I have always liked Iris gracilipes as a choice woodland or shady rock garden plant. However, for me it seems to be a short lived perennial, lasting only a few years before it disappears. Does anyone have any cultural tips to make it last longer? Also, has anyone germinated it from seed? If you follow Norm Deno's advice from his book on seed germination,most iris require a 2yr cycle for gerination-wet-cold then dry-hot, then wet cold and finally dry hot but I have had Iris milesii germinate in one season. Any help will be greatly appreciated         Len Lehman
