We find most bowdenii hybrids are frost hardy and can withstand a fair level of cold (-4 or -5c for a week or so) (that seems to be the extent of our winters here nowadays). There is a perception that the newer Dutch hybrids are more tender and there are trials being undertaken at various sites in the UK to see which are toughest. Ken Hall, the great expert here, grows them in south-facing beds and other successful growers also plant near walls. His bulbs are completely covered with soil and some mulch. I think the best way is to avoid prolonged freezing conditions, especially if they are in pots, I wouldn't put them in your drawing room (too warm) or a cellar (too dark), they need light in winter as they should have leaf growth then, a garage or porch perhaps, where they come from has cold nights and warmish days.

Dear Fellow Horticulturists, This spring I purchased a half dozen bulbs of Nerine bowdenii, and am very happy with them. I have them in a pot on my back porch. I read they are hardy, but haven't found any other details on their hardiness. We are here in USA Zone 4 = Canadian Zone 3A, just across the border from Madawaska, Maine. Should I unearth them, let them dry, then store them in dry peat moss in my cool cellar? Should I simply bring in the pot and position it in my living room at about 20-22 C? I'll be grateful for any advice. Sincerely, JDBourque Saint-Jacques, NB CANADA ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
