Iberis sempervirens, commonly called candytuft, is a low-growing, spreading, woody-based, herbaceous perennial or sub-shrub which typically forms a foliage mound rising to 6-12” tall and spreading to 18” wide or more. It is native to southern Europe. It is evergreen in warm winter climates, but semi-evergreen in cold winter climates where the foliage may become straggly or otherwise suffer significant decline in harsh winters. Small, pure white, 4-petaled flowers in dense, flattened clusters (corymbs) appear in a profuse, early-to-late-spring bloom (March-May), the density of which often totally obscures the foliage beneath. Flowers sometimes gradually age to light pink. Numerous, oblong, entire, narrow, dark green, leathery leaves (1-1.5” long).

Genus name comes from the Greek word iberis indicating a plant from Iberia.

Specific epithet comes from semper meaning "always" and folia meaning "green" in reference to the evergreen foliage of this species.

'Snowflake' forms an evergreen clump of foliage around 10" tall (when in flower around 12") with a spread from 1-3'. A blanket of white blooms appear in spring and last several weeks. This cultivar is known for its profuse flowering and consistent, dense habit. Attractive to butterflies.
