Brassicaceae
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 characteristics:  Showy, abundant, sometimes fragrant flowers.                
Care:  Choose a site in full sun with moist but well-drained, neutral to alkaline soil of poor to moderate fertility. Prune after flowering.
Propagation: 

Plant 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.

Problems: 

Diseases are rare, but can include clubroot, damping off, gray mold, and fungal spots. Snails, slugs, and caterpillars can damage plants.
