Air plants are epiphytes – meaning that rather than being stuck in soil, they attach themselves to things like trees, rocks, fences, and other structures. In trendy homes, they attach themselves to seashells and driftwood and find shelter inside of terrariums. Air plants are native to the West Indies, Mexico, and much of Central and South America. In the United States, they grow in California, Florida, Georgia, Louisiana, Texas, and other southern states. There are more than 600 varieties of air plants.
Since most homes don’t mimic the natural environments from where Tillandsia usually live, the plants require occasional misting and dunking. And they love dirty water full of goodies. Their favorites include water from lakes, ponds, aquaria, rain barrels, and even bird baths. They do not appreciate distilled water at all; and tap water should be left out overnight to allow any chlorine, etc to dissipate.
