Butterfly Amaryllis – Growing

Q: I have a 20 year old Butterfly Amaryllis (Hippeastrum papilio) that has never bloomed. It has only sent out a few leaves but it did divide into seven bulbs which I have never separated. I have kept it in the shade and repotted it several times. I have tried to keep it dormant in winter and also to let it grow continually. Bulb fertilizer does not seem to have any effect. What is wrong?
