“Cherish your science but understand it as a finite guide to the immensities of time and space…Look far. Dance with the world rather than try to explain it away. Consider the boat, not just the planks. Seize knowledge. Ask hard questions. But know, too, that your intellect is a small window and that its views can be surprisingly incomplete. Feel deeply.” — William J. Broad.
What a week it is shaping up to be on the tallgrass prairie! Rain and cool weather are bringing out the blooms. Small white lady’s slippers are in their full splendor. Like tiny white boats floating in a sea of grass.
The first bright pops of hoary puccoon show up along the trail.
Nearby, another pop of orange. An immature female eastern forktail damselfly. So common—and yet so welcome right now. Emergence of dragonflies and damselflies has been slow this spring, due to the cool, wet weather.
Cream wild indigo doesn’t mind the cool conditions. It jumps right into its opening act.
The wild hyacinths add their delicate scent and good looks in washes of lavender across the prairie.
So many beautiful prairie wildflowers blooming this week, you hardly know which way to look. And oh, the juxtapositions! This blue-eyed grass is swirled into an embrace by wood betony.
While nearby, a butterfly conducts surveillance runs across the low grasses and forbs.
But the literal star of the prairie stage this week is Dodecatheon meadia. The shooting star.
Its pink clouds of flowers are so unusual. Look at that bloom shape!
Now, think “tomato blossom.” Or the blooms of eggplants and potatoes. Similar, no?
Shooting star is a tease. She beckons bumblebees with her good looks. They zip by, then pause, perhaps shocked by all that floral abundance. Buzz in for a closer look.
What the bumblebees don’t know right away is this: Shooting star has no nectar reward. The only “fault” in this star to speak of! Nonetheless, you can see this bumblebee in the photo below stick out its tongue. Looking for nectar? Grooming itself? Or perhaps letting me know it is time to quit taking photos?
As the bumblebee clings to the underside of the bloom, it vibrates its strong wing muscles. They emit a high-pitched buzz. This causes the pollen to be shaken out of the anthers onto the underside of the bee. The process is known as “buzz pollination” or “sonication.” Honeybees can’t do it. Their muscles aren’t strong enough. Which emphasizes the need for native bee conservation, doesn’t it?
Can you see the pollen in the photo below? Like yellow dust.
As the bumblebee moves on, it carries some of the pollen with it, cross-pollinating other shooting star flowers as it visits each one. Bumblebees also eat pollen, and feed to their bumblebee young. Click on this great video for more info that’s been helpful to me in understanding the process.
Watch the shooting stars. Listen to what they have to tell us. They are another reason to care about the natural world and all its creatures.
“Dance with the world rather than try and explain it.”
Make a wish.

Cindy, thanks for the lesson of this tiny flower that I saw for the 1st time at Nacusha Grasslands two weeks ago. There I got a copy of your Tallgrass Prairie Introduction book, where you’ve wonderfully put together the pieces I’ve come to understand about prairie (and more). It’s taken many visits to Nachusa, patient question-answerers, and a variety of hands-on tasks and I can’t wait to get back there! Your Tallgrass Tuesdays is a gem that keeps prairie in my mind’s eye, even when I’m not standing in it.

What a kind note, Sandy! Thank you for reading, and for taking time to let me know you are reading “The Tallgrass Prairie: An Introduction” — I’m so grateful. Happy you are finding joy in the prairie. It’s an amazing place! Grateful to hear your experiences with Nachusa.
Thanks for your post about a species of vascular plant very dear to me. I studied the life history and spring fire response of Dodecatheon meadia (now known as Primula meadia) for a master’s degree at Iowa State University. My favorite study site was Hayden Prairie State Preserve (240 acres of native former hay prairie) in Howard County in northeast Iowa. This tallgrass prairie has acres and acres with millions of blooming shooting stars generally by Memorial Day.
The James Woodworth Prairie Preserve in Glenview, Illinois (I grew up in Glenview) has a nice population of shooting stars. I assume you have been to Chiwaukee Prairie near Kenosha, Wisconsin which also has acres and acres with millions of shooting stars generally by Memorial Day.
