I submitted this as Cardamine trifolia, which was questioned by another member. I see it looks quite different that the only other photo in our database. My ID was likely from a nursery tag, which can be erroneous (frustrating but true). This was sacrificed in a water feature re-do, so I can't post any other photos. This was taken in the fall and it had little white flowers in the spring. That's all I really remember about it. If I can get a positive ID, I'll move it to the proper database entry. Otherwise I'll just have it deleted, it's not in my world anymore.
