Amaryllis bud

Amaryllis, tall and straight,
showing colour in your bud.
Amaryllis, straight and tall,
there's springtime in your blood.

Thanks to all who looked at my mystery abstract yesterday: it was the inside of a teapot, showing the holes leading to the spout. Congratulations to Julez who guessed the answer, and to Leah whose suggestion was the funniest and most creative!
