Amaryllis is a monotypic (only one species) genus of plant also known as the Belladonna Lily or naked ladies. The single species, Amaryllis belladonna, is a native of South Africa, particularly the rocky southwest region near the Cape. It is often confused with the Hippeastrum, a flowering bulb commonly sold for blooming indoors.

In popular culture
The scientific name Amaryllis is taken from a shepherdess in Virgil's pastoral "Eclogues," from the Greek αμαρυσσω (Latin amarysso) meaning "to sparkle."[2]
It is used as a given name for females.
