Patty, I think mine is Iris reticulata. I'm not sure, I'll have to look. I know it is a type of bulb and not a rhizome. I don't know very much about Iris, just that I love these tiny ones. I do have a few of the Bearded Iris that I got years ago from my mom. I do love them, but have no desire to collect them.
Can't wait to see the one I got from Greg bloom.
