Introduction
Many of these photos are by Amante Darmanin, who took them in the field in South Africa. Cotyledon is a genus of succulent plants, many from South Africa. Cotyledon orbiculata is a variable species that can grow to more than 1 m tall as a shrubby plant, or it can remain small. It typically flowers in July–August, during winter in southern Africa.
The Details
Cotyledon species have gray-green leaves (sometimes up to 13 × 7 cm) that naturally develop a white, powdery coating (farina) on their surfaces. This farina helps reflect sunlight and conserve water. If a leaf surface is brushed or lightly disturbed, the farina smudges; rain usually does not dislodge it.
In winter, C. orbiculata bears orange-red to salmon, bell-shaped, pendant flowers. Cotyledon orbiculata is a popular hobby plant, and many varieties are in cultivation.
