(Begonia × tuberhybrida) Tuberous begonias
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.
Cultivation
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.
