Begonia annobonensis

Begonia annobonensis is a small, white-flowered begonia of the Gulf of Guinea islands (Annobón, São Tomé, Príncipe) and the Cameroon coast near Limbe. It grows at the foot of coastal cliffs, in crevices of volcanic rock near the sea, on walls and on road banks, and one label records it as an annual herb. Grow it warm and humid in bright shade, and keep seed going in case plants are short-lived.

Where it grows wild

Labels describe the base of coastal cliffs with some tree cover, crevices in volcanic lava at the shore, basalt cliffs behind a seawall shaded by trees with water seeping through cracks, stony places by a river, primary forest on rocky ground with small caves, walls of old buildings, road banks and banks in cacao plantations.

Recorded elevations are 0–35 m. Nearly all records are from near sea level.
