Botanical Name

BEGONIA( Tuberhybrida Group)

Plant Common Name

Tuberous Begonia

General Description

This collection of tuberous begonias is characterize by big, camellia-like blossoms on an upright bushy plant. The plants are hybrids derived from mountain-growing species native to the South American Andes. Plants arise from winter-dormant root tubers and flowers come in all colors except blue. These grandiose flowers are often double in form, appear in summer, and are set among open, succulent stems across the plant. They are produced in a cluster of three buds, with two smaller female flowers next to the larger, usually double and showier male flower. Sometimes the Tuberhybrida Group is loosely subdivided further into Multiflora, which have many single or double flowers, and the Pendula, with weeping stems and blossoms. Leaves are glossy and dark or medium green in color with a definite pointed tip.

Tuberous begonias need a rich but well-drained soil in a partially shaded garden location. They should receive direct sunlight only early in the morning. Because these are very tender tropical plants, they are most often grown in containers indoors, or if outdoors, in areas with warm winters and comfortable (not overly hot) summers. Excessive heat and humidity in summer will diminish and eventually wither these begonias. When the leaves begin to yellow in the autumn after flowering, reduce watering to induce the natural winter dormancy. In cold climates, this is the time that the tubers should be lifted and stored inside in a cool, dry location until buds reappear in the spring. They may be replanted in pots or outdoors once danger of frost has based and soil temperatures are warm.
