Also...

The seed pods should be carefully cut open and the seeds planted about 3/4 inch deep in pots of garden soil or potting mix. If the pots are kept moist, the seeds should begin to germinate with the first cool nights in October or November. The seedlings can be planted into the garden in early spring. Most can be expected to bloom the following spring.

Good luck they are beautiful. Get them growing and trade some seeds with me in the futre.

I have not grown this variety, but I have noticed iris seeds that have been planted or fallen from my summer blooms are starting to sprout. I have been seeing iris sprouts all over the place. The October sprouting time probably applies to other varieties also
