The bromeliad plant was very abundant in El Yunque rain forest before Hurricane Maria 140 MPH winds in 9/20/17 ravaged the forest canopy and affected all minor plants and many trees. It stores water for insects and frogs, like the coqui, and serves are their home! It mostly hangs on tree trunks and branches and needs to ground to grow - its an air plant. They can be micro size to large - over 4 feet. This depends on the wind and altitude.
