Does anyone know what happened to this iris? It was a freebie I recieved with an order last year, but I can't find the name just now. I noticed it had bloomed, out the window, but could only see 2 falls and thought the other must have blown off in the high winds we've had. When I went out to look though, it's clear that the entire flower has only two of each part. Is this a defect that will be seen in all the blooms or just this one? Does anyone know the cause? If it doesn't hurt anything else I'll just leave it as it's a pretty one, even it's not all quite there. Sorry the picture isn't focused better, it was cold and drizzly so I hurried.
