Uvularia sessilifolia (Bellwort, Straw Lily, Merrybells, Sessile-leaf Bellwort)
This is the diminutive cousin of giant Merrybells above. It is so beautiful and perfect that it's hard to believe it's real. I found our woods full of them one Mother's Day and return to that spot each year around that time to be sure they're intact. No woodland is complete without this native wildflower, if you ask me, and this one is every bit as beautiful as the larger one. This little native grows from 10 to 15 inches tall, with alternate, stalkless leaves. The delicate, straw-colored bells, sometimes in twos, are drooping. These beauties colonize and form a groundcover in time. Uvulairia sessilifolia is native to the lower 48 states and Canada, so just about any zone is right.
