I live in Kansas and we are supposed to get a late freeze tonight. I planted 10 coral bells last year and because we had a lot of very warm days starting in mid March which continued into April, fairly normal here. The weather most of April has been very warm, 80s. So everything is growing like gangbusters. They are in a bed against the front my home, a north facing home. Will my coral bells survive this late freeze without being covered? I also planted 3 columbines last year which are already blooming so I am going to cover those.
