Species distribution: Afghanistan, India, Nepal, Pakistan Exotic range: Argentina, Canada, China, France, Germany, Italy, Spain & Indian Sub-Continent. One of three cedars commonly found in Britain, this native of the Himalaya was introduced here in 1831. Its strong fragrant wood is used for timber in Pakistan and India but following a failed experiment to grow it commercially it is now grown purely for its ornamental value in the British Isles.

Natural Regeneration
Natural Regeneration Seed years: Every third year is a good seed year with abundant cone bearing trees. Seed dispersed in Oct-Nov remains on the ground throughout the winter, under the snow and germinates in the spring during March-April germination takes earlier in the warmer than the cooler aspects.

Economic Importance:

1. A fairly wind-tolerant tree, it can be used in shelter-belt plantings.

2. It is widely grown as an ornamental tree, often planted in parks and large gardens for its drooping foliage.

3. The bark of cedar wood proves to be a good remedy in remittent and intermittent fevers, diarrhea and dysentery. The powder is used in the treatment of ulcers.

4. The inner wood of the plant is aromatic and is thus, used to make incense. The inner wood is also distilled to make essential oils.

5. The essential oil obtained from this plant is used as insect repellant on the feet of horses, cattle and camels, as insects avoid venturing close to it.
