Oscularia pedunculata is a succulent groundcover with blue-gray foliage that reaches up to 1 foot (30 cm) tall and spreads up to 3 feet (90 cm) wide. The leaves are fleshy and 3-angled. The flowers are purplish-pink, pinwheel-shaped, up to 1.2 inches (3 cm) in diameter, and appear in late spring into early summer. They open fully as the afternoon approaches.

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 the way they need to be treated in cultivation.
The basics of care are very simple, with 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' own adaptability and to follow their growth habits in your particular conditions.
These plants require a loam-based compost with the addition of 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. There are some Mesembs that begin to grow in the fall as the temperature drops and the days get shorter. See more at How to Grow and Care for Mesembs.
Oscularia pedunculata is native to South Africa.
