Grown for their foliage, fruits and flowers or ornamental, often prickly stems. Deciduous species may be grown for their winter stems Suitable for coastal conditions.
They are fully to half hardy and will prefer full sun, and other deciduous species need sun or semi-shade, with evergreens and semi-evergreens tolerating sun or shade as well. They all require fertile, well drained soil. Cut old stems of R.biflorus, R.cockburnianus and R.thibetanus to ground after fruiting.
Propagate by seed or cuttings (semi-ripe for evergreens, softwood or hardwood for deciduous species) in summer or winter. Alternatively, R.odoratus may be increased by division and R.'Benenden' and R.ulmifolius 'Bellidiflorus' by layering in spring. You can also propagate by root division in winter.
