The genus contains more than 2,000 different plant species, distributed primarily across tropical and subtropical regions of Africa, Asia, and Central and South America, with Africa considered the center of origin.

In the garden

Begonia Semperflorens Cultorum Group double-flowered is grown primarily as a conservatory or houseplant where its double flowers can be shown to best effect. The plant has a multi-stemmed, rounded habit and deciduous leaves, and it flowers from June to October, providing a sustained display through the summer months. Choose a sheltered spot with partial shade and an aspect towards the north, east or west rather than direct south-facing sun. Use a loam-based compost or soil of neutral pH that retains moisture without becoming waterlogged; the species prefers to be kept moist but well drained. Avoid exposed, windy positions where foliage and flowers can suffer. Hardiness is classed H1c, meaning the plants are tender and should be kept frost-free—either in a cool greenhouse or as indoor container subjects during winter. They suit city and courtyard gardens, patios and containers, cottage or informal borders and flower beds where a sheltered, shaded position is available. Double-flowered types produce fuller blooms over the June to October season, making them particularly effective for container displays and conservatory staging.
