Iberis sempervirens: Evergreen Candytuft for Sunny Borders

Iberis sempervirens (evergreen candytuft) is an evergreen subshrub that 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. Makes an effective edging for a sunny border.

Noteworthy Characteristics

Very floriferous, trouble-free groundcover for a sunny site.

Care

Grow in average but well-drained soil in full sun. After flowering, lightly shear to keep 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.
