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.
PropagationPlant seeds of annuals in the garden in spring or autumn. Start perennials and subshrubs in a cold frame in autumn. Plants can also be started from softwood cuttings in late spring or semi-ripe cuttings in summer.
ProblemsDiseases are rare, but can include clubroot, damping off, gray mold, and fungal spots. Snails, slugs, and caterpillars can damage plants.
