Propagation
Surface sow fresh seeds during spring in a well-drained media, and maintain a temperature of 16º to 18º C. (61º to 64º F). Prick out and pot up when they are large enough to handle.
Take basal and stem cuttings during early summer.
Botanic information
Leaf: The large glossy dark green ovate leaves may appear sparsely on the plant and the margin is serrate to slightly lobed. They have a fleshy texture and the upper surface of the leaf has prominent venation. The leaves tend to billow out from the petiole forming a cordate base.
Flower: The cyathiform flowers are arranged in a cluster with 2-females and 1-male flower. These may be in single or double and are avalable in all colours except blue. They may be very large and heavy tending to be pendant and may require staking. The flowers appear during summer.
Fruit: The capsule is small and winged. The seed is very fine powder-like, not normally seen and the plant is usually reproduced vegetatively in order to maintain true to type.
Culture
Begoniaspecies require a temperature that is not less than 12.7ºC (55ºF) and placed in bright indirect light.
The soil should be allowed to dry on the surface before re-watering. Never allow the soil to become wet permanently as this will cause rot and when watering avoid wetting the leaves, the pot may be emersed in water and then allowed to drain. They prefer a humid environment and this may be achieved by misting the surrounding air but again avoid misting the leaves.
During the growing period liquid fertiliser every 10 to 14 days prior to flowering to promote growth. During winter reduce watering and in many cases the plant will shed leaves during this period.
Re-pot the plants during spring when they are pot bound or when the leaves lose colour.
