General Description

Big, dark velvety red, camellia-like blossoms on an upright, bushy plant with green foliage describes the slightly earlier-to-bloom-from-planting Primary Deep Red tuberous begonia. This compact plant belongs to the Tuberhybrida Group; this cultivar was developed from the slightly later flowering plants in the Nonstop Series. It grows from winter-dormant root tubers and has extravagant dark red flowers that are double (extra petal rows). 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.

Primary Deep Red tuberous begonia needs a rich, moist but well-drained soil in a partially shaded garden location. It should receive direct sunlight only early in the morning. Because a tropical plant, it's 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 this begonia. When a plant begins 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.
