Iberis sempervirens, the evergreen candytuft or perennial candytuft, is a species of flowering plant in the family Brassicaceae, native to southern Europe. It is a spreading subshrub growing to 30 cm (12 in) high by 40 cm (16 in) broad. As an ornamental plant it is a spring-blooming favourite, often seen cascading over rocks and walls, or used as groundcover. The glossy, evergreen foliage forms a billowing mound, with many fragrant, pure white flowers for several weeks during spring and early summer. When grown in a garden it may require light pruning right after blooming, but otherwise plants can be left alone in fall and early spring. It is drought-tolerant once established. It prefers a well-drained site, so heavy clay soils that stay wet in winter should be avoided. It is not easily divided. Iberis sempervirens survives in USDA hardiness zones 3-9. It is hardy in most parts of the UK, surviving temperatures down to −15 °C (5 °F). Vernalization (a period of cold weather) is required for flower initiation. At least 8–10 weeks are needed at an average temperature of 5 °C (41 °F).
