Thanks Donna, it has a fun story too!! I joined ATP last November and since then have just been oohing and aahing at people's yards and plants (mostly on here via photos) well I walked by this woman's house and saw several of these popping up and said "oohh! what are these, they're so wonderful looking?" and "Have they been here long because I've never noticed them before and I walk by this house at least 2 times per week!" Anyway we began talking and she doesn't know the name, had just gotten them from a friend and had an extra gallon container of at least one, but probably several! How fun is that!! I am going to give her some Iris rhizomes in another week or so.
BTW I love your cute Avatar! Is/was that in your yard?? Its really cute!
