Iberis sempervirens [evergreen candytuft, perennial candytuft] is a species of flowering plant in the family Brassicaceae, native to southern Europe. It is a spreading sub-shrub growing to 30 cm [12 in] high by 40 cm [16 in] broad. Cultivated as an ornamental plant often seen cascading over rocks and walls, or used as ground cover. The glossy, evergreen foliage forms a billowing mound, with many fragrant, pure white flowers.
Iberis is so named because many members of the genus come from the Iberian Peninsula. Sempervirens means “always green”, referring to the evergreen foliage.
