Scots Pine, pino silvestre

Evergreen coniferous tree growing up to 35 m in height[ and 1 m trunk diameter when mature. The bark is thick, scaly dark grey-brown on the lower trunk, and thin, flaky and orange on the upper trunk and branches. The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of foliage.

On mature trees the leaves ('needles') are a glaucous blue-green, often darker green to dark yellow-green in winter, 2.5–5 cm long and 1–2 mm broad, produced in fascicles of two with a persistent grey 5–10 mm basal sheath. The seed cones are red at pollination, then pale brown, globose and 4–8 mm diameter in their first year, expanding to full size in their second year, pointed ovoid-conic, green, then grey-green to yellow-brown at maturity, 3-7.5 cm in length. The seeds are blackish, 3–5 mm long with a pale brown 12–20 mm wing; they are released when the cones open in spring 22–24 months after pollination. The pollen cones are yellow, occasionally pink, 8–12 mm long; pollen release is in mid to late spring.

The lifespan is normally 150–300 years, with the oldest recorded specimens (in Sweden and Norway) just over 700 years.
