General Description

Big, camellia-like blossoms on an upright, bushy plant with mainly green foliage describes the slightly earlier-to-bloom-from-planting Primary Series of tuberous begonia. These compact plants belong to the Tuberhybrida Group; this collection was developed from the slightly later flowering plants in the Nonstop Series. Plants arise from winter-dormant root tubers and flowers come in all colors except blue. These extravagant flowers are often double. They are produced in early summer to mid-autumn, 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. Leaves are fleshy, jagged and pointed, glossy and dark green, sometimes with bronze tones and undersides.

Primary Series 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 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 plants 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 passed and soil temperatures are warm.
