Plant Profile: Rattlesnake Master (Eryngium yuccifolium)

Posted on May 30, 2018 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 18^th and 19^th 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.

Partner Perennials

Posted on April 5, 2017 by Katie Schmidt

As the weather warms up and perennials begin to sprout I find myself in the gardening mood! Whether filling in gaps in an existing garden bed or planting up a new area, knowing which plants will look best together can be a sort of guessing game. But a fun one! When I start getting too many ideas about what plants to pair up, I put pencil to sketch pad and doodle my ideas into reality.

There are countless unique, easy combinations for every situation that can incorporate natives, exotics and even our old garden favorites. Maybe you can use some of my recent sketches, maybe they will inspire you to draw up some of your own!

For the Shady Place

Try partnering bright colored blooms together and using leaf color that adds contrast. For example, using light greens behind darker greens can add depth and interest to an area that is only foliage. You can use striped hostas (Liberty, June Spirit, Brother Stephan) to liven up a dark area and use lowgrowing spreaders as ground cover between them (Ceratostigma plumbagnoides, Gallium odoratum) In my shade garden at home I already have some hostas planted, so I am thinking of filling in around them with some native Silene stellata (Starry Champion) and some non-native Epimedium rubrum (Barrenwort). Waldesteinia fragoides (Barren strawberry) might be the perfect ground cover to suppress weeds around it all. The purplish hue of the epimedium blooms will work well with the yellow of false strawberry since they are complementary colors (situated opposite each other on the color wheel).

If you have a shady spot, try planting fillers between hostas to add interest and texture.

Good pairings for part sun areas:

Solidago rigida (Rigid Goldenrod) + Anemone ‘Pink Kiss’ (Pink Snowdrops)
Heuchera ‘Fire Chief’ + Carex pennsylvannica (Pennsyvannia Sedge)
Asarum canadense (Wild Ginger) + Matteuchia struthiopteris (Ostrich Fern)

For the Hottest Hot Spot

What plants can partner together to beat the heat? A dry, hot spot is a perfect place for mixing native grasses and wildflowers that have evolved in the prairie sun. For a rock garden or sunny burm, try this combination of Eryngium yuccafolium (Rattlesnake Master) and Eryngium planum (‘Blue Glitter’ Globe Flower) that will complement each other’s whimsical, spherical blooms. Sporobolis heterolepis (Prairie Dropseed) and Delosperma (‘Firespinner’ Creeping Ice Plant) will fill in around the base of the taller plants. Not only are the Eryngiums major pollinator magnets, they are also long lasting cut flowers! The bright orange-red blooms of the ice plant will warm up the cool hues of the eryngiums.

A mixture of grass, upright specimen plants and crawling ground cover will create a nice balance

Other suggestions for full sun pairings:

Achillea ‘Moonshine’ (Yellow Yarrow) + Callirhoe involucrata (Poppy Mallow)
Rudbeckia missouriensis (Black Eyed Susan) + Helenium ‘Salsa’ (Sneezeweed) + Sedum ‘Lidakense’

If You Need Some Height…

Perhaps growing along a fence or forming a border between yards, tall plants provide structure for the garden. A columnar grass species like Panicum ‘Northwind’ (Switchgrass) or Miscanthus (Silvergrass) can be the eyecatching backdrop for other perennials. They also provide support to tall flowers that might otherwise flop over when they reach their mature heights. Planting Veronicastrum ‘Lavender Towers’ (Culver’s Root) or Eupatorium maculatum (Joe Pye Weed) between tall, strong stemmed grasses can keep them upright in a stiff prairie wind. The sketch below shows a shorter variety of Joe Pye called ‘Baby Joe’ situated between some Miscanthus grass with Scabiosa (or, just as well suited, Knautia) growing wispily in front.

For an area that can use some height, install some Miscanthus grass for a big effect in fall.

Tall grass that will support tall flowers:

Andropogon gerardii (Big Bluestem) + Coreopsis tripteris (Tall Coreopsis)
Calamagrostis acutiflora (Karl Foerster Grass) + Salvia azurea ‘Grandiflora’

Partnering plants is the fun part of perennial gardening – let your imagination go wild! Use the color wheel to make the most of your pairings and pay close attention to foliage shape and texture to achieve a harmonious look.

A Tale of 3 Prairies

Posted on June 22, 2016 by Katie Schmidt

In the past few weeks I have had the good fortune to visit several different prairies, each under different circumstances, all of them delightful in their own way. Here’s a tale of 3 prairies for you, in hopes you become inspired to visit these places as well!

Willa Cather Memorial Prairie

Webster Co., Nebraska

Willa Cather Memorial Prairie near Red Cloud, NE.

I had just finished up the last few pages of Cather’s well-loved novel My Antonia as we rolled into the city of Red Cloud. A friend and I made a day trip to Webster County to take in the sights and sounds of Cather’s world, including this prairie just west of town which may have been the inspiration for some of her famous descriptions of plains life. If you are a lover of the prairie, you need to put Willa Cather’s work on your reading list immediately, then scurry up to Nebraska and tour her hometown, Red Cloud, (renamed “Black Hawk” in My Antonia) which is also the home of the Willa Cather Foundation. There you can have a personalized tour of her childhood home, church, and neighborhood along with the opera house and historic bank building, all still in turn of the century style. While hiking in her short, windy memorial prairie I saw lots of familiar species – silver sage (Artemisia ludoviciana), purple poppy mallow (Callirhoe involucrata) and little bluestem (Schizachrium scoparium).

Tall Grass Prairie

Chase Co., Kansas

View west from our seats. Who would want to watch the musicians when you can gaze at this?

We were far from the stage but we could hear them perfectly!

I wasn’t planning on going to the Symphony in the Flint Hills, but through the kindness of an acquaintance two tickets fell into my lap, free of charge. So with lawn chairs in tow my date and I headed out to a pasture near Clements, KS in Chase county. There was delicious BBQ to be had and an art gallery and information tent to peruse before and after the concert. The music was provided by the Kansas City Symphony; gorgeous selections were wonderfully preformed, including American folk tunes and well known tracks from Dances With Wolves and Indiana Jones. Top it all off with a live cattle drive on the hill behind the stage and the music bouncing off the hills around you, it was the perfect afternoon. The weather even cooperated – I never broke a sweat! The prairie was looking lush from recent rains; I couldn’t help but geek out on the species I recognized on the 3/4 mile walk back to the car – blue false indigo (Baptisia australis) and spider milkweed (Asclepias viridis). Save up some cash and treat yourself to this art-filled prairie experience next year!

Maxwell Wildlife Refuge

McPherson Co., Kansas

During the EPS week here at the Arboretum, I had the privilege of chauffeuring some of the participants on their field trip to Maxwell Wildlife Preserve. A good day at work, to be sure! It’s a beautiful expanse of preserved prairie that is home to Elk and Bison.

View near the Maxwell observation tower.

The walled trailer we were riding on let us get extremely close to the bison without the danger. Incredible viewing!

There were too many calves to count, perfect timing for our group.

Calf and mother stick close together.

The tour guides were charismatic and knowledgeable, providing a history of the refuge and a natural history of the land. The prairie there is healthy and diverse, giving us a look at butterfly milkweed (Asclepias tuberosa), lead plant (Amorpha canacens), goats rue (Tepherosia virginiana) and rattlesnake master (Eryngium yuccifolium).

Each prairie region has its own unique charms, from thick tall grass areas in the east to short and scrubby land in the west – Carve out some time this summer to visit and compare!
