Aunt Margaret TB Tries every year, but usually "freezes out" in 5a
Autumn Orange SDB very reliable rebloom, great color !
Daughter Of Stars TB *fairly* reliable re bloom
Earth And Sky SDB reliable mid -September rebloom
Love Goes On BB VERY reliable rebloom, great iris !!
Peach Parasol BB just planted last year, so no "info" on re bloom, yet
Purple Joy SDB One of the most reliable I grow
Twiggy BB *fairly* reliable re bloom.....but worth having for "spring only" bloom...it's a nice one
Zee TB Reblooms here, but most of the stalks freeze out.........our usual "Killer frost" is around the first week of October. "some" of the Re's seem to take a lot of "killing freeze" to stop them.....this isn't one of them!
In years when I had the ambition to cover, or otherwise protect the ones with stalks / buds, I have extended the bloom for a week, to 10 days....but the last several years, I just let Mother Nature take her course !
