Taxonomy

Tillandsia usneoides, also known as Spanish moss, is an epiphytic plant that grows on trees in tropical and subtropical climates. It is native to Mexico, Bermuda, Central and South America, the Southern United States, and West Indies, and has been naturalized in Australia. Despite its name, it is not native to Spain. Commonly found on the southern live oak and bald cypress in the mid-Atlantic and southeastern states of the US, it is also known as Black Moss, Vegetable Horsehair, Long Moss, Tree Hair, and Spanish Beard. It can grow up to 25 feet in length. As an air plant, it is easy to care for and does not require soil or a pot. Spanish Moss is a popular houseplant that needs very little water and does best in long-lasting, direct light, ideally less than 1 foot from a window. In French Polynesia, it is called "grandpa's beard."
