Description
Bergeranthus vespertinus is an almost stemless succulent with small, finely tapered leaves crowded into rosettes. It grows up to 2.4 inches (6 cm) tall and up to 1 foot (30 cm) wide, forming a flat compact mat. Leaves are erect at first, later more or less prostrate, and up to 2.4 inches (6 cm) long. The leaf surface is grey-green with some darker dots and rather wrinkled. Flowers are yellow, up to 2 inches (5 cm) in diameter, and appear on long, branching stalks.

Hardiness
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
The basics of Mesemb 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' adaptability and follow their growth habits in your particular conditions.
Mesembs 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. Some Mesembs begin to grow in the autumn as the temperature drops and the days get shorter.
Because different genera within the Mesemb family have different growing conditions, care must be taken with watering. Some genera will benefit from light spray water to prevent shriveling during their dormant period.
