Begonia davisii

It was discovered by the Victorian plant collector Walter Davis (after whom it was named) near Arequipa in Peru and was first introduced to England in 1877.[3][4]

Description

The plant has a dwarf, tufted habit[4] with broadly ovate–cordate leaves, which are glossy bluish-green above and purplish beneath, with a slightly lobed serrated margin; the flowers are rich orange-scarlet in colour, arranged in threes on erect red-coloured scapes 6 inches (150 mm) to 8 inches (200 mm) high.[3]

Hybridization

The dwarf habit and erect flowers characteristic of this species were taken advantage of by John Seden, who rapidly evolved several garden forms, including a dwarf race of hybrids suitable for summer-bedding which became popular in Victorian England.[3][5]

The cultivar, B. davisii Orangeade, which has double bright copper–orange flowers, is available commercially today.[6]
