I have had Howdy Do for many many years. I remember someone in the iris society giving me a piece of it at a meeting. The person who gave it to me said that someone had "won" a rhizome and there was an increase on the rhizome, and that person had broken off the increase and given it to them, believing that the increase was undesireable or something. It was by Monty Byers and one of his best that I grow. I will always have it here. I like it much better than Thornbird, which won the Dykes medal.
