Silver Carpet (Dymondia margaretae)

A Shimmering, Drought-Tolerant Solution for Pathways and Beyond

Introduce texture, contrast, and resilience to your landscape with Dymondia margaretae. Often called “Silver Carpet” due to its unique appearance, this durable perennial groundcover is a favorite among water-wise gardeners and landscape designers alike.⁴

At first glance, Dymondia appears to be a solid mat of silver. This stunning effect is caused by its narrow leaves, which are grey-green on top but feature a fuzzy, bright white underside.⁵ The leaves curl slightly upward, exposing the white bottoms and creating a two-toned, shimmering effect that brightens sunny garden spots.

Why Growers Love Dymondia

This plant isn’t just about looks; it is a functional powerhouse in the garden:

• The Perfect “Living Grout”: Dymondia is widely considered the best plant for filling the gaps between stepping stones, flagstones, and pavers. It grows incredibly fast flat against the ground (rarely exceeding 2 inches in height) and can tolerate light to moderate foot traffic, softening the hard edges of your stonework.

• Extreme Drought Tolerance: Native to the coastal regions of South Africa, Dymondia is built for dry climates.⁶ Once its root system is established, it requires very little supplemental watering, making it ideal for xeriscaping in arid zones.

• Natural Weed Suppression: Because it grows into such a tight, dense mat, Dymondia excels at shading out the soil below, making it very difficult for weeds to penetrate.

• Seasonal Color: While grown primarily for its silver foliage, spring and summer bring a welcome bonus of small, bright yellow, daisy-like flowers that sprinkle across the silver mat.

Design Ideas & Uses

• Pathways: The definitive choice for planting between flagstone walking paths.

• Lawn Substitute: An excellent, low-water alternative to grass in small areas with low traffic.⁸

• Rock Gardens: Provides a beautiful cool-toned contrast against darker rocks or mulch.⁹

• Erosion Control: Its dense habit helps stabilize soil on gentle slopes.¹⁰
