I bought some Leucocoryne bulbs in Spring of 2006 and potted them up and put them in the cool greenhouse. Nothing happened. I let them cool down during Fall and Winter, making sure they did not freeze. Spring and Summer of 2007 went by with no sign of them. In October of 2007, I emptied the pots and found the bulbs, still sound and dormant. I had no idea what to do, so I decided to try them under the fluorescent lights in the basement at roughly 15C. Within two weeks, foliage was appearing above ground, and they have been growing like weeds ever since. The only thing I can figure is that they want to grow in Winter, but they can't grow at temperatures in the 5C range, which is what we get here in Winter. I don't understand why they refused to grow in Spring or Fall though. Any theories?
