Dr. Sutton was kind enough to send us not only the three species they're studying to try out on the Berry Prairie as part of the study, but also a fourth that he recommended would do well - and four of each species. We're curious folk over here, so thought we'd give it a whirl.
So here's what we received and planted:
Blue Grama (Bouteloua gracilis 'Conard')
This common short-grass prairie species was already planted on the green roof, but this particular variety ('Conard') is new to us. Blue grama is a staple in Wyoming, and on the Berry Prairie too - we have over 900 individual plants of this species planted! Let's see how this variety does.
Hairy Grama (Bouteloua hirsuta)
This cousin to Blue grama is found in the very eastern edge of Wyoming (see the Rocky Mountain Herbarium site). Although it's not found within 30 miles of Laramie, as all of our other plants, it is an interesting grass. See how the anthers dangle below the flower of the grass? That's what makes it "hairy."

Sun Sedge (Carex inops heliophila)
This sedge is found through the eastern third(ish) of the state - see the map here. It's an early season sedge so is often one of the first plants to green up in the spring (Forest Service website).
Sand Dropseed (Sporobolus cryotandrus)
This grass is a warm weather (late summer) bloomer that prefers dry, usually sandy areas. It's found throughout North America. [Prairie dropseed is my personal favorite of the Wyoming grasses, but perhaps this one will win my heart.]

Stay tuned for their progress.
