These strange and beautifully horrible plants (Caulophyllum thalictroides) pop out of the ground in early spring and begin blooming right away, well before the plant is out of the Bela Lugosi stage. Later, like any good vampire, they will adapt themselves to woodland society, and appear to be ordinary green-leaved citizens of the forest. But you have seen them as they really are.

Flora Pittsburghensis is slowly expanding again, with more pictures of the flowers of spring.
