Black Pine is an evergreen, gymnosperm tree that grows 20-50' tall. It has a flat-topped pyramidal form with no prominent central leader. As it ages, it will be irregular and asymmetrical, with a spreading crown with pendulous branches. This specimen is noted for its silky whitish candle-like terminal buds. The contrast with the foliage gives an interesting look. Young foliage candles are upright. A dense plant that serves as a great screening. It's very tolerant of salt spray and transplants easily. This plant is commonly misidentified as P. nigra in trade, a species easily distinguished by acentral leader and spring candles. It is utilized in coastal areas and seashore plantings, reclaiming dunes, and as a specimen plant. This plant prefers full sun and moist, well-drained, fertile soils. It is tolerant of sand, heat, drought, salt. This plant has a medium growth rate.
Though not often, Diplodia tip blight, rusts, cankers, blight and leaf cast are some issues affecting this plants health. Some pests include pinewood nematodes, caterpillars, sawfly, scale, mealybugs, borers, miners and weevils.
