Family: Pinaceae Native Canopy (>40 ft)

This plant grows scattered about mountainous regions in North Carolina at elevations as high as 4,500 ft. It has an open form, irregularly pyramidal when young, and the trunk has a diameter of roughly 1 to 2 ft. The thick, gnarled branches take on a somewhat pendulous form. An irregular, globular form with twisting, gnarled, drooping branches. It has scaly, reddish-brown bark which eventually becomes black. Its stiff yellow-green needles eventually turn dark green. They grow in clusters of 3. It does best in areas with full sun. It prefers moist, well-drained soil but will tolerate a wide range of soils including poor, dry and rocky soil. This tree is salt tolerant and resistant to damage by deer. Although it can be damaged by fire, it will form sprouts from its roots and stumps. Insect, Diseases, and Other Plant Problems: This tree is susceptible to wind damage. More information on Pinus .
