Tillandsia , commonly known as air plant is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae. Originating from Central and South America and the West Indies, they thrive in a diverse range of climates and environments including humid and tropical climates in rainforests, high elevation mountainous regions, deserts and swamp lands. Most Tillandsia species are epiphytes, meaning they normally grow without soil while attached to other plants, while others are aerophytes - air plants, which have no roots and grow on shifting desert soil. Most species absorb moisture and nutrients through the leaves from rain, dew, dust, decaying leaves and insect matter.
