Evergreen candytuft (Iberis sempervirens) eye-BEER-iss sem-per-VEER-enz Synonyms:  Iberis commutata Genus:  Iberis This evergreen subshrub slowly spreads to form a tidy cushion of shiny dark green leaves. In late spring and early summer, numerous flattened clusters of 4-petaled snow-white flowers nearly cover the foliage. Iberis sempervirens makes an effective edging for a sunny border. Noteworthy Characteristics:  This is a very floriferous, trouble-free groundcover for a sunny site. Care:  Grow in average but well-drained soil in full sun. After flowering, lightly shear the plants to keep them neat and bushy. Propagation:  Sow seed in containers in a cold frame in autumn. Root softwood cuttings in late spring or semi-ripe cuttings in summer. Problems:  Clubroot, damping off, gray mold, and a few fungal spots rarely affect plants. Also watch for snails, slugs, and caterpillars.
