Denys, for many years I had a big pot of Nerine bowdenii thick with big healthy bulbs which I put out for the summer and brought indoors for the winter. By the time I brought it in for the winter the foliage had started to die down for the year, and during the winter the pot was not watered and the bulbs made no new growth. When the pot was put outside in the spring and watered well, leafy growth resumed. In all the years I had these plants, never once did they bloom.
