Begonia × tuberhybrida

Tuberous begonias (Begonia × tuberhybrida Voss, also known as the Tuberhybrida Group or the Tuberosa Group) are a group of Begonia cultivars, regarded as some of the most spectacular of the genus.

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. Another species from Peru, B. davisii (named after Walter Davis), was also used in early breeding.
