In old-growth pine, the heartwood of the bole is often saturated in the same way. When boards are cut from the fat lighter wood, they are very heavy and will not rot, but buildings constructed of them are quite flammable and make extremely hot fires. The seeds of the longleaf pine are edible raw or roasted. [29]
Pinus flexilis, the limber pine, is a species of pine tree in the family Pinaceae that occurs in the mountains of the Western United States, Mexico, and Canada. It is also called Rocky Mountain white pine. A limber pine in Eagle Cap Wilderness, Oregon, has been documented as over 2,000 years old, and another one was confirmed at 1,140 years old.
Pine was also a favorite tree of loggers, since pine logs can still be processed in a lumber mill a year or more after being cut down. In contrast, most hardwood trees such as cherry, maple, oak, and ash must be cut into 1" thick boards immediately after felling, or else large cracks will develop in the trunk which can render the wood worthless.
Pinus sabiniana trees typically grow to 11–14 metres (36–45 ft), but can reach 32 m (105 ft). The pine needles are in fascicles (bundles) of three, distinctively pale gray-green, sparse and drooping, and grow to 20–30 centimetres (8–12 in) in length.

The bundle-sheath is persistent. The buds are blunt pointed, up to 15 mm long, reddish-brown, and resinous.

The PTI preservative imparts very little color to the wood. Producers generally add a color agent or a trace amount of copper solution so as to identify the wood as pressure treated and to better match the color of other pressure treated wood products. The PTI wood products are very well adapted for paint and stain applications with no bleed ...
