October Serenade

“Mornings were cooler and crisper than before. The ever-lengthening shapes of afternoon shadows seemed drawn more irresistibly into the night. Fields were rough and tweedy, as though an old brown woolen jacket had been thrown over them to ward off the chill.” — Vincent G. Dethier

Oh, wow, October. The prairie is stunning. Although it’s not to everyone’s taste.

Cup plants (Silphium perfoliatum) and sumac (Rhus glabra), Schulenberg Prairie, Lisle, IL.

“No flowers,” say some of my friends. Yes, the blooming flowers now are few. Goldenrods. Asters.

Sky blue aster (Symphyotrichum oolentangiense), Schulenberg Prairie, Lisle, IL.

They melt into the grasses, slowly becoming invisible. Going. Going. Gone—to seed.

Mixed wildflowers and grasses, Schulenberg Prairie, Lisle, IL.

Most prairie wildflowers have closed shop for the season.

Prairie dock (Silphium terabinthinaceum), Schulenberg Prairie, Lisle, IL.

Finished. Finale.

Compass plant (Silphium laciniatum), Schulenberg Prairie, Lisle, IL.

They surrender to the inevitable with elegance.

Late figwort (Scrophularia marilandica), Schulenberg Prairie, Lisle, IL.

Ravenous insects glean whatever is left for the taking.

Common milkweed (Asclepias syriaca) with milkweed bugs (Oncopeltus fasciatus), Great Western Prairie, Elmhurst, IL.

So many insects.

Rattlesnake master (Eryngium yuccifolium) with unknown insect (possibly the four-humped stink bug Brochymena quadripustulata), Schulenberg Prairie, Lisle, IL.

They make themselves at home in the prairie wildflower remains.

Days shorten.

Autumn trickles through my fingers.

Each day seems over before I’ve fully woken up. I remind myself, “Pay attention!” But—the prairie is beginning to blur. I rub my eyes and try to focus. So many seeds. So much grass.

Big bluestem (Andropogon gerardii), Schulenberg Prairie, Lisle, IL.

It’s all about the grass.

Prairie cordgrass (Spartina pectinata), Schulenberg Prairie, Lisle, IL.

Loops and whoops and swoops of grass.

Big bluestem (Andropogon gerardii), Schulenberg Prairie, Lisle, IL.

Even my old enemy, the invasive reed canary grass on the prairie, shimmers in the morning dew.

Reed canary grass (Phalaris arundinacea), Schulenberg Prairie, Lisle, IL.

In her eloquent essay in The Tallgrass Prairie Reader, Louise Erdrich writes: “Tallgrass in motion is a world of legato.”

The wind sighs as it sifts the grasses. The coda is near.

What new wonders will unfold?

Natural hybrid between the compass plant (Silphium laciniatum) and prairie dock (Silphium terabinthinaceum)–sometimes referred to as Silphium pinnatifidum, Schulenberg Prairie, Lisle, IL.

I only know this: The wonders will be more nuanced. Less easily available as immediate eye candy than when in the growing season. But no less remarkable.

White wild indigo (Baptisia alba macrophylla), Schulenberg Prairie, Lisle, IL.

We’ll have to pause. Think. Absorb. Take time to look. To really look.

Switchgrass (Panicum virgatum), Schulenberg Prairie, Lisle, IL.

Why not go for a hike and see? Now. Before the snow flies?

Schulenberg Prairie, Lisle, IL.

The prairie is waiting.

Vincent G. Dethier (1915-1993) was an entomologist and physiologist, and the author of Crickets and Katydids, Concerts and Solos from which the opening blog post quote was taken. This is a delightful book and accessible to anyone who loves natural history, or who has found joy in the grasshoppers, crickets and katydids of the tallgrass prairie. It takes a little extra work to find the book at your library. Well worth the effort.

Prairie by the Numbers

“It was, at last, the time of the flowers.” — Paul Gruchow

****

Oh, what a difference a little rain makes!

