Norway spruce is a large, fast-growing evergreen coniferous tree growing 35–55 m (115–180 ft) tall and with a trunk diameter of 1 to 1.5 m (39 to 59 in). It can grow fast when young, up to 1 m (3 ft) per year for the first 25 years under good conditions, but becomes slower once over 20 m (65 ft) tall. The shoots are orange-brown and glabrous (hairless). The leaves are needle-like with blunt tips, 12–24 mm (15󉪰–15󉪠 in) long, quadrangular in cross-section (not flattened), and dark green on all four sides with inconspicuous stomatal lines. The seed cones are 9–17 cm (3 1𔊪–6 3𔊬 in) long (the longest of any spruce), and have bluntly to sharply triangular-pointed scale tips. They are green or reddish, maturing brown 5–7 months after pollination. The seeds are black, 4–5 mm (5󉪰–3󉪠 in) long, with a pale brown 15-millimetre (5𔊰-inch) wing. The tallest measured Norway spruce is 62.26 m (204 ft) tall and grows near Ribnica na Pohorju, Slovenia. Learn more about Norway Spruce
