I brought home a leftover centerpiece from work which had these brown swirly twigs stuck in it to add decoration. My father thought they looked cool and stuck them in with his bamboo plant and one of them started to turn green, grow in height, and sprouted leaves! The other stayed brown and dead. Can you please help identify this plant?
