The pink family is large and of cosmopolitan distribution, comprising over 1750 species in 70 genera.
Most species are herbs or sub-shrubs.
Very many species and cultivars of Dianthus L., the carnations, pinks, and sweet williams, are available from seed merchants, nurserymen, and florists. Gypsophila L. species and cultivars are also popular for floral arrangements and bouquets, and are commonly grown as decorative garden plants. Several members of the family are known for their saponin content. The genus Saponaria L. was named for its soap-like properties. Irritant and possibly allergenic properties have been ascribed to saponins in members of this family but no detailed studies have been reported.
