United Kingdom 
I have three beautiful Ismene zwanenberg plants in full bloom just now,would like to know about their after care, over wintering etc.They arrived as bulbs, and I don't want to risk leaving them out in their pot over winter, as I don't know if they are hardy. Does any one out there know??? Many thanks. Sylvia.

No they're not, nothing under 15 deg C, so will need lifting, drying off and storing somewhere frost free over winter, and then repot in late winter/early spring indoors, place outside when all risk of frost is past.
