Helen - Sorry to hear that your hostas got hit by frost. I was at a few local nurseries yesterday. The hostas at one nursery were hit by frost and looked terrible. A second nursery, which sells their plants out of a protective structure had gorgeous hostas. I was tempted to buy a second 'June' until I remembered that I had seen a HVX infected hosta there about two years ago.
ViolaAnn - I hope your hostas did not get hit. I've been spared so far.
