Hi, I'm an obsessive Iridophile and am slowly building a collection of species from around the Northern Hemisphere. I'm concentrating on PC species just now and have innominata, bracteata, prismatica, chrysophylla, douglasiana and missouriensis plants germinated from seed (they're really quite easy with a soak and don't really need a cold spell). I reckon I need hartwegii, fernaldii, tenuis, tenuissima and tenax. Any idea where I can get seed of these and whether I've missed any?
I'd really appreciate your help!
