This species has the same uses as the closely related C. sanguinea. These uses are listed below: The seed contains 45% of a non-drying oil, it is used in soap making and lighting. A non-drying oil is also obtained from the pericarp, it is used for lighting. The pericarp contains 19 - 35% oil. A greenish-blue dye is obtained from the fruit. The young stems are very flexible and are used in basketry. Wood - tough, hard. Used for small items such as tool handles, turnery etc. A good quality charcoal is obtained from the wood, the wood also makes an excellent fuel.

Basketry: Plant used in making baskets and other items such as chairs. Includes plants that are only used as an ornamental addition.

Charcoal: Used for fuel, drawing, deodorant, filter, fertilizer etc.

Dye: Plants that provide dyes.

Fuel: Usually wood, plant materials that have been mentioned as being a good fuel.

Hedge: Plants that can be grown as hedges.

Oil: Vegetable oils have many uses, as lubricants, lighting, soap and paint making, waterproofing etc. This does not include the edible oils unless they are also mentioned as having other uses.

How it is grown

An easily grown plant, it succeeds in any soil of good or moderate fertility, ranging from acid to shallow chalk. Grows well in heavy clay soils. Succeeds in full sun or light shade. This species is closely related to C. sanguinea. Plants in this genus are notably resistant to honey fungus.

Propagating it: Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed. The seed must be separated from the fruit flesh since this contains germination inhibitors. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year. Scarification may also help as may a period of warm stratification before the cold stratification. Germination, especially of stored seed, can be very slow, taking 18 months or more. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage. Layering of new growth in June/July. Takes 9 months.
