I have 5 seedlings from bulb exchange seed. The seeds were strange black things like shiny hats, very 3-dimensional and not flat like some amaryllids. They're at least 5 years old and don't grow much. They tolerate our winters just fine (minimums have been -8C / 15F) I bring the pot into the house in the summer and keep it dry. I move the pot outside and keep it moist for the winter. Should I be fertilizing them much? I haven't. This year the leaves that emerged were smaller than last years', but maybe that is because I was late getting them out. Each plant makes only one leaf each year. Leo Martin Phoenix Arizona USA
