Candytuft (Iberis sempervirens) is a ground-hugging perennial flower that is frequently used as a ground cover or as edging along pathways. Its white or pink blooms brighten gardens in April and May. Candytuft plants are mid-spring bloomers, but they are worth the wait. The flowers are showy, and there are a lot of them—masses of blinding white flowers along their stems. This white is softened towards the end of the blooming period, as the central petals turn lavender. The color of the blossoms stands out nicely against the backdrop of the dark green foliage and also makes these plants good for moon gardens. The petals form a pretty pattern that never fails to hold your attention if you are willing to take a good, close-up look. One thing the flowers do not have going for them is a pleasant aroma; the scent is actually unpleasant. One popular cultivar, ‘Purity,’ can reach 10 inches in height, with a slightly greater spread. A shorter cultivar (height of 6 inches) is ‘Nana’ The well-named ‘Autumn Snow’ is a cultivar that will rebloom in fall.
