Great White Trillium - Trillium grandiflorum
I'm not completely certain that this is Trillium grandiflorum because these flowers were already pink even though they were barely in bloom. But, I don't know what else they could be...
White petals with a deep pink blush that sometimes comes with age. The flower arises above a whorl of three, leaf-like bracts. Great White Trillium is a spring ephemeral, whose life cycle is synchronized with the forest in which it lives.
Habitat: Forest at Garden in the Woods
