I grew this iris in Austin, TX (zone 8 b) for about 15 years. It multiplied vigorously and rebloomed every year. It usually first bloomed throughout April and May and then started reblooming again in late October and November. I only brought one plant with me to Houston because I don't know how well it will tolerate the higher humidity and rainfall. I will post a report about that, in the future.
