My attempts to grow PCI have failed here in SW Ohio, but I begged pollen from Garry and Ryan (Grisso) in 2010. I tried pollinating Siberians but didn't get any takes. I just discovered I still had a lot of the pollen & so this year I have put it on everything -- versicolor, virginica, foetidissima, prismatica, Siberian, tridentata, fulva, brevicaulis, .... in the hopes of getting some hybrid seeds. Pods are actually forming, but there's no guarantee they contain any viable seeds. I'll let you know in 3 years when I start getting blooms from this year's harvest! ;-) Irritatingly, another western iris I've tried & failed with more than a dozen times now is Iris missouriensis. I don't know why it won't grow for me in Ohio. Maybe critters are eating them in winter?
