So I am in Zone 8 and though I have a long growing season, the June heat sends most my Irises into partial and sometimes full dormancy, so because of that I don't really think it is very long. I have had multiple reblooms in one year on Clarence, Autumn Circus and Lichen. Lichen has bloomed for me in the dead of winter. It even has had a December seedpod that had to have crossed with itself because there was no other Iris in bloom(lol). Sadly the seed pod froze and did not produce mature seeds. I am starting to try to cross Lichen because of that rebloom quality. Also Desert Legacy has rebloomed for me.
