Another amaryllis from a Christmas past! This is a lovely deep rose.
I don't know for sure but this unexpected bloom may be due to banana water. I've been putting banana peels in a gallon jug of water then. after they're rotting and the water is quite disgusting, I pour the potassium-rich liquid onto various pot plants. The amaryllis were some of the first recipients of this homemade fertilizer.
I needed to experiment further . . .
