Scot this tree is the national tree of Lebanon and is featured on that country's flag. A rarely seen but hardy tree in the most southern areas of Ontario. It is quite unique in the landscape for its stark, refined form. Well worth a try and valuable for the purpose of winter interest.

Description and Growing Information
Flowering Period
General Description
Large stately evergreen with a massive trunk when mature, along with wide-sweeping, horizontal branches which originate on the lower trunk. Dark green needles and cones are held upright above the foliage.
It is not suited to street plantings but makes an exceptional specimen tree. It is widely used as an ornamental in southern climates and produces a very statuesque form with age.
Is widely cultivated as an ornamental species in southern climates. Requires about 1000 mm of rain a year. They form open forests with a low undergrowth of grasses in their native habitat.
Irregular and tightly pyramidal in youth; as it ages, massive horizontal spreading of the limbs takes place.
ID Characteristic
Stately specimen tree. Pyramidal shape when young. Flat-topped, slightly loose, and spreading tree with strong horizontal branching when mature. This is the most cold-hardy of the Cedrus genus.
No pests or diseases of consequence.
Full sun, intolerant of drought. Prefers moist, well-drained fertile soil, but will survive poor soils.

Notable Specimens
Niagara Parks Botanical Gardens, Niagara Falls, Ontario. Westonbirt, The National Arboretum, Tetbury, Gloucestershire, England. Goodwood House, Chichester, England where 45 plants remain from an original 1760's planting. Some 350 young plants from wild collected origins will be planted over 30 sites in England in the next few years (2015) including Edenhall, Penrith; Old Rectory, Wantage; and Goodwood House, Chichester.
Propagate from seed and sow as soon as it ripens. It is difficult to propagate from cuttings, and it does not like to be transplanted.
