Cinnamomum
Family: Lauraceae
Common Name: Camphor Tree
These aromatic trees and shrubs have considerable commercial value: C. camphora yields camphor oil and the bark of C. zeylanicum is used to make cinnamon, commonly used in curries and cakes. Mostly shapely evergreens, they have dense, leathery foliage, sprays of small bisexual or unisexual flowers, and blue-black berries.
Species
C. camphora, camphor tree, originating in tropical Asia, is the most widely grown species. It has 12 cm (5 in) long leaves, whitish on the undersides, and yellow flowers. It can grow as tall as 30 m (100 ft). The fine timber is used in cabinetwork as it carves well.
C. zeylanicum, cinnamon tree, a native of India and Sri Lanka, grows to 9 m (30 ft), with yellowish white flowers. The well-known spice is derived from the ground bark of the tree and is used in both sweet and savory dishes.
Cultivation
In frost-prone climates, grow in an intermediate greenhouse or conservatory as foliage plants. Use soil-based potting compost. Outdoors, in the right climate, these trees are easy to grow. Propagate from seed sown in spring in warmth or from semi-ripe cuttings in summer.
