BAREROOT: LUCKY BAMBOO WITH CURL
Lucky bamboo plants need indirect light to thrive, and at least some of their cells must know this because the stalk of the plant grows in the direction of the light. The trick to "curling" the stem is to manipulate it's growth pattern, using light, until it has wound itself into a circle.
The plant grows in wet, shady places and flowers from the end of March to July, fruiting from April to September. It generally grows emerged, but can sometimes be completely submerged.
