Genus: Oscularia
Origin
This species is native to South Africa. It grows on sandstone rocks along low mountainous regions from Ceres to George just to the north of the Cape Peninsula in the Western Cape province.
Description
Oscularia deltoides is a low-growing succulent shrub with wiry, decumbent or trailing, grey-green, often purple-tinged stems and blue-green 3-angled leaves with small, often reddish teeth. It grows up to 1 foot (30 cm) tall. Leaves are thick and fleshy, up to 0.7 inches (1.8 cm) long and up to 0.4 inches (1 cm) wide. Flowers are almond-scented, lavender-pink to purple with a yellow center, up to 0.8 inches (2 cm) in diameter, and appear in spring and summer. They are closed in the morning but open, often covering the plant, in the afternoon.
Hardiness
USDA hardiness zones 8b to 11b: from 15 °F (−9.4 °C) to 50 °F (+10 °C).
How to Grow and Care
Mesembs mostly adapt 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 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 to 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.
