“Thou blossom bright with autumn dew… .”—William Cullen Bryant

September on the prairie opens with a suite of delights, despite the dry weather in the Chicago region. Skies this past week veered between a celestial milky ice…

…to a startling aquamarine fleeced with clouds.
Ware Field plantings, Lisle, IL.
In my backyard mix of traditional garden and prairie, a Cooper’s hawk keeps an eye on the bird feeders. She considers the whole spread her personal salad bar. The chipmunks and hummingbirds won’t get close, but the squirrels take a more laissez-faire approach. Not a bunny in sight.
Fall wildflowers and grasses fling themselves into the new month, bent on completing their cycle of bloom and set seed; bloom and set seed; bloom and set seed.
Indian Grass (Sorghastrum nutans) and Big Bluestem (Andropogon gerardii).
The low light filters through the now-golding tree leaves, a memo from nature that time is running out for warm season pursuits. I love the seed variety in the prairies and savannas. They range from sharp…

Pale asters froth up like foamy cappuccinos.
Ware Field planting in early September.
As I hike the prairie trails, I look for some of my fall favorites. White goldenrod, which looks like an aster, is tough to find but worth the hunt. That name! Such an oxymoron.
White goldenrod (Oligoneuron album), Schulenberg Prairie, Lisle, IL.
Hyssop stands out in the savannas; a pollinator plant favorite.
But the blue gentians are an extra dollop of delight.
Downy (or Prairie) Gentian (Gentiana puberulenta), DuPage County, IL.
As I admire the deep, deep, blues, I think a William Cullen Bryant poem about fringed gentians:
“Blue-blue-as if that sky let fall
A flower from its cerulean wall.“
I don’t find fringed gentians on my walk today, but I’ve seen them in previous years. I do discover, nearby in the tallgrass, the Stiff Gentians, sometimes called “Agueweed.” They are almost ready to open.
Stiff Gentian (Gentianella quinquefolia), DuPage County, IL.
Soon they’ll bloom, and add their tiny flowers to the prairies.
Cool breezes! That sunshine. What a day to go for a hike. I want to wander through the tallgrass, spangled with gentians, under September skies. Inhale prairie dropseed fragrance. Feel the tallgrass brush my shoulders. Feel the cares of the past week roll off my shoulders.
Possibly a Hybrid Bottle Gentian (Gentiana × pallidocyanea), DuPage County, IL.
Is there a better way to begin the month? If there is, I don’t know what it would be.
Why not go see?

It’s time.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
Rising temperatures. Light winds. Rain, forecast later in the week. There’s a sense of urgency. This is the moment.
Time to burn the tallgrass prairie.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
In 2020, the Covid-19 lockdown occurred during prescribed fire season. For the first time in recent memory, the Schulenberg Prairie—like many prairies—was left unburned.
Common Milkweed (Asclepias syriaca) Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
So much was surreal about 2020; not the least was to see the prairie in its second year growth. Spring wildflowers were partially invisible under thatch and old grasses. Black walnut saplings, sumac, and gray dogwood moved in. Prairie shrubs looked, well, shrubby, without their annual fire regime. Most stunning was the prairie pasture rose, which grew taller than I’ve seen it before, with beautiful rose hips that lingered into spring.

And now, in a matter of four hours, the last two seasons of tallgrass growth have gone up in smoke.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
A red-tailed hawk hovers, waiting to pounce on any small mammals running ahead of the flames. How do they know what fire will do? I wonder. Nearby, a field sparrow sings from a wild plum tree, oblivious to the spectacle taking place. I often find hawk feathers and other bird feathers on my hikes here; now, there will be no trace. Only ashes and bird song.

A woman pulls her car to the side of the road; rolls down her window. “Do you know why they’re doing this?” she asks. It’s an excellent question. The short answer is this: Prescribed fire helps keep a prairie healthy. Without fire, we would lose our prairies.
Fire keeps brush and trees from taking over the tallgrass and turning it to woodland.
Spring burns warm the ground. The blackened soil heats up much more quickly than unburned soil. This tells the prairie plants it’s time to grow.

Old leaf litter—dead plants—vanish in the flames, freeing up space for new growth.

Fire also helps control some weedy plants that might otherwise take over the prairie and outcompete native plants. The prescribed burns help prairie stewards maintain diversity.

I watch the hardworking women and men of the fire crew check the prairie for hikers, then lay down a waterline around each area to be burned.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
The water line, back-burns, mowed pathways, and the gravel road create boundaries that help keep the fire within a contained space.

With the help of a drip torch, different portions of the prairie are set on fire.

Up in flames go the prairie dock leaves.

The last lingering seeds of carrion flower: vanished.

Today, we embrace it. Welcome it. Respect it.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
Losing our prairie burn season in 2020 was only one of many losses in a year full of assorted griefs.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
But with today’s prairie fire, I feel joy.
Schulenberg Prairie, The Morton Arboretum, Lisle, IL.
At last. There’s hope for the season ahead.
