String lily (Crinum americanum)
Click on terms for botanical definitions.
Also known as seven sisters or swamp lily, string lily is an erect, emergent perennial with showy, fragrant blooms. Its large white flowers have no petals. Rather, they have long, linear to lanceolate tepals that are fused at the base, forming a tubelike bud. Once open, the tepals curve backwards, exposing long stamens topped by conspicuous reddish-purple anthers. Leaves are dark green and linear with finely toothed margins. Flower stalks and leaves grow directly from a bulb. Seeds are formed in capsules.
String lily is found in wet hammocks, marshes, swamps, wetland edges, and along streams and rivers throughout Florida and the southeast United States.
The bulbs and leaves are poisonous to humans, but are a favorite treat of lubber grasshoppers.
Family: Amaryllidaceae (Amaryllis family) (String lily was once placed in the Lily or Liliaceae family, but has since been moved to the Amaryllis family)

Garden tips: String lily is often confused with its cousin, the spider lily (Hymenocallis sp.) as they look very similar and grow in the same conditions. Both make beautiful additions to wet landscapes, including along retention ponds.
