It was well below zero several days this winter and I saw frostbite on some plants that I never even considered susceptible to the sub-temps -at least here in my yard!
Two varieties of hedges got nipped and so did some of my roses. Oh, they'll live -but I'll have to trim out the frostbite that deadened the tips.
So far, I haven't been able to claim any daylilies passed away due to the harshness of this winter but -then- most of them were covered up by the last of the falling leaves, which may have saved them.
I see little plant life *bursting forth* in my little corner of the planet....it's more like *cautiously approaching*. ;)
