Serbian spruce

It is a medium-sized evergreen tree growing to 20 m (66 ft) tall, exceptionally 33 m (110 ft), with a trunk diameter of up to 0.7 m (2 ft), and a conic crown; the crown is very narrow on high altitude trees, broader at lower altitudes. The shoots are buff-brown, and densely pubescent (hairy). The leaves are needle-like, 10–20 mm long, flattened in cross-section, dark green above, and with two glaucous blue-white stomatal stripes below. The cones are 4–7 cm (2–3 in) long, fusiform (spindle-shaped, broadest in the middle), dark purple (almost black) when young, maturing dark brown 5–7 months after pollination, with stiff scales. The tallest specimen in the wild currently known is 30.2 m tall; older claims of trees up to 50 m tall are now unverifiable. In cultivation, the tallest currently known is 33 m tall, in the Arboretum Mustila in Finland, with another not far behind at 31.5 m at Murthly Castle in Scotland.

Because of its limited range, it is not a major source of nutrition to wildlife, but does provide cover for birds and small mammals. Prior to the Pleistocene ice ages, it had a much larger range throughout most of Europe.

Outside its native range, Serbian spruce is of major importance as an ornamental tree in large gardens, valued in northern Europe and North America for its very attractive crown form and ability to grow on a wide range of soils, including alkaline, clay, acid and sandy soil, although it prefers moist, drained loam. The crown shape is heritable, with high altitude seed sources retaining the narrow crown in cultivation, and lower altitude sources their broader crown. It is also grown to a small extent in forestry for Christmas trees, timber and paper production, particularly in northern Europe, though its slow growth makes it less important than Sitka spruce or Norway spruce. In cultivation, it has produced hybrids with the closely related black spruce (named as P. × mariorika), and also with Sitka spruce.
