Our most common variety of evergreen Iberis (Candytuft) is 'Alexander's White'. It is a low-growing, spreading, woody-based, herbaceous perennial. Semi-evergreen in cold winter climates, the foliage may suffer significant decline in harsh winters. Small, pure white, four-petaled flowers in dense, flattened clusters appear in a profuse, early-to-late-spring bloom which often totally obscures the foliage. Flowers sometimes gradually age to light pink. Excellent edging plant (many of the cultivars of this species are more compact and may make even better edgers) for borders, paths or walkways. Rock gardens or sprawl over a wall. Interesting ground cover for small, sunny areas.
