Atamasco Lily

Zephyranthes (zeh-fir-AN-theez)

Family: Amaryllidaceae Unknown Herbaceous (1-3 ft)

Rain Lily is a bulbous perennial in the Amaryllis family that is native to southern North America south to Central and South America. There are over 70 species along with numerous hybrids and cultivars. In the wild, plants often burst into bloom immediately following periods of significant rain, hence the common name. These bulbs prefer well-drained soils in sun to part shade and bloom in spring, summer or fall depending on the species. Many bloom from summer to fall. The flowers come in white, yellow, and shades of pink. Most have grass-like foliage but some species have wider leaves. They are listed as hardy in zones 7-10 but some may tolerate colder temperatures. Use in rock gardens, borders, walkways or small spaces. They can also be used in containers and brought indoors if desired. Additional Zephyranthes Images at Juniper Level Botanic Garden
