Begonia Rex Hybrids


Begonia rex originated in Assam. The varieties available are all hybrids of this plant with one of the countless other Asiatic begonias and may be found on the market under the collective name of Begonia Rex hybrids. Their leaves are up to 30cm (12in) in length and their great weight can cause the plant to topple over. Re-pot into a large or heavy pot as soon as you obtain the plant. Never plant it more deeply than it was before, because that may cause rotting. The leaves are often brilliantly marked and have a beautiful sheen. The patterns are mainly built up of the colours pink, carmine, silver, green and red-brown. The plants are imported in mixed batches so that that you can choose the colour combination that you like from those on offer. If a leaf breaks off it can be used as a cutting. Put the leaf on damp compost and cut through the veins in a few places with a sharp knife. Cover with plastic and put in a warm spot, out of direct sunlight. After a few weeks new plants will have developed where the cuts were made and you can pot them on individually.

Begonia Bowerae


This Mexican begonia is in fact called Begonia bowerae but is usually offered under the incorrect name ‘boweri’. White flowers flushed with pink adorn the plant; however, that is not the reason why it is sold. Its decorative value lies mainly in its light green leaves which have black and brown spots and are edged with white hairs. Some cultivars have been developed from the species which is itself rarely on offer. You can usually find ‘Tiger‘ which has olive-green leaves with light green spots. The undersides of the leaves and the brittle, juicy stems, are wine-red. Give it a light but not too sunny location in a heated room. Water regularly with hand-warm water, so that the compost stays always moist but never soaking-wet. Do not spray because this may encourage mildew and give as much fresh air as possible, avoiding draughts or cold air, and a temperature of preferably at least 15°C (59°F). Pot on every half year and regularly give liquid feed. Always leave the plant in the same position in relation to the light.
