Hello, Here in southern Europe D irioides is common and easy to get. It naturalises in certain positions. Half or full shade it make a lot of seed. D. grandflora a much bigger and more attractive plant, is much harder to find and needs milder conditions. D. bicolor once established, makes (in full sun) impressive borders or haies and becomes un interesting garden feature.

The true D. iridoides is hard to come by. David E. Central Coastal California _______________________________________________
