- Cedar tree identification. Cedrus libani, commonly known as the Cedar of Lebanon is a species of cedar native to the mountains of the Eastern Mediterranean basin. It is an evergreen conifer that can reach 40 m in height. Cedrus libani is the national emblem of Lebanon and is widely used as an ornamental tree in parks and gardens in London.
Lebanon Cedar or Cedar of Lebanon C. libani
The Lebanon cedar is widely planted as an ornamental tree in parks and gardens.
It is unknown when the first cedar of Lebanon was planted in Britain, but it dates at least to 1664, when it is mentioned in Sylva, or A Discourse of Forest-Trees and the Propagation of Timber. In Britain, cedars of Lebanon are known for their use in London’s Highgate Cemetery. However, the plant is known among arborists for its tendency to drop branches without warning, and the use of wire bracing is common to reduce risks of falling branches.
C. libani has gained the Royal Horticultural Society’s Award of Garden Merit.
Made familiar, by name at least, from very early times by frequent references to it in the books of the Old Testament, it is rather strange that so hardy a tree was not one of the first of those introduced for ornament into Britain. It is true that local legends attaching to some old Cedars in this country credit them with having been planted in “the spacious times of great Elizabeth”-as the great Cedar at Whitton, Middlesex, blown down in 1779; but, on the other hand, we have the fact that no mention is made of the Cedar by John Evelyn in his “Sylva” (1664). This, it is true, is only negative evidence; but it is strong none the less, for it is not at all likely that so keen and pious an arboriculturist would have omitted mention of so noteworthy a tree had such been growing here when he wrote. There is reason to believe, however, that the still-existing Enfield Cedar was planted about the date of Evelyn’s publication by Dr. Uvedale, master of the Enfield Grammar School.
The researches of Sir J. D. Hooker, subsequent to his memorable expedition to Lebanon and Taurus in 1860, established the specific identity of the three Cedars known as the Mount Atlas Cedar, the Cedar of Lebanon, and the Deodar. Though the arboriculturist still treats them as distinct species, they are scientifically regarded as geographical forms of one species. For convenience we here adopt the arboriculturist’s view.
The Cedar varies greatly-no tree more so-in height and general outline, according to situation and environment, and though the stature of well-grown trees in this country may be correctly stated as from 50 to 80 feet, we are not without examples of 100 and 120 feet where the conditions have been specially favourable. There is one of 120 feet at Strathfieldsaye, and among the numerous fine Cedars at Goodwood there is the celebrated Great Cedar, 90 feet high, with a bole 25 feet in circumference, and a broad conical head whose base has a diameter of 130 feet. But the Cedar, as usually seen on lawns and in parks, has a low, rounded, or flattened top, the great spreading arms having grown more rapidly than the trunk. Thus grown, the huge bole has seldom any great length, throwing out these timber branches at from six to ten feet from the ground, and immediately afterwards the trunk is divided into several stems. From these the main branches take a curving direction, at first ascending, but the part furthest from the trunk becoming almost horizontal. It is chiefly at the extremity of the branches that the branchlets and leaves are produced.
The evergreen leaves last for three, four, or five years, and are of needle-shape, varying in length from a little less to a little more than an inch. They are produced in a similar manner to those of the Larch-in tufts that are arranged spirally round dwarf shoots, mostly on the upper side of the branchlets. The male flowers are to be found at the extremity of branchlets which, though six or seven years old, are very short, their development having been arrested. The solid, purple-brown cones are only three or four inches long, broad-topped, and with a diameter of about half the length; the scales thin and closely pressed together; they are at first greyish-green, tinged with pink. The development and maturity of these cones takes two or three seasons, and they remain on the tree for several years longer. The seeds are angular, with a wedge-shaped wing.
The trees do not produce cones until they are from twenty-five to thirty years old; but they may be a century old before producing either male or female flowers. londontreesurge...

Nothing more beautiful and majestic then the cedars of Lebanon, that’s why it’s on our flag🇱🇧
The lebanese cedars are so outstandingly handsome trees !!!
Very good video. We have three Cedar of Lebanon in our local Church grounds and they are very impressive trees.
Thanks for your comments, these impressive trees are in need of protection in their native territory and the mature trees we have here are important for the species as a whole. We love your channel of educational videos btw. Thanks again for your kind comments.
Great stuff guys!

Hi. How can you tell a C. libani from a C. deodara? Thanks.
Deodar cedar cones have slightly ridged scales, Cedar of Lebanon cones have smooth scales. The foliage and bark and the general shape of the tree also vary, there are some great comparison videos on our Cedrus playlist, hope this helps. ruclips.net/p/PL3hm4LtH_-drsqVbpve6yOv5vS9yd45FR
Thank you but I still don't feel confident to tell them apart. I'd need them both beside each other so I could really make out the differences. So similar to me.

Brothers and Sisters, God loves us so much that He sent His Son Jesus Christ for us to save us from our sins, and he bled and died on a cross for us to redeem us from death, and to gain life everlasting, for those who put their trust in him. And what's more, he has risen, and is willing to call you to repentance (correction) and as his witness, by his grace indeed. "For it is by grace you have been saved, through faith". Jesus loves you, God cares for you!
