Alligatorlily is a perennial wildflower endemic to cypress swamps, marshes, wet prairies, savannas and moist open flatwoods in Florida’s central and southern peninsula. It also occurs in Duval and Bradford counties and is sometimes found in roadside ditches. Its striking white flowers are primarily pollinated by Sphinx moths.

Alligatorlily’s fragrant flowers are solitary and terminal. They have three linear petals and three petal-like sepals, all of which radiate from beneath a thin, white, funnel-shaped corona. The corona is marked by faintly toothed margins and a greenish “eye” in its center. Leaves are basal, linear or straplike and can grow up to 16 inches in length. Stamens are long and prominent with large noticeable anthers. Seeds are green, egg-shaped and relatively large (up to ¾-inch in diameter).

The genus Hymenocallis is from the Greek ὑμήν (hymen), meaning “membrane,” and καλός (kalos), meaning “beautiful,” and refers to the corona. The species epithet palmeri honors British botanist Edward Palmer.
