Flower: clusters of trumpets, 5cm (about 2 inches) violet/lavender inside with a deep coloured throat, white with fine hairs outside. The plant can start growing flowers as early as 18 months from seed. For this to occur, there must be sufficient watering and adequate room for the roots to grow; it can take up to five years for the first signs of flowering to become visible.
Fruit: “Woodrose”; globular berry, 1 to 2cm diameter, with rosette of “wooden” petals. Often sold for dried flower arrangements/pot-pourri.

Foliage: 15 to 40cm long cordate (heart-shaped) prominently nerved leaves, felted (tomentose) beneath with minute silky hairs.

Seeds :
The seeds are found in the pods of dried flowers. These cannot be harvested until the pods are completely dried. There are 3 to 5 seeds, commonly 4, per flower.

Roots

Some people place approximately 1 to 2 inches (2 to 4 cm) in rich potting soil with a good drainage system. It is very important during the first stages of growth to keep the soil moist, though well drained, as saturation will cause root rot and possibly rot. It is important to keep the mix well aerated.

The massive root system of this plant can cause the plant to become rootbound within the first year or so. For example, a 5-year-old plant in a 15-gallon pot (after only six months) will begin to show signs of becoming rootbound. It is suggested to use a 55-gallon drum or a feeding trough (commonly used for livestock and horses).

Cultivation:

Very easy !

Just soak the seeds in water overnight, then keep them on a moist paper towel until the roots start to poke out.

When you can see a little white root starting to push out from one end of a seed sow the seed into a water retaining but free draining growing mix – about an inch (2 cm) or slightly more below the surface with the little root pointing upwards !

Within a few days the first 2 leaves will pull themselves out of the ground.

Chemical constituents — The plant contains tannin and amber-colored resin, soluble in ether, benzole; partly soluble in alkalis; and fatty oil.103

The seeds have shown the presence of alkaloids, viz., chanoclavine, ergine, ergonovine, and isoergine by various workers.10

Botanical Name: Cedrus deodara
Family :Pinaceae
Kingdom: Plantae
Division: Pinophyta
Class: Pinopsida
Order: Pinales
Genus: Cedrus
Species: C. deodara

Synonym(s): Cedrus libani Barrel, Pinus deodara Rxb.

Common Name: Deodar Cedar, Himalayan Cedar, or Deodar; Hindi, Sanskrit: devadaru; Chinese: xue song.

The specific epithet and English vernacular name derive from the Sanskrit devad?ru, “wood of the gods”, a compound of deva (god) and daru (wood).

Parts used: Heartwood, bark, leaves and oil.

Habitat: Native to the western Himalayas in eastern Afghanistan, northern Pakistan, north-central India (Himachal Pradesh, Uttarakhand states,Kashmir, southwesternmost Tibet and western Nepal, occurring at 1500-3200 m altitude.

Cultural importance in the Indian subcontinent:
It is worshipped as a divine tree in the Indian subcontinent, particularly in Kashmir and Punjab villages, as the name deodar, a Sanskrit word, (Sanskrit: devdar), which means, “divine wood”. The first half of the word deva means the words divine, deity, deus, and Zeus and the second part connotes durum, druid, tree, and true. Several Hindu legends refer to this tree.

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.
It is the national tree of Pakistan.

Description:
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.Dioecious trees are very rare.

CLICK & SEE

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.

Cultivation and uses
It is widely grown as an ornamental tree, much 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 ?25 °C, limiting it to hardiness zones 8 and warmer for reliable growth. It is commonly grown in western Europe (north to Scotland), in the Mediterranean region, around the Black Sea, in southern and central China, on the west coast of North America as far north as Vancouver, British Columbia, and in the southeastern United States from Texas to Virginia.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.

Use in Construction material:
Deodar is in great demand as building material because of its durability, rot-resistant character and fine close grain, which is capable of taking high polish. It’s historical use to construct religious temples and as landscape around temples is well recorded. In India, during the British colonial period, deodar wood was used extensively for construction of barracks, public buildings, bridges, canals and railway cars.

Hydrocarbons
The petroleum ether extract of the bark oil yields saturated, straight chain and branched chain hydrocarbons (CI4-C2O)’

Flavonoids
Stem bark contains deodarin (3′,4′,5,7-tetrahydroxy-8-C-methyl dihydroflavonol), taxifolin and quercetin.
