Here in SE WIsconsin, zone 5, I find they flourish in our hard clay
soil. It's almost as if they LIKE the hardpacked earth, with their
rhizome tops exposed. I once began a new garden, amended the soil very
well, and planted 15 new irises. NONE of them made it over winter (and
it was a MILD winter). My theory was that the nice organic matter in
the soil caused them to shift too much. Just a theory, but I've never
planted them in anything but hard clay since, and they grow like mad for
me! I do fertilize regularly before bloom - to make up for the
nutrients the clay lacks.
