Hi Sharon and all!
In extreme heat and or wind, the plant will abort pods, flowers, leaves,
etc. because (as it seems to me in Phoenix) the wind/heat is so drying, TB
iris plants cannot replenish the moisture faster than they loose
We can rarely bloom more than three or four buds during the late season
because the flowers just "melt" or dry up and never bloom when they are in bud
stage. During mid-late to late season, we usually warm up too much for our
iris flowers. That is when the hybridizing really becomes a
challenge. You can get the best most fluffiest pollen on a freshly opened
or partially opened flower early in the morning when it is still cool, and it
still will not produce a pod.

In most cases dissection revealed a mixture of the tiny
proto-seeds and growing, viable ones. So I started dissecting the
ovaries of flowers I had not crossed, which showed no signs of swelling -- and
found only uniform proto-seeds.
That's when I started making my
sacrificial crosses. Harvesting and dissecting pods in various stages of
development taught me a lot about the maturation process and gave me a basis
for comparison. Post-mortems reveals that most of my problems occurred
in the very early stage, before the folded flower had dropped off of the
ovary. Our hot, dry winds tend to dessicate the flower and turn it into
a wind-catching flag. Simply cutting the flower off as soon as it was dry
increased my success rate enormously.
Not that this
particular bit of insight is of use elsewhere, but the process could prove
