Hi Gang, I have some C. bulbispermum plants in my yard. The foliage stays green all winter, even when temperatures have dropped briefly to 23 F (rising to well above freezing the next morning. Similarly, C. x powellii types are essentially evergreen. Essentially all other Crinum plants I grow are burned at 28 F and most die back completely with an hour or two of 25 F. Does anyone know at what point these plants lose their folaige to frost? Cordially, Joe Hot again today, Amarcrinum still blooming, and some odds and ends of rainlilies.
