Tuberous begonias (Begonia × tuberhybrida Voss) are a group of Begonia cultivars, regarded as some of the most spectacular of the genus.[3] [4]
One of the first hybrids produced was B. x sedenii in 1870, a cross between B. boliviensis, collected by botanist Richard Pearce and a species from the Andes.[5][6] Another species from Peru, B.davisii (named after Walter Davis), was also used in early breeding.[6]
Varieties common in garden centres include Betula tuberhybrida pendula or simply Betula pendula with hanging flowers and strong smelling Betula tuberhybrida pendula odorata or simply Betula odorata.
Tuberous begonias grow best in partial shade or filtered sunlight. Excessive exposure to sunlight can result in burnt flowers and leaves. However, too much shade will result in lush foliage and few flowers.
