Description
Oscularia caulescens is a succulent groundcover with blue-gray foliage that grows up to 1 foot (30 cm) tall with a spread of up to 3 feet (90 cm). It has wiry dark pink stems and fleshy, blue-green, 3-angled leaves. Flowers are bright pink, pinwheel-shaped, up to 1.2 inches (3 cm) in diameter, and appear from spring to mid-summer, opening fully as afternoon approaches. They are pleasantly scented with the stamens white at the base and pink near the tips, arranged upright in a cone-like formation in the flower center.
Hardiness
USDA hardiness zones 8b to 11b: from 15 °F (−9.4 °C) to 50 °F (+10 °C).
How to Grow and Care
Mesembs are mostly adapted to relatively predictable rainfall patterns rather than extreme drought and irregular rainfall. Total rainfall may be extremely low, but water is available at least seasonally or through fog and condensation. This leads to or allows plants that are not especially large and sometimes very small and affects how they need to be treated in cultivation.
The basics of care are very simple: free-draining soil, plenty of sun and ventilation, and regular light watering in the right season. Yet the difficulties are endless, trying to adapt to the Mesembs' adaptability and follow their growth habits in your particular conditions.
These plants require a loam-based compost with extra drainage material such as horticultural grit or perlite. They all like good light conditions and plenty of ventilation.
Some are relatively cold-hardy and can even survive mild winters outside. Most will survive temperatures down to the freezing point. Some Mesembs begin to grow in the fall as the temperature drops and the days get shorter.
