Pacific Coast Iris
Harden's Plum
This was the first Pacific Coast Iris that flowered for me from seed that I had sown, and it has proved to be one of the best. Seed was from a Iris society exchange, so I have no idea of the parentage, though I suspect it has some douglasiana in it. 
A shorter variety, but very floriferous, robust constitution, forked flower stems (douglasiana?) 
I may register this one.
