Description
It is a large coniferous evergreen tree growing to 30–40 metres (98–131 ft) tall (exceptionally to 57 m),[2][3] and with a trunk diameter of up to 1.5 m (rarely up to 2.3 m).[3]
The shoots are buff-brown and moderately pubescent (hairy). The leaves are needle-like, the shortest of any spruce, 6–8 mm long, rhombic in cross-section, glossy dark green with inconspicuous stomatal lines. The cones are slender cylindric-conic, 5–9 cm long and 1.5 cm broad, green or red to purple when young, maturing dark brown 5–7 months after pollination, and have stiff, smoothly rounded scales.[2][4]
Cultivation
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[5] and the cultivars 'Aurea' [6] and 'Skylands'[7] have gained the Royal Horticultural Society's Award of Garden Merit.[8] A frequently seen ornamental cultivar is Picea orientalis 'Aureospicata', which has gold-coloured young foliage in the spring.
