Picea orientalis

The Caucasian Spruce can also be found in Northern Iran, though its numbers have decreased due to deforestation.

The leaves are needle-like, the shortest of any spruce, 6–8 mm long, rhombic in cross-section, dark green with inconspicuous stomatal lines.

It is a popular ornamental tree in large gardens, valued in northern Europe and the USA for its attractive foliage and ability to grow on a wide range of soils.

It is also grown to a small extent in forestry for Christmas trees, timber and paper production, though its slower growth compared to Norway spruce reduces its importance outside of its native range.

P. orientalis[3] and the cultivars 'Aurea' [4] and ‘Skylands’[5] have gained the Royal Horticultural Society's Award of Garden Merit.
