Could someone with experience growing Amaryllis belladonna tell me if it's common for this species to skip flowering after cold winters? I've had bulbs in my yard for 3 years, flowering for two of them, Last winter was colder than usual for this area, with lows around 14 F. Foliage died back during the snow, came back after the coldest weather was past, then died down in late spring. Then summer came, and came further, and still, in August, no flowers. The bulbs came from a local garden where they'd grown for many decades, and without skipping flowering, year after year. Kathleen
