The perennials reach heights of 1,5 to 1,8 metres.
Begonia parviflora has dark-green, simple leaves that are alternate. The leaves are palmately lobed, lobate and petiolate.
Flowers and Fruits
Begonia parviflora produces cymes of white flowers from February to June.
The perennials produce loculicidal capsules.
The perennials prefer a sunny to half-shady situation on fresh to moist soil. The substrate should be sandy loam. They tolerate temperatures only above at least 1Â°C (USDA zone 10). Under glass use potting compost with added sand.
In summer the plants prefer moderate humidity, protection from direct sunlight. Tolerance of special soil conditions
- none: waterlogging
Suited for conservatories, as well as suited as indoor plant.
Maintenance and Propagation
- Repot as necessary in spring.
- For healthy growth apply a compound fertilizer monthly during growth.
- Water moderately in summer, give little water in winter.
- temperature in summer should be 19 to 23Â°C, in winter should be 19 to 23Â°C.
Pests and Diseases
White spots on flowers and leaves in combination with buds that do not open indicate an infestation with thrips. These insects can be controlled by improving ventilation and by watering regularly as well as by using an insecticide or biolocial pest control (predatory mites).
Waxy fibres and honeydew on leaves and shoots indicate an infestation with mealybugs. Apply insecticide or control biologically with predatory ladybirds.
Small dark-coloured beetles feeding on the plants are very likely vine weevils. Their larvae feed on seedling, cuttings, roots and tubers. Handpick and destroy pests and improve hygiene. Additionaly use insecticide or biological control (nematodes).
Honeydew, galls and distorted leaves are a sign for an infestation with aphids. Use an insecticide or control biologically , e.g. with parasitic wasps or predators such as Aphidoletes aphidimyza.
Rot on leaves, shoots, flowers or fruits indicated an infection with grey mould (botrytis). Remove and destroy affected plants. Apply fungizide. Improve ventilation and hygiene and avoid injuring the plants to prevent infections.
A powdery white coat on the plants indicates an infection with powdery mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.
Damaged roots, withering, decolouration and dieback of leaves and shoots may be caused by stagnant moisture, fungi or bacteria. Remove affected plants. Prevent by improving hygiene and drainage.
