Pseudotsuga menziesii - Douglas Fir

Introduced from North America by the great plant hunter David Douglas in the 1830’s, the Douglas Fir is the second tallest tree in the world. In the wild it can reach 100m, but its more usual height in cultivation is nearer 50m. It is an impressive, handsome tree with richly scented foliage and is used equally in commercial plantations and as a specimen tree in large parks and gardens.
