From a biblical place name. The derivation is from the phrase ‘I am the rose of Sharon, and the lily of the valleys’ (Song of Solomon 2:1). The plant name ‘rose of Sharon’ is used for a shrub of the genus Hypericum, with yellow flowers, and for a species of hibiscus, with purple flowers. Sharon is recorded in the United States from the 18th century, as a name of both boys and girls. Since the 20th century, however, it has been used predominantly if not exclusively for girls.
