Cedrus deodara (Deodar Cedar, Himalayan Cedar, or Deodar; Hindi, Sanskrit: देवदार devadāru; Chinese: 雪松 xue song) is a species of cedar native to the western Himalaya in eastern Afghanistan, northern Pakistan, north-central India (Himachal Pradesh, Uttarakhand states), Kashmir, southwesternmost Tibet and western Nepal, occurring at 1500-3200 m altitude. It is a large evergreen coniferous tree reaching 40-50 m tall, exceptionally 60 m, with a trunk up to 3 m diameter. It has a conic crown with level branches and drooping branchlets.
The leaves are needle-like, mostly 2.5-5 cm long, occasionally up to 7 cm long, slender (1 mm 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, 7-13 cm long and 5-9 cm broad, and disintegrate when mature (in 12 months) to release the winged seeds. The male cones are 4-6 cm long, and shed their pollen in autumn.

That means “In the stands of Lodhra trees, Padmaka trees and in the woods of Devadaru, or Deodar trees, Ravana is to be searched there and there, together with Seetha. [4-43-13]”
Forests full of Devadaru trees were the favorite abode or living place of ancient Indian sages and their families who were devoted to Hindu god Shiva for whom they performed very difficult tapasya (meditation) to please him.
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 zone 7 or even zone 6, tolerating temperatures down to about −30 °C. 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.
