We had a snow storm on May 12th!!!
The temps didn't get terribly low, and there was enough snow to create a layer of insulation.
Some of the plants did lose a few outer leaves but no serious damage.
THEN, a week later, we had a night with more severe frost temps!!!
Some of the roses lost the majority of their leaves, and look a bit bedraggled now.
We have had a cold spring, and it is time to begin summer!!!!
