Iberis, commonly called candytuft, is a very hardy perennial that has been used in gardens for many years. It is an early blooming, vigorous perennial that is semi evergreen in our zone (5-6). The cultivar 'Alexander White' is a compact, very floriferous plant, which typically is 6-8" tall, spreading to 18" wide. Large profuse clusters of pure white flowers often obscure the glossy dark green foliage in mid to late spring. This perennial prefers well drained soil in full sun, and is drought tolerant. It makes an excellent edging plant, or can be used in rock gardens or cascading over a wall.
