Cedrus deodara, the deodar cedar, Himalayan cedar, or deodar,{{GRIN | access-date = 24 May 2021}} is a species of cedar native to the Himalayas.

Description

It is a large evergreen coniferous tree reaching {{convert|40|-|50|m|0|abbr=off}} tall, exceptionally {{convert|60|m|0|abbr=on}} with a trunk up to {{convert|3|m|0|abbr=on}} in diameter. It has a conic crown with level branches and drooping branchlets.{{cite book |first=Farjon |last=Aljos |year=1990 |title=Pinaceae: drawings and descriptions of the genera Abies, Cedrus, Pseudolarix, Keteleeria, Nothotsuga, Tsuga, Cathaya, Pseudotsuga, Larix and Picea |location=Koenigstein |publisher=Koeltz Scientific Books |isbn=978-3-87429-298-6}}{{page needed|date=September 2013}}

The leaves are needle-like, mostly {{convert|2.5|–|5|cm|abbr=off|frac=4}} long, occasionally up to {{convert|7|cm|abbr=on|frac=2}} long, slender ({{convert|1|mm|abbr=out|disp=or|frac=32}} 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, {{convert|7|–|13|cm|abbr=on|frac=4}} long and {{convert|5|–|9|cm|abbr=on|frac=4}} broad, and disintegrate when mature (in 12 months) to release the winged seeds. The male cones are {{convert|4|–|6|cm|abbr=on|frac=4}} long, and shed their pollen in autumn.

Etymology

The botanical name, which is also the English common name, is derived from the Sanskrit term devadāru, which means "wood of the gods", a compound of deva "god" and dāru "wood and tree".{{Cite journal |last1=Shinde |first1=U.

Cultivation

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 {{convert|-25|C|F}}, limiting it to USDA zone 7 and warmer for reliable growth.{{cite book |last=Ødum |first=S. |year=1985 |title=Report on frost damage to trees in Denmark after the severe 1981/82 and 1984/85 winters |publisher=Hørsholm Arboretum |location=Denmark}}{{page needed|date=September 2013}} It can succeed in rather cool-summer climates, as in Ushuaia, Argentina.{{cite web |url=http://treesneartheirlimits.blogspot.ca/ |title = Trees Near Their Limits}}

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 {{convert|-30|C|F}}. Named cultivars from this region include 'Eisregen', 'Eiswinter', 'Karl Fuchs', 'Kashmir', 'Polar Winter', and 'Shalimar'.{{cite book |first1=Welch|last1=Humphrey James |editor1-last=Haddows |editor1-first=Gordon |year=1993 |title=The World Checklist of Conifers |location=Bromyard |publisher=Landsman's Bookshop |isbn=978-0-900513-09-1}}{{cite book |first=Krüssmann |last=Gerd |year=1983 |title=Handbuch der Nadelgehölze |edition=2nd |location=Berlin |publisher=Parey |isbn=978-3-489-62622-0 |language=de}}{{page needed|date=September 2013}} 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, Kashmir and propagated at the Arnold Arboretum.

Uses

=Construction material=

File:Cedrus deodara00.jpg

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.{{Citation needed|date=April 2017}}

= Herbal Ayurveda =

C. deodara is used in Ayurvedic medicine.

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 antifungal properties and has some potential for control of fungal deterioration of spices during storage.{{citation needed|date=December 2017}} The outer bark and stem are astringent.{{cite book |chapter-url=http://www.fao.org/docrep/V5350e/V5350e12.htm |chapter=Cedarwood Oils |title=Flavours and fragances of plant origin |year=1995 |publisher=Food and Agriculture Organization of the United Nations |isbn=92-5-103648-9 |access-date=2008-08-26 |archive-date=2011-06-18 |archive-url=https://web.archive.org/web/20110618030456/http://www.fao.org/docrep/v5350e/v5350e12.htm |url-status=dead }}

Because of its antifungal and insect repellent properties, rooms made of deodar cedar wood are used to store meat and food grains like oats and wheat in Shimla, Kullu, and Kinnaur district of Himachal Pradesh.

Cedar oil is often used for its aromatic properties, especially in aromatherapy. It has a characteristic woody odor which may change somewhat in the course of drying out. The crude oils are often yellowish or darker in color. Its applications include soap perfumes, household sprays, floor polishes, and insecticides, and is also used in microscope work as a clearing oil.

The gum of the tree is used to make rope incense in Nepal and Tibet.{{Cite news |last=Andrews |first=Arden Fanning |date=2021-09-10 |title=An Incense for Every Occasion |language=en-US |work=The New York Times |url=https://www.nytimes.com/2021/09/10/t-magazine/incense-guide.html |access-date=2022-12-14 |issn=0362-4331}}

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.{{cite web |url=http://jcmcgowan.blogspot.com/2008/03/blog-post.html |first=Chris |last=McGowan |date=March 5, 2008 |title=The Deodar Tree: the Himalayan 'Tree of God'}}{{self-published inline|date=September 2013}} Several Hindu legends refer to this tree.
