Longleaf pine

Longleaf Pine (Pinus palustris)

Description

A tall evergreen tree, Pinus palustris, that grows in the southeastern United States. The longleaf pine, along with the slash pine, are the principal sources of turpentine. It is obtained from the sapwood of living trees. Longleaf pine trees are used for about half of the Kraft paper, Paperboard, and Book paper made in the United States. The hard, stiff, durable lumber was also used for ships, boxes, flooring, heavy construction, and millwork. Its highest production period for lumber was from 1850-1915.
