(Kedros, ancient Greek name). Pinacese. Cedar. Trees grown for their persisting foliage and striking habit; they are also valuable timber trees.
Large evergreen trees, with quadrangular, stiff, fasciculate leaves: flowers monoecious, the staminate forming cylindrical catkins: cones ovate or ovate-oblong, thick, 3-5 in. long, with broad, closely i m b r i c a t e , bracts, attaining maturity in 2 or 3 years; seeds winged. - Three closely allied species in N. Africa, Asia Minor and Himalayas.
The cedars are large ornamental conifers, with wide-spreading branches, very distinct in habit from most other conifers. They are usually considered tender, but a hardy race of Cedrus Libani has been recently introduced by the Arnold Arboretum from the highest elevation where the species occurs in Asia Minor; the plants have stood all the winters since 1902 unprotected at the Arnold Arboretum and have proved perfectly hardy. It is very gratifying that one is now able to grow so far north the famous cedar of Lebanon which, aside from its beauty, is of peculiar interest for its historic and religious associations. The race of Cedrus Libani commonly cultivated is rather tender, more tender than C. atlantica which may be grown as far north as New York in sheltered positions, while C. Deodara can be grown safely only in California and southern states. The very durable and fragrant wood of all species is highly valued.
The cedars prefer well-drained, loamy soil, and will also grow in sandy clay, if there is no stagnant moisture. Propagated by seeds sown in spring; the varieties by veneer grafting, in late summer or in fall, on seedlings of C. atlantica; or, in warmer regions, on C.
Deodara; they grow also from cuttings, if the small shoots are selected which spring occasionally from the old wood. Plants of this genus are the true cedars; but trees of other genera are often called cedar. See Chamaecyparis, Junipenis, and Thuya; also Cedrela.
