Pinus monticola

Foliage and cones
Western white pine (Pinus monticola) is a large tree, regularly growing to 30–50 metres (98–164 ft) and exceptionally up to 70 metres (230 ft) tall. It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. The needles are finely serrated, and 5–13 cm (2–5 in) long. The cones are long and slender, 12–32 cm (4 ⁄4–12 ⁄2 in) long and 3–4 cm (1 ⁄4–1 ⁄2 in) broad (closed), opening to 5–8 cm (2–3 ⁄4 in) broad; the scales are thin and flexible. The seeds are small, 4–7 mm (⁄16–⁄4 in) long, and have a long slender wing 15–22 mm (⁄16–⁄8 in) long.
It is related to the Eastern white pine (Pinus strobus), differing from it in having larger cones, slightly longer-lasting leaves (2–3 years, rather than 1.5–2 years) with more prominent stomatal bands, and a somewhat denser and narrower habit. The branches are borne in regular whorls, produced at the rate of one a year; this is pronounced in narrow, stand-grown trees, while open specimens may have a more rounded form with wide-reaching limbs. It is widely grown as an ornamental tree, but has been heavily logged throughout much of its range in the past.

Water moderately, allowing the top 3cm to dry out between watering.
