UNKNOWN PLANT

It's Toadshade Trillium (Trillium sessile), or maybe Sweet Betsy (Trillium cuneatum)........or maybe some other Trillium, but definately a Trillium, which is a native woodland wildflower here in the USA

I forgot to mention that it's healthy, but something has been eating on it like a slug maybe.

You will have a fit when I tell you that Trilliums like this were selling for nearly£15 for one little plant at the Nursery I visited today! (no, I didn't buy one)

Thanks for the information.
Spritzhenry ~ I've only seen the one trillium in my yard and sure am enjoying it. It's even more fun knowing they are rare
