Tillandsias or Air plants are epiphytic, meaning that they live by absorbing water and nutrients through their leaves, rather than from soil. In their native Central and South America, Tillandsias grow on trees, using their small roots to anchor themselves on a tree branch. Provide bright filtered light. Soak in distilled water once a week for 2 hours. After they soak, Tillandsias need to dry out fully.
