yes, I have  quite a lot of experiance....
I do not treat the hybrids very well because they are low priority compared
to the species. They essential thing in growing these Iris in uncontrolled
rain is how they are planted. It is the same  old story of mulching them
with a lot of gravel, free draining soil and good air flow. the gravel
keeps the moisture density around the rhizomes which seems to be essential
for rooting, and insulates against heat which causes rot if the plants are
damp.
