A large, fast-growing tree of forests, reaching heights of 80 feet and a trunk to 2 feet in diameter, with a dense, rounded crown of dark, blue-green foliage. Prefers well-drained soils. Important southern yellow pine.
The primary guide to determine plant hardiness is the USDA Hardiness Zone Map, which divides the United States into ten zones based on average minimum temperatures. Each zone is then subdivided into A and B sections. A plant is said to be hardy if it can tolerate the lowest average winter temperature that occurs in a zone. Hardiness is affected by duration and intensity of sunlight; amount and timing of rainfall; length and severity of summer drought; soil characteristics; slope; frost occurrence; humidity; and cultural practices.
