I have a Salvia Patens. I've heard cinflicting advice as to overwintering
them. Some say dig them up before first frost and store them like dahlias.
Don't dig rhem up, but cover crown with 3" mulch or dead leaves.Would that
be enough to protect them if the temp fell consistently below freezing at
night over the winter? What would happen if we get a few weeksa of settled
snow?