Spring has arrived in the Chicago region—at last, at last! The savannas and prairies are awash in color and motion. Warblers and butterflies everywhere you look…

…garter snakes sashaying out in the bright light to sun themselves…

…and of course the wildflowers, in all their amazing complexity.

My Tuesday morning prairie team is busy updating our plant inventory, a daunting task that has run into its second season. This spring, we are looking for a hundred or so plants out of the 500 from the inventory that we couldn’t find in 2017. The last complete prairie inventory was wrapped up in 2005, so we need a check-in on what’s still here, and what has disappeared or moved into the prairie. Knowing the plants we have will help us make better decisions on how to care for the site.

This is a high-quality planted 100-acre prairie, wetland, and savanna, which is almost in its sixth decade. Some call it the fourth oldest planted prairie in North America! So we feel the heavy weight of responsibility to get our numbers right.

Its a prairie with some beautiful blooms—and some quirky ones as well. This week, our “oohs” and “ahhs” are for common valerian (Valeriana edulis var. ciliata), a high-quality—and despite its name—uncommon prairie plant. Flora of the Chicago Region gives it the highest possible plant score — a perfect “C” value of “10.”

We’ve been hot on the trail of three more common but elusive plants that we’d missed in the spring of 2017: skunk cabbage, marsh marigold, and rue anemone.  Some adventurous members of the team discovered the skunk cabbage in April, poking through the muck in a deep gully. Now, two weeks later, it is much easier to see.

The marsh marigold listed on our 2005 inventory, a beautiful spring native wildflower…

…turned out to be a single plant, hiding among some fig buttercup (Ficaria verna) a pernicious, non-native invasive wetland species. We’ll remove the fig buttercup so it doesn’t spread across the waterway.

The missing rue anemone went from invisible to visible last week after storms moved through the area and greened up the savanna. Such a delicate wildflower!  Easy to miss unless you find a large colony.

Looking for specific plants as we’re doing now results in some serendipity. Our plant inventory team found harbinger of spring for the first time in our site’s history while looking for the marsh marigold. A new species for our site —and so tiny! Who knows how long we’ve overlooked it here.

In addition to the inventory, most of us are weeding garlic mustard, a persistent invasive plant that infests disturbed areas around the prairie. One of the perks of weeding is we make other discoveries, such as wild ginger blooms. You might flip hundreds of wild ginger plant leaves over before you find the first flower. Pretty good occupation for a warm and windy afternoon, isn’t it?

The rains also prompted large-flowered trillium to open. These won’t last long.

Look closely below behind the trillium and you’ll see the white trout lily gone to seed. All around, blooms are throwing themselves into bud, bloom, and seed production. Sometimes, seemingly overnight.

Updating a plant inventory plus a little judicious garlic mustard weeding will teach you how little you know about what is happening in your little corner of the plant world. I see plants that look familiar, but their name eludes me. It takes numerous trips through my favorite plant ID guides to get reacquainted. I also look in vain for old favorites which seem to have disappeared. (Where, oh where, is our birdfoot violet?)

Spring keeps you on your toes. It reminds you to be amazed. It constantly astonishes you with its sleight of hand; prolifically giving new species and flagrantly taking them away. And as always, there are a few surprises.

Ah. The “elusive, rare” red tulip! Where did that come from? Huh.

Just when you think you know a flower, it turns up a a little different color, or gives you a new perspective on its life cycle. To see the wood betony at this stage always throws those new to the prairie for a loop. Almost ferny, isn’t it?

Barely a hint now of what it will be when it grows up. Same for the prairie dock, tiny fuzzy leaves lifting above the ashes of the burn.

Or the hepatica, most of its petal-like sepals gone, but the green bracts now visible. Looks like a different plant than when it was in full bloom.

Pasque flower is now past bloom. As stewards, we turn our thoughts toward the first seed collection of the season and propagation for the next year. If a species is gone, or seems to be dwindling, we’ll consider replanting to maintain the diversity of the prairie.

We tally up the numbers, check off plant species. Update scientific names which have changed. But no matter how the spreadsheets read, we know one thing for certain.

What a glorious time of year it is! Spring on the prairie is worth the wait.
