I collected about 100 seeds. I've kept about a dozen and sent the rest to the species group at the British Iris Society. They are going to try to grow them as well. They were REALLY excited by it. I'd tried to find out what it was and when I couldn't find it, I sent the pictures to a garden plant specialist in England. About a week later I had the BIS mailing me with an identification and a request to write up a piece for their Journal.
I left most of the seeds on the plants so they can self seed and increase in number.
It really is a quite extraordinary colour for an Iris isn't it!
