I wonder if one of you learned Iris people will be able to confirm this is in fact Iris gracilipes, bought by me from a plant stall rather than a nursery, and also tell me if it is unusual for the upper foliage to become like a fall as this one has done. The other flowers on the stem were normal, this was the final flower to open and I thought it had four falls til Sue pointed out it was a standard that had become coloured like a fall.
