begonia

Any of about 1,000 species (genus Begonia) of mostly succulent, tropical or subtropical plants, many with colourful flowers or leaves and used as potted plants indoors or as garden plants. Begonias come in a bewildering array of cultivated varieties. The wax begonia (B. semperflorens) is the most popular for use as a summer bedding plant; angelwing begonias are characterized by their tall stems; hairy begonias have feltlike leaves. Most begonias are tender and intolerant of dry conditions; they require protection from strong sunlight.
