You're supposed to store amaryllis bulbs in the dark after they're finished for the year and then repot them after a few months' rest. Sometimes mine come back, and sometimes they don't. Last year's bloomed beautifully.* Once the leaves had finished, younger son and I boxed it up and put it in a safe place...
... which we couldn't remember. I was sad, but I bought a new bulb, which I potted in December and which bloomed in February.
Dear husband found the missing bulb a few weeks ago. We had put it in the cabinet in the downstairs bathroom. That makes sense because we also have a number of tall vases in there so it's a flower-y area. We have a wall cabinet for the things that are used more often so nobody had looked in the under-sink cabinet during the winter.
We opened the box, and the bulb had put out a very long, very white stem - and bud! The stem snaked around the small box. I planted the amaryllis in a deck pot immediately. The flowers are still opening.
It makes me happy!
(I tried to prop in up on the trellis, which actually belongs to the mandevilla** behind the amaryllis flowers, but the stubborn amaryllis didn't want to stay there.)
