Cedrus deodara (deodar cedar, Himalayan cedar, or deodar/devdar/devadar/devadaru; Sanskrit देवदारु devadāru, Hindi: देवदार devadār, दारूक dāruk; Urdu: ديودار/ دیار deodār; Chinese: 雪松 xuě sōng) is a species of cedar native to the western Himalayas in eastern Afghanistan, northern Pakistan (especially in Khyber Pakhtunkhwa), north Republic of India (Jammu and Kashmir, Himachal Pradesh and Uttarakhand states), southwesternmost Tibet in (China) and western Nepal, occurring at Script error: No such module "convert". altitude. It is a large evergreen coniferous tree reaching Script error: No such module "convert". tall, exceptionally Script error: No such module "convert". with a trunk up to Script error: No such module "convert". in diameter. It has a conic crown with level branches and drooping branchlets.
The leaves are needle-like, mostly Script error: No such module "convert". long, occasionally up to Script error: No such module "convert". long, slender (Script error: No such module "convert". thick), borne singly on long shoots, and in dense clusters of 20–30 on short shoots; they vary from bright green to glaucous blue-green in colour. The female cones are barrel-shaped, Script error: No such module "convert". long and Script error: No such module "convert". broad, and disintegrate when mature (in 12 months) to release the winged seeds. The male cones are Script error: No such module "convert". long, and shed their pollen in autumn.
Cultural importance in the Indian subcontinent
Among Hindus, as the etymology of deodar suggests, it is worshiped as a divine tree. Deva, the first half of the Sanskrit term, means divine, deity, or deus. Dāru, the second part, is cognate with (related to) the words durum, druid, tree, and true.

Forests full of Deodar or Devadāru trees were the favorite living place of ancient Indian sages and their families who were devoted to the Hindu god Shiva. To please Lord Shiva, the sages used to perform very difficult tapasya (meditation) practices in deodar forests. Also the ancient Hindu epics and Shaivite texts regularly mention Darukavana, meaning a forest of deodars, as a sacred place.
Cultivation and uses
It is widely grown as an ornamental tree, often planted in parks and large gardens for its drooping foliage. General cultivation is limited to areas with mild winters, with trees frequently killed by temperatures below about Script error: No such module "convert"., limiting it to USDA zone 7 and warmer for reliable growth. It can succeed in rather cool-summer climates, as in Stateline, Nevada and Ushuaia, Argentina.
The most cold-tolerant trees originate in the northwest of the species' range in Kashmir and Paktia Province, Afghanistan. Selected cultivars from this region are hardy to USDA zone 7 or even zone 6, tolerating temperatures down to about Script error: No such module "convert".. Named cultivars from this region include 'Eisregen', 'Eiswinter', 'Karl Fuchs', 'Kashmir', 'Polar Winter', and 'Shalimar'. Of these, 'Eisregen', 'Eiswinter', 'Karl Fuchs', and 'Polar Winter' were selected in Germany from seed collected in Paktia; 'Kashmir' was a selection of the nursery trade, whereas 'Shalimar' originated from seeds collected in 1964 from Shalimar Gardens, India (in the Kashmir region) and propagated at the Arnold Arboretum.
Deodar is in great demand as building material because of its durability, rot-resistant character and fine, close grain, which is capable of taking a high polish. Its historical use to construct religious temples and in landscaping around temples is well recorded. Its rot-resistant character also makes it an ideal wood for constructing the well-known houseboats of Srinagar, Kashmir. In Pakistan and India, during the British colonial period, deodar wood was used extensively for construction of barracks, public buildings, bridges, canals and railway cars. Despite its durability, it is not a strong timber, and its brittle nature makes it unsuitable for delicate work where strength is required, such as chair-making.
The inner wood is aromatic and used to make incense. Inner wood is distilled into essential oil. As insects avoid this tree, the essential oil is used as insect repellent on the feet of horses, cattle and camels. It also has anti-fungal properties and has some potential for control of fungal deterioration of spices during storage.  The outer bark and stem are astringent.
Due to its anti fungal and insect repellent properties, rooms made of Deodar (Cedrus deodara) wood are used to store meat and food grains like oats and wheat in Shimla, Kullu and Kinnaur district of Himachal Pradesh. In Himachal people suffering from asthma or other respiratory problems are advised to sit under a Deodar tree early in the morning.
Cedar oil is often used for its aromatic properties, especially in aromatherapy. It has a characteristic woody odour which may change somewhat in the course of drying out. The crude oils are often yellowish or darker in colour. Its applications cover soap perfumes, household sprays, floor polishes and insecticides and is also used in microscope work as a clearing oil.
The bark of Cedrus deodara contains large amounts of taxifolin. The wood contains cedeodarin (6-methyltaxifolin), dihydromyricetin (ampelopsin), cedrin (6-methyldihydromyricetin), cedrinoside and deodarin (3′,4′,5,6-tetrahydroxy-8-methyl dihydroflavonol). The main components of the needle essential oil include α-terpineol (30.2%), linalool (24.47%), limonene (17.01%), anethole (14.57%), caryophyllene (3.14%) and eugenol (2.14%). The deodar cedar also contains lignans and the phenolic sesquiterpene himasecolone together with isopimaric acid. Other compounds have been identified as (−)-matairesinol, (−)-nortrachelogenin and a dibenzylbutyrolactollignan (4,4',9-trihydroxy-3,3'-dimethoxy-9,9'-epoxylignan).
