Tillandsia is the largest genus in the Bromeliaceae family, containing approximately 630 species of bromeliads which are perennial, evergreen, flowering plants from South America and the West Indies. Commonly known as Air Plants, they are found in jungles, rainforests and arid desert environments, from sea level to high mountain regions. Usually the thinner the leaf, the more water is needed. Tillandsia can be air, rock or terrestrial plants. Always mist or water your air plants in the morning and make sure to shake off any excess water before setting them out to dry.
