In many types of bromeliads the thick, broad leaves form funnel-shaped rosettes called tanks, which hold water. Many bromeliads also develop beautiful flowering stalks. Epiphytic plants do not live in soil but survive by clinging to a tree or other supports such as rocks. Epiphytes are not parasites. They do not harm the host plant in any way, but merely use them for support.
Epiphytes obtain all their water and mineral needs from the air.
Epiphytic bromeliads can be either grown in soil or mounted on a board, branch, shell or various other surfaces. They must be firmly attached. Terrestrial bromeliads require soil for growth like most other houseplants. Bromeliads need strong light to grow well and produce flowers. Most bromeliads require filtered light, with a few exceptions.
