Janet,
Thank you so much for the information! Lesser Celandine is my plant! I did some searching on R. ficaria, and found that it is listed as invasive in 2 states on the East coast. I will think twice about planting this in my yard! It has not spread far in my parents' yard in the last 20 years, though, and the climate where I am is much more harsh.
That Wildcraft Vita blog is an interesting link. Thank you for finding that one!
I appreciate your help solving this mystery.
