The plant is hardy in USDA zones 3 through 9, making it versatile for various climates.
Care for Iberis sempervirens 'Alexanders White' involves moderate watering, allowing the soil to dry somewhat between waterings to prevent root rot. It prefers alkaline to neutral pH levels and benefits from pruning after flowering to maintain its shape and encourage reblooming. This cultivar is particularly valued for its early spring blooms, which create a stunning carpet of white flowers, attracting pollinators and enhancing biodiversity.
For businesses, Alexander’s White Candytuft offers excellent resale potential due to its popularity in rock gardens, borders, and as a ground cover.
