storksbill, any of several flowering plants of the genus Erodium, in the geranium family (Geraniaceae), of worldwide distribution. Many species are wild flowers useful in garden borders and rock gardens; some are used for forage; and a number of them are weedy. The common names refer to the five-parted long, bill-like capsules, which contain the seeds.
The name storksbill is also sometimes applied to Pelargonium species, the common geraniums of greenhouse and garden (see geranium).
