Pacific Coast Irises in the east

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?
