I am wondering just how hardy my native woodland plants are. My solomons seal are showing spikes about half inch out of the ground ans I am guessing the Jacks are on the rise also. We had four inches of snow fall and melt with continued below freezing temps each evening. I also have astilbe, bleeding hearts, ferns, etc I am worried about. What is the prognosis on my garden? I will be so sad if I lose me woodland garden.
