Hello all, I know I won't be gardening with this plant, but I just can't identify what it is.
I am in Maine at the moment, and this was found along the Stillwater River near Orono. The location was practically full shade in a Northern White Cedar stand, along with troutlilly plants. The area was almost along the riverbank so the soil I would imagine is constantly wet, but not marshy wet.
I found a plant about to lose its petals and counted them. 8 petals altogether though now that I'm looking at the photo I see a petal on the ground.. so its either 8 or 9 petals.
