I don't know - how long have you had it and where is it growing?

they dont flower at this time of year unless ou mean an amaryillis.

I'm assuming that it what Guest means, Seaburngirl!

If it's one left from Christmas 2008, and hasn't received the right treatment, it may need another year of better culture and gathering energy before it can bloom. That's assuming it is an amaryllis (Hippeastrum).
