Zephyranthes atamasca (L.) Herb.
Atamasco lily, Rain lily
Liliaceae (Lily Family)
Synonym(s): Amaryllis atamasca, Atamosco atamasca, Zephyranthes atamasca var. atamasca
USDA Symbol: ZEAT
Atamasco-lilies are small, colony-forming perennials, 8-15 in. tall, with thick, shiny, grooved, grass-like leaves forming loose clumps. Solitary flowers are borne on leafless stalks. The showy flowers are white (rarely pink), with six distinct lobes, united to form a funnel. They turn pink with age. From an underground bulb grow several flat leaves; leafless flowerstalk, usually single and about as tall as the leaves, bears white lily-like flower, tinged with pink.
The genus name alludes to Zephyrus, in Greek myth the west wind and husband of Chloris, goddess of flowers. Blooming generally around Eastertime, these flowers are popularly known as Easter Lilies. The species name, derived from a Powhatan word meaning stained with red, describes the flower.
