Cultivation

• Light: full sun, part shade
• Habit: 2 inches high, spreads to make a carpet like ground cover.
• Water: very drought tolerant water may be needed at higher temperatures. The deep roots act as water wells providing

water to the plant as needed. The dymondia carpet normaly appears green/silver in color but when roots are depleted and the
pant is thirsty the leaves curl and their silver undersides are exposed to view. Water as needed in the silver colored areas to uncurl the leaves and return to green/silver color.

• Cold hardiness: 20°F
• Heat Tolerance: no known
• Origin: South Africa
• Soil: Very sandy - Soil mix of 40% vegative matter, 30% red lava sand and 30% river sand. Perlite can be added to the mix as needed and provides faster growing in flats and pots.

Makes a flat, very drought tolerant ground cover and good lawn replacement in dry zones. Takes heavy foot traffic and often called living cement.
Works well as as a filler between flagstone, pavers, or stepping stones and other confined areas.
Soil retention: Excellent on slopes an hills due to the large diameter and deep root system.
