Natalie, I have never been able to notice any scent on any iris ever. So if some iris are supposed to be scented I don't know about it. And I would ignore it on a decription because I can't smell them anyway.
Mona, I moved all those iris last August into that bed. Yes, they are too crowded but the old iris bed needed to become a veggie garden. So they will stay as they are. Not touching them those year. By next year the tags should have faded into can't read them so I will have a jungle of NO IDS planted too close. I don't care as long as they look pretty.
