Little Treasure White Rock Cress

Little Treasure White Rock Cress (Arabis caucasica 'Little Treasure White')

Little Treasure White Rock Cress is a low, evergreen groundcover that turns sunny edges and rock gardens into a bright spring carpet. It spreads into a tidy mat that helps finish borders, cover bare soil, and soften hard lines without feeling heavy. In spring, masses of small white flowers blanket the foliage and bring an early lift when the garden still feels sparse. Once established, it handles lean soils and dry stretches well as long as drainage stays sharp.

Distinctive Features

This compact selection forms a mounding cushion of gray-green evergreen leaves and produces clusters of sweetly fragrant, four-petaled white flowers in spring. The bloom display can be dense enough to nearly hide the foliage, creating a clean, bright band of color along paths and at the front of beds. Its habit stays low and controlled, making it easy to use in repeated drifts for a cohesive look. Good drainage is the key, especially in winter, because wet soil can shorten its life.

Growing Conditions

• Sun: Full sun to part shade, with best flowering in full sun.
• Soil: Gritty, sandy, or average well-drained soil, and avoid heavy, waterlogged ground.
• Water: Low to medium, water to establish, then water during extended drought.
• USDA Zones: 3 to 7.
• Mature Size: About 4 to 6 inches tall and 10 to 12 inches wide.
• Notable Traits: Evergreen foliage, fragrant spring flowers, and generally deer and rabbit resistant.

Ideal Uses

• Focal Point: Mass it along a path edge so the spring white flower carpet becomes a crisp focal point that reads from the house.
• Rock Gardens: Tuck into crevices and gravel beds where drainage is fast and the habit stays tight.
• Border Edging: Use at the front of sunny beds for a clean, low line that looks finished.
• Slopes and Banks: Plant on inclines to help cover soil and add spring color where mowing is awkward.
• Wall and Step Edges: Let it spill slightly over stones to soften hard surfaces with evergreen texture.

Low Maintenance Care

• Shearing: Shear lightly right after flowering to keep the plant dense and prevent a leggy look.
• Watering: Water consistently the first season, then reduce and avoid soggy conditions.
• Drainage: Improve heavy soil with grit or plant in raised areas to protect the crown in winter.
• Weed Control: Keep young plants weed-free until the mat fills in and suppresses competition.
• Rejuvenation: Replace older patches if vigor declines, since tight, well-drained sites keep it at its best.
