Last night was a hard frost. All the long leaves of nicotiana plants drooping from the shock. I think they've probably all reseeded themselves, so don't care if they appear to die back. Not sure if the lemon balm will survive in its pot, I'll shelter that one when snows come. The only other plant outside was my ginger. I should have brought it in last week. It collapsed. I've brought it in to dry out and overwinter. Cutting the foliage for the compost, sharp scent arises.
