Tillandsia caput-medusae is a species of flowering plant in the bromeliad family, Bromeliaceae, subfamily Tillandsioideae. Common names include octopus plant and medusa's head. An epiphyte is native to Central America and Mexico.
This species is a flowering air plant from the bromeliads family and is one of the most popular of the Tillandsia genus. The Caput Medusae is a very strange looking specimen that is unlike many indoor plants in looks and how it's grown. In their natural habitat they grow on trees (epiphyte) with a very small amount of roots, which help the plant to become established rather than feed or absorb water. While most plants absorb nutrients and water from roots these take the majority of them from the air (which is why they are named air plants) through the leaves. Scales (trichomes) on the leaves absorb water from humid air and air-borne nutrients.
