Trillium sessile; Liliaceae
Toadshade, like so many red-brown flowering plants, is pollinated by flies and beetles. The flower is stalkless (hence “sessile”) and the three petals remain mostly closed. It’s a low-growing, clump forming plant that loves deep shade, and shows the trilateral symmetry so often seen in monocots:
It ranges from New York (where it’s endangered) and Michigan (where it’s threatened) in the north to North Carolina in the south and west as far as Oklahoma.
A somewhat rare yellow variety can be found near Carderock. Native plant enthusiasts all seem to know where the clump is and always go pay it a visit.
I love this plant beyond reason. I can’t explain it other than to say that the common name makes me laugh.
