Amaryllis

My amaryllis is 13 years old.  It's bloomed at least once each year since I bought it as a gift for someone else.  I kept it instead of giving it away since by the time I was ready to put it in a package it had already started growing leaves.  I think the secret to it's longevity is bad housekeeping.  First I lost the instructions for it's care.  Then after it bloomed and the leaves died back it looked really bad.  Instead of tossing the bulb and dirt, I just placed the plant in my bathroom.  It languished there in the dark for awhile until I noticed it was putting out a leaf again.  Quite a few times, I thought the plant was dead but each time it rejuvenated.  A few years ago I came across the instructions I'd received w/ the bulb and read that I had been doing everything wrong in amaryllis care and feeding.  I also have said I need to repot it sooner or later but now I no longer have a choice.  I noticed the plant had created a second bulb and now it looks like there may be a third.  The issue is that the top of the original hard plastic pot is no longer a circle but an oblong deformed by the outgrowth of the plant.  It's amazing.
