Alexander's White Candytuft

Alexander's White Candytuft (Iberis sempervirens 'Alexander's White')

Alexander's White Candytuft is a spring-blooming evergreen groundcover that delivers a clean, bright layer of white flowers right when gardens need a fresh reset. Its low, mounding habit makes borders look finished, softens hard edges, and helps tie mixed plantings together. Because the foliage stays attractive beyond bloom, it continues to add structure and a neat, green presence through the rest of the season. If you want reliable spring impact with a polished look the rest of the year, this candytuft is an easy fit.

Distinctive Features

This variety forms a dense mound of narrow, glossy evergreen leaves and becomes covered in flattened clusters of pure white flowers in mid spring. The bloom show is heavy and lasting, and many plants will offer a lighter repeat bloom later in the season when conditions are favorable. It performs best in full sun and well-drained soil, and it appreciates good airflow to keep the foliage looking crisp. The overall effect is classic and tidy, especially when it is lightly sheared after flowering.

Growing Conditions

• Sun: Full sun for the strongest bloom and tightest habit, with light shade tolerated.
• Soil: Well-drained soil is essential, and it performs well in average to lean soils that do not stay wet.
• Water: Medium moisture to establish, then low to medium once established, avoiding consistently wet soil.
• USDA Zones: Zones 3 to 8.
• Mature Size: Typically 6 to 10 inches tall and 12 to 18 inches wide.
• Habit: Low, mounding, and spreading evergreen groundcover.
• Bloom Season: Mid spring to early summer, often April to May depending on climate, with possible light rebloom.
• Notable Traits: Drought tolerant once established and often deer and rabbit tolerant.

Ideal Uses

• Focal Point: Use it as a focal point at the front of a sunny border where a bright spring blanket of white can define the bed.
• Edging: Line walks and garden beds for a crisp, evergreen border that looks neat year-round.
• Rock Gardens: Plant in well-drained rock or gravel areas where it can bloom heavily and stay compact.
• Wall and Slope Planting: Tuck into sunny slopes or along low walls to soften edges with evergreen texture and spring flowers.
• Groundcover: Mass plant to knit together sunny areas and reduce visible mulch with a clean, uniform finish.

Low Maintenance Care

• Shearing: Shear lightly right after flowering to encourage fresh growth and keep the mound tight and tidy.
• Watering: Water during prolonged drought, especially the first year, but avoid frequent watering in heavy soils.
• Drainage: Improve drainage in clay soils with grit or raised beds to reduce winter wet stress.
• Mulching: Use a light mulch to moderate soil moisture, keeping mulch off the crown to prevent rot.
• Cleanup: Remove winter-damaged tips in early spring to refresh the plant before bloom.

Why Choose Alexander's White Candytuft?

Used in drifts or as a border line, it delivers a clean, classic finish that is hard to beat.
