A tender wax begonia
Begonia cucullata var. arenosicola is a tender evergreen perennial with succulent stems, growing to around 40cm high. Its glossy, oval to broadly elliptic leaves have toothed, often wavy edges, and in summer it carries small clusters of white flowers touched with pink.

South American roots
The wider species Begonia cucullata is native to a swath of South America running from Bolivia through Brazil into northeastern Argentina, growing there as a subshrub or shrub in wet tropical habitats. It has since spread well beyond that range, becoming established in places as far apart as Florida, Hawaii, Korea, and several Indian Ocean islands. Within this species, this particular variety is one of several recognised botanical varieties.

Light, soil, shelter
This begonia does best in partial shade, particularly an east, north or west-facing spot that is sheltered rather than exposed. It wants fertile, well-drained soil, either loam or sand, on the acid to neutral side, and appreciates dappled or afternoon shade even though it will tolerate most positions. It is only reliably hardy outdoors in a UK summer, so it is generally grown as bedding or in containers that can be brought indoors for winter.

Seed or cuttings
Increase this plant by seed, by root cuttings, or by leaf cuttings taken in spring or summer, ideally set in a propagating case kept in partial shade.

Succulent stems, toothed leaves
The plant has a bushy, evergreen habit built on succulent stems, with rounded, toothed and sometimes wavy-edged foliage. Its size stays modest, reaching only 0.1 to 0.5 metres in both height and spread at maturity.

Watch for common pests
It can attract caterpillars, mealybugs, mites, thrips, vine weevil, and aphids, so it is worth checking leaves and stems regularly for early signs of any of these.

Grey mould and rot
The main troubles to watch for are grey mould, powdery mildew, and stem rot, all of which tend to take hold in damp, poorly ventilated conditions.

No pruning needed
This begonia asks for no pruning. As bedding or in a movable container, it is best planted out once the last frosts have passed and brought under cover again as temperatures drop.
