ponytail palm is a tall, palm-like plant that is not a true palm but is closely related to agave. it has an upright, fleshy, trunk-like stem that becomes swollen at the base, where it stores water. this is topped with clusters of long, curved, sword-shaped leaves that hang down giving the appearance of a pony's tail. when mature, it produces panicles of fragrant cream colored flowers that are pollinated by bats.
