Can Potted Hellebores Recover After Frost?

Question

These potted hellebores are inside a larger planter with soil around were left outside overnight at 27F. the temperature dropped lower than predicted and since it was not at my home (church entrance) I went there this morning and found that the flowers and leaves are ice frozen and stiff. I wrapped planters with weed fabric and burlap, but wondering if it’s not too late. the temperature will stay in low 30s during the next couple days and lower at night.

Answer 1

You are in zone 6 and most hellebores are pretty hardy, some to zone 3. Some of the hybrids are hardy to zone 5, which may not have been enough protection in a container. Let the plant thaw out on its own and chances are good it will survive. Here are growing tips:
