About

Begonia decora is a tender conservatory and houseplant native to Malaya, grown under glass or indoors in the UK. It forms a well-branched, multi-stemmed, rounded plant and is deciduous. It prefers partial shade and a moist, well-drained loam of neutral pH. It flowers from June to October.

About the genus

Begonia is a genus of perennial flowering plants in the family Begoniaceae. 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. Some species are commonly grown indoors as ornamental houseplants in cooler climates, or cultivated outside in summertime for their bright colorful flowers, which have petals but no sepals.

In the garden

Begonia decora originates from Malaya and is usually cultivated in the UK as a conservatory, greenhouse or indoor specimen where frost can be excluded. The plant develops as a well-branched, multi-stemmed clump and sheds its foliage seasonally. Flowers appear between June and October when conditions are warm and sheltered. Position the plant in partial shade—north-, east- or west-facing windows and bright conservatory corners suit it best—and avoid full sun. Use a loam-based compost kept moist but well drained; a neutral soil pH is preferred. The exposure should be sheltered from cold winds and driving rain, so containers on a protected patio or inside a greenhouse work better than exposed beds. The UK hardiness rating H1c indicates the plant is tender and needs frost-free conditions through winter. Begonia decora adapts to pots and containers as well as protected borders in summer, making it suitable for city and courtyard gardens, patios, and cottage-style beds when moved into shelter for cold months. Take care with watering: keep the rootball evenly moist without waterlogging. As a deciduous species it will lose leaves going into cooler weather, so plan repotting or major pruning for when new growth begins in spring rather than during its rest.
