Ornithogalum is a genus of perennial plants mostly native to southern Europe and southern Africa[2] belonging to the family Asparagaceae. There are some species native to other areas such as the Caucasus.[3] Growing from a bulb, species have linear basal leaves and a slender stalk, up to 30 cm or more tall, bearing clusters of typically white star-shaped flowers, often striped with green.[citation needed] The common name of the genus, Star-of-Bethlehem, is based on its star-shaped flowers, after the Star of Bethlehem that appeared in the Biblical account of the birth of Jesus.
