There are many species of bromeliad, including the delicious pineapple, and many flourish in America's tropics. One popular species, Aechmea fasciata, is native to Brazil and grows in areas with an average humidity of 83 percent and 45 inches of annual rainfall. At the Conservatory of Flowers, bromeliads grow in several areas of the garden, each with a slightly different habitat. Some, for example, live in the cloud forest room with orchids and ferns. There, pumps periodically release mist and the mild temperatures match what the bromeliads would experience in a natural cloud forest, 3,000 feet above sea level.
