Cedrus libani - Cedar of Lebanon


Cedrus libani - Cedar of Lebanon



Location: Kew Gardens, London. C. libani is a statement of wealth, in 1638 the tree was introduced to Britain for its ornamental features, only the rich could afford it and the space for it to grow in.
The evergreen conifer can grow up to heights of 40m.
An easy way to distinguish it amongst other look a like cedars is buy it's fanning branches that appear in a horizontal fashion.


Long sinuous grey/brown ridged bark.


Male cones are round, greyish and up to 5 cm long, we know that this specimen is female because the cones are pinkish/brown when mature.


It's been quite dry for the past few days, we can tell this by observing how the ridges of the cones are slightly flared. Otherwise they would naturally close in wet conditions.


Needle like foliage is 3cm long and normally blue/green.
