Bromeliad;A bromeliad is a tropical plant in the pineapple family (the family Bromeliaceae). Some bromeliads are brightly-colored epiphytes, which live on the branches and trunks of rainforest trees. They have a remarkable way of getting water and food. Their long, curved leaves overlap at the base, forming a tight little bowl -- a perfect water tank! The leaves act as gutters to collect rain, and the tank holds the water.
