I have inherited some beardless irises in a community garden. Is there a way to distinguish between the 3 types from the leaves or growth habit? The plants bloom a few weeks after bearded irises. The blooms are 4-5" in diameter and did not hold up well as cut flowers. Unfortunately I do not have a photo of the blooms but they seem similar (to an neophyte's eye) to photos of all 3 types I found on the web.
