the neighborhood.

In my design, I focused on purples, whites and yellows to complement a pale blue porch. Made up of many western Kansas species, this garden is extremely drought tolerant once established, staying full of blooms for pollinators even in hard times. When I get a free weekend, I will layer the empty spaces with newspaper and wood chips to discourage weeds. Luckily, my city has a free wood chip pile nearby!

Here are some of my favorites included in the design. Many are native, others are non-natives well adapted to heat and drought:

Allium spp.
Amsonia hubrichtii
Asclepias verticillata
Baptisia minor
Ericameria nauseosa
Hymenoxys scaposa

Lavandula ‘Hidcote’
Muhlenbergia capillaris
Nassella tenuissima
Prunus besseyi
‘Pawnee Buttes’
Sporobolus heterolepis
Scutellaria resinosa

I plant Amsonia mainly for its foliage, but the blue blooms are a welcome sight in spring.

Grass But Not Lawn

I used Sporobolus heterolepis along the sidewalk and Muhlenbergia capillaris for a slightly taller focal point. To keep my front yard looking intentional, tidy, and appropriate to my neighborhood setting, I kept the plants under twenty four inches mature height, except for a few accents. My neighbors are already giving me funny looks about all the flags in my yard!

Yet to be included in the planting, Pycnanthemum tenuifolium is a must have for pollinators and for its delicious minty scent.

My co-workers have all taken their work home with them too; planting natives in their home landscapes and seeing the wonderful change in biodiversity these plants bring . It was time for me to do the same! Once the garden matures, I hope it inspires others to convert more of their underused front yard space to valuable, attractive wildlife habitat.
