White Carpet
Dymondia margaretae
grassWhite Carpet is a low-growing, mat-forming groundcover native to South Africa, featuring fine, silvery-white foliage that creates a carpet-like texture. It reaches only 2-3 inches in height and spreads horizontally to create dense coverage, making it ideal for pathways, between pavers, and as a lawn alternative. Despite its delicate appearance, it is remarkably tough and traffic-tolerant.

Establishment
4-6 weeksYoung plugs or divisions are placed in soil with fine silvery foliage beginning to develop; plants are small and isolated
Water regularly to keep soil consistently moist but not waterlogged; apply 1-2 inches of mulch around plants (keeping away from foliage); avoid foot traffic during this period
Vegetative Growth
6-12 weeksPlants expand outward as runners develop; foliage becomes denser and silvery-white color intensifies; gaps between plants begin to close
Reduce watering frequency as drought tolerance increases; lightly rake or brush foliage to encourage spreading; maintain spacing between plants for even coverage
Maturation
12+ weeks to full maturityPlants form a complete, dense mat of fine silvery foliage; coverage becomes continuous across the planting area
Minimal maintenance required; water only during drought conditions; light foot traffic is acceptable; gently brush in the direction of desired growth if needed
Flowering
4-8 weeksTiny white or pale yellow flowers appear on thin stems above the foliage (spring to early summer); flowers are inconspicuous but add subtle visual interest
No special care needed; flowers require no deadheading; minimal impact on overall appearance or maintenance
Long-term Maintenance
Ongoing (perennial)Established plantings form a persistent, dense groundcover with minimal growth change between seasons; foliage remains low and carpet-like
Water only during extended drought; avoid herbicide drift; lightly rake to remove debris; divide congested areas if needed; tolerates moderate foot traffic

Uses
Drought-tolerant groundcover
HouseholdWhite Carpet is an excellent xeriscape plant requiring minimal water once established, making it ideal for water-conscious gardeners in arid regions. Its silver foliage reduces water needs by reflecting heat and reducing evaporation. [source]
Traffic-tolerant pathway filler
HouseholdUnlike delicate ornamental grasses, White Carpet can withstand moderate foot traffic, making it perfect for walkways, between pavers, and in high-traffic groundcover areas. It creates a soft, appealing surface without the maintenance of turf grass. [source]
Low-maintenance lawn alternative
HouseholdWhite Carpet provides a natural-looking lawn replacement that requires no mowing, minimal fertilizer, and infrequent watering once established. It's ideal for small yards, xeriscapes, and areas where traditional grass maintenance is impractical. [source]
Pollinator support
WildlifeThough inconspicuous, the flowers of White Carpet attract small pollinators and beneficial insects, contributing to garden biodiversity. Its dense growth also provides shelter for beneficial ground-dwelling insects. [source]
Ornamental silvery landscape accent
CraftThe distinctive silver-white foliage of White Carpet provides striking visual contrast in Mediterranean, succulent, and modern landscape designs. It creates a soft, cooling visual effect and complements drought-adapted plants and hardscape features. [source]
Harvest Tips
White Carpet is a groundcover, not harvested for food or propagation for sale. To propagate: divide established plants in spring or early fall by digging up sections of mat and replanting with 6-12 inch spacing; or take small plugs and transplant to new areas
Fun Facts
- 🌱 White Carpet is native to the Cape Peninsula in South Africa and has become a popular landscape plant in California, Arizona, and other drought-prone regions for its exceptional water efficiency.
- 🌱 Despite its delicate, fine foliage appearance, White Carpet is remarkably tough and has been successfully used in commercial landscapes, parks, and botanical gardens in Mediterranean climates.
- 🌱 The plant's silvery-white color is enhanced by fine hairs on its leaves that reflect sunlight, which both reduces water loss through transpiration and creates its distinctive pale appearance.
