White Out Candytuft

White Out Candytuft (Iberis sempervirens 'White Out')

White Out candytuft is an evergreen groundcover that turns into a sheet of bright white bloom in spring, instantly making beds look crisp and finished. Its low, spreading habit is ideal for edging, rock gardens, and cascading over walls without getting tall or messy. The glossy green foliage stays attractive beyond bloom, giving you structure year-round in many climates. If you want a reliable spring show with clean evergreen texture, this plant is an easy fit.

Distinctive Features

This selection produces dense clusters of small, pure white flowers from mid to late spring, often covering the foliage at peak bloom. The plant forms a compact, mounded mat of narrow, dark green leaves that are evergreen to semi-evergreen depending on winter conditions. It performs best in sun and sharp drainage, and it tolerates lean soils once established. A light trim after flowering helps maintain a tight, rounded shape and can improve the look of the foliage through summer.

Growing Conditions

• Sun: Full sun to part shade, with best flowering in full sun.
• Soil: Well-drained soil, including sandy or gravelly sites, and avoid heavy soil that stays wet in winter.
• Water: Low to medium water, watering to establish, then watering during extended drought for best foliage quality.
• Zones: USDA Zones 3 to 8.
• Mature Size: Typically 8 to 12 inches tall and 12 to 18 inches wide.

Ideal Uses

• Focal Point: Mass it along a sunny edge so the spring white bloom reads as a clean, high-contrast highlight.
• Edging: Creates a crisp border line along paths and bed fronts with evergreen texture.
• Rock Gardens: Thrives in sharp-draining pockets and adds a bright spring layer among stones.
• Walls and Slopes: Works well where stems can soften edges and stabilize a sunny, well-drained bank.
• Containers: Adds spring impact and evergreen structure in pots with excellent drainage.

Low Maintenance Care

• Pruning: Shear lightly right after flowering to keep the plant compact and encourage dense growth.
• Watering: Water during prolonged drought in the first season, then only as needed once established.
• Drainage: Improve heavy soil with grit or plant slightly high to prevent winter wet stress.
• Mulching: Mulch lightly to reduce weeds, keeping mulch off the crown to avoid excess moisture.
• Winter Cleanup: Remove winter-damaged foliage in early spring to refresh the evergreen mound.
