Dear Jim, As an expert on Iris I would think you would know more than most of us. What are the defining differences between Iris japonica and I. wattii? I was given a plant by a friend that looks like Doug's and the friend didn't know what it was. It has been quite happy growing in the ground in my garden with little care and is in bloom right now.
