Among the distinctive qualities of the dragon wing red begonia, which grows in a dense mound 15 to 18 inches in height and width, are its shiny, 5-inch leaves, which resemble angel-wings, and its large, drooping red blossoms. The dragon wing red begonia does well in shade, blooms from late spring to frost and tolerates hot and humid climates, with few insect or disease problems. It requires moderately moist soil with good drainage, but can handle short dry periods.
The dragon wing red begonia draws bees, butterflies and birds to the garden and is appropriate for flower beds and also containers due to the arch and droop of its stems. The dragon wing begonia is a sterile hybrid, which accounts for its continuous blooming. While it is difficult to grow this begonia from seed because of its very small seeds, starting seeds indoors six to eight weeks before the last frost is possible. Overwintering dragon wing begonias in containers is an option that also provides cuttings. To overwinter this begonia, cut it back, place it in a cool indoor location and reduce watering, returning the container to the garden after the last frost.
While the dragon wing red begonia is of the herbaceous perennial type, gardeners typically grow it as an annual. It is best grown in growing zones 10 to 11 and can handle temperatures down to 40 degrees Fahrenheit.
