Cultivation

Plants can be grown from seed. The seed should be washed before planting. Stored seed needs 2-3 months of cold treatment before they will grow. Seeds germinate in 6 weeks at 20°C. Seedlings are planted out after a year. Semi-ripe cuttings can be used. Stems can be pegged down into the soil and take 12 months to form roots.
