I can vouch for that fact, Chuck. We had some pretty warm weather early in the year and then in mid-late March two or three nights in the high teens...hard freezes. Our tall bearded irises that have been in the ground from one to four years had broken dormancy and several show freeze damage. Some were damaged pretty badly, some a little, and some have no evidence of damage on the foliage. It would seem that the more heavily damaged ones had broken dormancy earlier, and were in a growth stage that made them somewhat juicier that the others. I suppose genetic makeup determines when they break dormancy. Daylilies are registered as being dormant, semi-evergreen, or evergreen. Many of those hybridized in Florida and other southern zones just won't grow here, or if they grow at all, they struggle. I can't correlate the damage in our irises to the areas they were hybridized at all, though. One that is somewhat damaged and has pale foliage at the moment was hybridized in Kentucky. Others that show no damage at all are from west coast hybridizers. Curious phenomenon.
Have others on the list had freeze damage in similar circumstances this year?
Our "Freeze Queen Linda" has collected a lot of data on irises that survive in her garden in Tennessee, but her problem is every year. Ours happens once in a great while.
