Rain lily (Zephyranthes atamasca) is a short-lived perennial wildflower that occurs naturally in slope forests, moist flatwoods, river swamps and floodplains, shaded limestone outcrops, along roadsides and in rural areas. It is a threatened species in Florida. As the common name suggests, rain lilies typically bloom after a rain shower. Flowering can occur in late winter through early summer, but their tendency to bloom around Easter has earned them another common name — Easter lily.

Its showy, solitary flowers are white (although sometimes tinged with pink), and have bright yellow stamens and 6 distinct lobes that unite at the base to form a funnel. They are born on leafless stalks. Leaves are basal, and linear or grasslike in shape. They arise in clumps.

Garden tips: Although rain lilies prefer moist soils, they do not do well in soils that are constantly saturated. They can, however, withstand sustained drought. They are a very hardy species and are a great replacement for the many non-native lilies that are commonly sold in big box garden centers. They make for a nice mass planting, and also work well in lawns as they can be mowed. Rain lilies can be propagated by seed or division of bulbs.

Caution: All parts of this plant are poisonous if eaten.
