In the genus Iberis are several dozen species of annuals, perennials, and subshrubs with white (or sometimes pink, purple, or red) 4-petaled flowers that are sometimes fragrant. Candytuft is useful as bedding, in the border, in a rock garden, or in containers, depending on growth habit. These plants are native to chalky, open areas in southern Europe, North Africa, northern Iraq, Turkey, and other regions.
Noteworthy CharacteristicsShowy, abundant, sometimes fragrant flowers.
CareChoose a site in full sun with moist but well-drained, neutral to alkaline soil of poor to moderate fertility. Prune after flowering.
