[13] [14] The longleaf pine (Pinus palustris) is characterized as having bushy clusters of 10 inches (25 cm) long needles and large 6 to 12 inches (15 to 30 cm) long pine cones. These pines are capable of growing 80 to 100 feet (24 to 30 m) tall with a diameter of 2.5 feet (80 cm) across, only in well suited soil.
A seed cone takes two years to fully ripen. Each scale of the cone is tipped with a thin, brittle pickle 4–10 millimeters long. They fall from the tree soon after releasing their seeds. [5] Pinus aristata has seeds that are gray-brown to nearly black in color with darker spots and 5–6 mm long. The seed has an attached papery wing 10–13 mm ...

Longleaf pine takes 100 to 150 years to become full size and may live to be 500 years old. When young, they grow a long taproot, which usually is 2–3 metres (6 + 1 ⁄ 2 –10 feet) long; by maturity, they have a wide spreading lateral root
The name Pinus coulteri comes from Latin for pine, and coulteri comes from its discoverer Thomas Coulter (1793–1843), an Irish botanist and physician. [9] Pinus coulteri was discovered by Dr. Coulter on the mountains of Santa Lucia, near the Mission of San Antonio, in latitude 36°, within sight of the sea and at an elevation of from 3000 to 4000 feet above its level.
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. Cones can sometimes be found attached to the trunk and larger branches. [4]
