I've got a 'Charles Darwin' that needs dividing, this would probably be best suited to you climate. I do have a clump of Big Lagoon, CA and seed of Little Woahink, OR and a couple locations from the NE. I have some of the natural tetraploid D. × hybrida from Butterfly Valley, CA in the care of Ivan. These caused a long running flap on the ICPS listserv if you follow that. I suspect John Brittnacher will have seed of these soon. Seems very fertile and vigorous. I can't promise you one of these though, status of the plants is unknown until I talk to Ivan. All of these except 'Charles Darwin' will need fairly cold winters for dormancy.
I can send you whatever gratis since you send stuff for the LACPS now and then.
