Have had this awhile but don't know it's name. I see several that are similar but I can't really tell. Thought I'd try to see what came up in the iris forum. It's about ten inches tall with the bloom.
I added the second photo of todays bloom and it is much less yellow than the first.
Here is a third photo day three. If you compare it to the photo by Brock Heilman in the AIS iris encyclopedia........
