Description
The Longleaf Pine is a magnificent and iconic conifer of the American Southeast, famous for its exceptionally long, dark green needles and large cones. Growing as a tall, straight tree reaching heights of 80 to 100 feet, it features thick, scaly, reddish-brown bark that provides remarkable fire resistance. In its youth, the tree spends several years in a unique 'grass stage' where it resembles a clump of grass rather than a tree, developing a massive taproot before sending up a rapid vertical shoot. The needles are soft, flexible, and hang in dramatic tufts at the ends of stout branches, creating an open, park-like canopy that allows ample sunlight to reach the forest floor.
Habitat
Coastal plain flatwoods, sandy soils, and rolling hills with frequent low-intensity fire regimes, requiring full sun exposure and well-draining acidic soils
Native Range
Native to the southeastern United States, stretching from southeastern Virginia down through Florida and west to eastern Texas
