Pacific Coast Irises in the east
Dennis Kramb (Wed, 01 Jun 2016 11:49:16 PDT)
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?

Ernie’s comment, I am of the opinion that if enough people in the east
try and grow PCIs from seed nature will select those that are best adapted
for our conditions, is correct.
We have some west coast growers looking for east coast gardeners to work
with to improve hardiness in PCI. In our next issue of Pacific Iris, there
will be a request for this from Garry Knipe, a hybridizer in Cupertino, CA,
who is looking for eastern partners.
PCI also intensely dislike hot, humid summer conditions, which gardeners
may read as die quickly under these circumstances. This keeps them from
being grown in much of the south to east portions of north america.
