- Description
-
The longleaf pine is an evergreen, gymnosperm tree in the Pinaceae (pine) family that may grow 60 to 120 feet tall with short, stout, spare branches forming an open, irregular crown. It is native to the southern United States and ranges from Virginia west to Texas and south to Florida. The tree produces both a purple-blue male cone and a dark purple female cone. The cones are the largest of any pine in eastern North America.
The longleaf pine does best in full sun and prefers well-drained, acidic, sandy or clay soils. This tree is difficult to transplant because it rapidly produces a deep taproot. It grows in a "grass-like" stage for the first five years, staying very short in height but allowing the stem to grow in thickness. 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. It is home to the endangered red-cockaded woodpecker and also provides food and winter cover for other wildlife.
This tree can be utilized as a specimen plant or in a mass planting to create a naturalized area. Needles can be used as pine mulch, but fallen shoots with needles can be a litter problem.
Fire Risk: This plant has a high flammability rating and should not be planted within the defensible space of your home. Select plants with a low flammability rating for the sites nearest your home.
Quick ID Hints:
- Pine tree with elongated needles in threes
Insect, Diseases, and Other Plant Problems: This tree is susceptible to wind, ice, and storm damage. However, it has no serious pest or disease problems in landscapes.
