Amaryllis one year on - NOT amateur radio

We have several amaryllis plants this year including this one which was very successful last winter. Over the summer we did all the right things, but since October it refused to grow and just froze. My wife put it in the garden expecting it to rot and die.

I noticed a few weeks ago that it was still going, so I replanted it and brought it back inside again. Since then it has started to grow again, although we'll have to wait and see. It would be great if it took off and flowered.
