Silver Carpet
Dymondia margaretae
grassSilver Carpet is a low-growing, mat-forming groundcover native to South Africa, known for its fine, silvery-green foliage and tolerance of foot traffic. It grows only 2-4 inches tall and creates a dense, attractive carpet without requiring mowing. This hardy perennial is increasingly popular as an alternative to traditional lawn grasses in water-conscious landscaping.

Establishment
2-3 weeksYoung plugs or divisions are planted; foliage is sparse and silvery-green
Keep soil consistently moist but well-draining for first 2-3 weeks. Protect from foot traffic during this period. Mulch lightly around plants if needed.
Vegetative Growth
4-8 weeksPlants begin spreading laterally, creating dense runner growth and filling in gaps
Gradually reduce watering as drought tolerance develops. Ensure excellent drainage. Taper off fertilization—Silver Carpet thrives in poor soils.
Mat Development
4-6 weeksDense, interconnected mat forms; foliage becomes thicker and more uniform
Introduce light foot traffic to encourage compaction and lateral spread. Water only during extended dry periods. No fertilizer needed.
Maturity & Maintenance
Ongoing (perennial)Full carpet coverage achieved; plant is drought-tolerant and traffic-resistant, with fine silvery-green foliage
Water only during severe drought. No mowing, deadheading, or pruning required. Tolerates moderate foot traffic. Weeds can be hand-pulled from young plants; mature carpet suppresses them.

Uses
Low-maintenance lawn alternative
HouseholdSilver Carpet replaces traditional turf grass, eliminating mowing, fertilizing, and reduces water consumption by up to 80% compared to conventional lawns. Ideal for xeriscaping and water-conscious regions. [source]
Walkway and pathway coverage
HouseholdThe plant tolerates moderate foot traffic and creates an attractive, soft-textured surface for garden paths and between stepping stones. Safe and comfortable for barefoot walking. [source]
Pollinator habitat
WildlifeSilver Carpet produces tiny white flowers that attract bees and beneficial insects, supporting pollinator populations while maintaining ornamental appeal. [source]
Heat and drought adaptation
HouseholdNaturally adapted to arid and semi-arid climates, Silver Carpet thrives in hot, dry conditions with minimal supplemental water once established, making it ideal for challenging garden sites. [source]
Harvest Tips
Not typically harvested. For propagation, divide established plants by digging sections with roots and replanting at soil level, best done in spring or early fall. Water new divisions moderately until established.
Fun Facts
- 🌱 Silver Carpet was introduced to cultivation from South Africa and is named for its fine, silvery-colored foliage that shimmers in sunlight.
- 🌱 Unlike grasses, it produces tiny white flowers on delicate stems and technically regenerates from seed rather than from rhizomes, making it a unique groundcover option.
- 🌱 One of the most drought-tolerant groundcovers available, requiring 80-90% less water than conventional turf grass in established landscapes.
