Rain Lily (Zephyranthes atamasco) is a long-lived perennial flower. Showy, white flowers grow in clumps, bloom late winter to spring and may reach a height of 2-3 feet. Just as it name implies, rain lily will also bloom after it rains! Plant it in full sun to part shade in dry to moist loam or sand. Best used in a mixed flower bed or edging, it is a great nectar source and will attract pollinators.
