I is good to see some attention being paid to iris cristata although I would have expected it more on the species robin than on the siberian robin. There are 17 registered cultivars of cristata and another time as many that have been named but never registered. Despite this most nurseries still only offer them as blue or white which tells you nothing. Is this white the same as that white? Who knows unless they have a cultivar name. No one would every distribute a TB as just white. All of the cultivars are named selections of the species and there has been no hybrids created that I know of. All where selections from wild populations and those that have been registered often state where they were collected. I have written to Andre Viette and he has never registered ‘Shenandoah Sky’ or ‘Summer Storm’. The strongest growing cristata in my garden has been one I call ‘Edgar Anderson’ and it is blue. It was collected in Southern Missouri by that famous botanist and planted at the Shaw
Nature Reserve, a part of Missouri Botanical Gardens where it forms huge matts in the Oak woodland. I sent a piece to Jan Sacks and Mart Schafer to compare to their most robust cristata ‘Powder Blue Giant’ that was collected in Kentucky by Sam Norris. In my area ‘Edgar Anderson is much larger, but they tell me that there, it is just an ordinary cristata for them. I suspect that various clones will have different regions in which they perform their best. Until we can get into the habit of registering species’ clones we will make little progress in identifying variations and selecting the best for our gardens.
