- Description
-
Longleaf Pine is an evergreen gymnosperm tree that may grow 60 to 120 feet tall. The tree has 8- to 18-inch slender and feathery needles in clusters of 3. The needle clusters tend to be tufted at the end of branches. This tree produces numerous, dense, long-needled fascicles. As the tree ages, the bark thickens forming irregular, flaky plates. In spring, long, yellow-red, male and oval, purple, female flowers mature. The tree produces both a purple-blue male cone and a dark purple female cone.
The Longleaf pine does best in full sun. It grows well in well-drained sandy or clay soils in full sun. It is a difficult tree to transplant and has a slow growth rate. This tree is susceptible to ice and storm damage, and is also not tolerant of lightning, high winds or drought. It is difficult to transplant. It grows in "grass-like" stage for the first 5 years, staying at a very short size. Seeds need to be exposed to fire before germination can occur.
It has historically been used for naval purposes, specifically for pitch, tar, resin, and turpentine, and is still used for lumber today. The wood is known for its heaviness, strength, and durability. This plant can be utilized as a specimen plant. Needles can be used as pine mulch, but fallen shoots with needles can be a litter problem.
The largest cone in the Eastern US is 6-10 in. red-brown ovoid to conical shape with umbo armed with curved prickle.
