Description

Rain Lily is a native onion-like perennial bulb that is native to SE USA and NC in mainly the coastal and Piedmont areas. The foliage is grass-like and may be easy to miss with no blooms. The showy fragrant trumpet flowers are white, sometimes tinged with pink in the spring. It can spread from bulb offsets to form colonies. The plant goes dormant in summer. Rain Lily was the 2010 NC Wildflower of the Year.

Easy to grow in rich moist to wet but well-drained acidic soil in sun to partial shade. Prefers some leaf mold added to the soil.

Habitat: Bottomland forests and adjacent road shoulders, wet meadows, sometimes in upland forests over mafic rocks
