Family: Amaryllidaceae

Bulbous perennial plant, deciduous in colder areas, evergreen in frost-free zones. Plants only reach a little over a foot or two tall but spread to form colonies, especially in moist soil. During summer, fragrant, white, nocturnal flowers emerge.

This plant is native to riparian areas, and can actually tolerate the marginal edges of a wetland or pond area. However they don't NEED saturated soils, and can grow in moderately moist soils such as many perennials are grown in. They can take a hard freeze down into the low twenties °F or even lower, and re-emerge from the roots. Full sun to shade (more water in the hotter locations), but don't plant where heat reflects off of surrounding walls or concrete.

Probably moth pollinated.

The genus name, Hymenocallis, comes from the Greek words hymen meaning a membrane and kallos meaning beauty in allusion to the membrane uniting the stamens. The species name, sonorensis, refers to its natural distribution in its native Sonora.

Native to wetlands and riparian areas of Sonora, and Sinaloa, Mexico.

The genus Hymenocallis contains more than 60 species of herbaceous bulbous perennials native to the southeastern United States, Mexico, Central America, the Caribbean, and northern South America.
