It can become an obsession to ID a plant. I have around 150 Hosta and have had only one I couldn't ID. I was about to put it on here this morning when something came from the the recesses of my mind that it is Inniswood. As I think about it now I remember moving it from another spot in the garden. Then it was planted poorly and floundered for a couple of years. Finally I replanted it and now it is growing. I grow Inniswood in another part of the garden and compared leaves. Bingo!!!!! It is Inniswood which I love..
