We went hiking in a moist woods in upstate SC recently, and saw lots of these. I can identify many plants from my childhood in CT, but I don't recognize these.
Trillium cuneatum would be my guess.
Thanks- I think that's it! I did some research, and they don't grow as far north as CT- that's why it was new to me. The woods in SC were full of them as far as the eye could see- beautiful!
Oh, one of my favorites! Congrats! My shade bed is going in in a couple weeks, and trilliums are among the first to get planted there.
