I have some reputed to be rebloomers, but refuse to baby them with separate beds and extra water. I am in 7a, close to the border with 6b. Of the several I have, only one has actually rebloomed and I culled it because I didn't like the form, nor the intense shade of yellow. I prefer very light yellows or very light oranges. They light up the garden without clashing.
It was odd seeing a rebloomer all by its lonesome on days when it was so cold that I had no desire to be out in the garden. All the rest of the garden was dormant. I'd prefer that irises all save their strength for putting on an amazing show in May, when I can enjoy being out there with them.
Most rebloomers do not have the type of form that I like. Perhaps when hybridizers have worked longer on improving their form, I might like them better, but I think I'll be long gone by then.
