Begonia semperflorens-cultorum /bəˈɡoʊni.ə/
Common name: Wax begonia · Bedding begonia · Fibrous begonia
Begonia semperflorens-cultorum is a hybrid group of compact, fibrous-rooted begonias derived largely from Begonia semperflorens, native to Brazil. They form tidy mounds of glossy green or bronze foliage studded with white, pink, or red flowers that bloom continuously through the season. Valued for their reliability in shade or sun, they are among the most widely planted bedding annuals in the world.
