The leaves are in fascicles of three, [6] needle-like, yellow-green, twisted, and 9–15 centimeters (3 + 1 ⁄ 2 –6 in) long. The cones are resin-sealed and irregularly shaped, [4] 8–16 cm (3 + 1 ⁄ 4 – 6 + 1 ⁄ 4 in) long and clustered in whorls of three to six on the branches. The scales end in a short stout prickle.
Tree height is the vertical distance between the base of the tree and the highest sprig at the top of the tree. The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or "where the acorn sprouted."
Pinus torreyana is a broad, open-crowned pine tree growing to 8–17 meters (26–56 ft) tall in the wild, with 25–30 centimeters (9.8–11.8 in) long leaves ('needles') in groups of five. The cones are stout and heavy, typically 8–15 cm (3.1–5.9 in) long and broad, and contain large, hard-shelled, but edible, pine nuts . [ 4 ]
Western white pine is a large tree, regularly growing to 30–50 metres (98–164 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, [ 5 ] with a deciduous sheath.
The pollen cones are circular, almost elliptical and are 10–20 millimeters in size. They are the same color as the bark, typically. Seed cones are spread throughout the tree. The mature seed cones (4–7 cm) are much larger than the pollen cones. [4] The P. virginiana prefers to grow in poor soils and dry loam or clay.
P. radiata is a coniferous evergreen tree growing to 15–30 m (50–100 ft) tall in the wild, but up to 60 m (200 ft) in cultivation in optimum conditions, with upward pointing branches and a rounded top. The leaves ("needles") are bright green, in clusters of three (two in var. binata), slender, 8–15 cm (3–6 in) long and with a blunt tip.

After maturity, which takes about two years, the cones will become brown in color. [13] These ancient trees have a gnarled and stunted appearance, especially those found at high altitudes, [8] and have reddish-brown bark with deep fissures. [14] As the tree ages, much of its vascular cambium layer may die. In very old specimens, often only a ...
