These are bearded irises? I'm in a zone 4 and
have always planted bearded iris seeds directly in the nursery bed just before
the ground freezes about 1" deep. Nature takes care of the chilling and soaking
over the winter and, depending on parentage, about 1/2 come up the following
year around May. (Our soil is primarily sandy to sandy loam.)
Not all seeds will germinate the first year. Some
need at least 2 rounds of freezing and thawing to break dormancy and I've had a
few that germinated 8 years after sowing.

looking for suggestions. Should I find someone else to try to grow the seeds
or is there something else I could try?
