Jane, my Hosta's are a foot high..... they will freeze for sure. I have small fruit on my plum trees and I don't know what will happen to them.
Some of my hyacinths are through so I don't worry about them too much. Here is a photo today of a TB in front of tulips.
Gardeners have to be able to take brutal weather, plagues of eating insects, diseases and loss in stride. So many of my taller irises already have tall bloom stalks. I may only have damaged blooms out of them. :shrug:
That is why we need many, many irises. We need ones that bloom early and late. We need so many that there is no way we can get sad during bloom season.
