Alexander's White Evergreen Candytuft

Alexander’s White is a compact, mounding evergreen candytuft with deep green foliage and dense, pure-white flowers in spring. Its low habit suits sunny borders, path edges, rock gardens, containers, and small groundcover plantings. ## Plant Profile This named selection is Iberis sempervirens ‘Alexander’s White’. Darwin Perennials describes its evergreen foliage and dense white spring flowers; the Missouri Botanical Garden notes that the cultivar is more compact and more floriferous than the species. Mature-size references vary: the breeder lists 10–12 inches tall by 8–10 inches wide, while the Missouri Botanical Garden lists 6–9 inches tall by 6–18 inches wide. The breeder gives USDA zones 3a–8b; the Missouri Botanical Garden lists 3–8, while Illinois Extension lists 4–8. ## Growing Conditions Plant in full sun and provide well-drained soil. Illinois Extension recommends moist soil and warns against dry sites, while the Missouri Botanical Garden describes the plant as drought tolerant; reliable drainage is important because wet soil can lead to crown rot. Foliage is evergreen in warm-winter climates and may be semi-evergreen or suffer winter desiccation in colder areas. The flowers are white and may age to pale pink. ## Maintenance After flowering, trim stems by about one third to encourage fresh growth and maintain a compact shape. Stems may root where they touch the ground.
