Dennis Kramb wrote about Iris cretensis and Gynandriris sisyrinchium. I. cretensis is a member of the same section as I. unguicularis and I. lazica, and presumably those are the only other species with which it could be hybridized, if one wanted to do such things. Gynandriris sisyrinchium is easy to grow from seed, which is usually available from the NARGS and AGS exchanges. It also increases well vegetatively in my bulb frame, but I haven't tried it outdoors yet. I saw it at high enough elevations that I think it could be grown along the Pacific Coast, but the Midwest is another matter entirely. (On the other hand, I can't grow Manfreda!)
