Pinus Nigra is a large Conifer at LEADS Persistent , reaching 20 to 55 meters (66 to 180 feet) high at maturity and extending to 6 to 12 M (20 to 39 feet) wide. The Bark is gray to yellow-brown and is largely split by flashed cracks in scaly plates, more and more cracked with age. The Leaves ("needles") are finer and more flexible in Western populations. ^{[ citation nécessaire ]}

The ovulation and pollen cones appear from May to June. Mature seed cones measure 5–10 centimeters (2–4 inches) (rarely up to 11 cm) long, with rounded scales; They mature green with pale gray or yellow chamois from September to November, about 18 months after pollination. The seeds are dark gray, 6–8 millimeters ( 1 ⁄ 4 - 5 ⁄ 16 PO  ) long, with a chamois yellow wing of 20–25 mm ( 3 ⁄ 4 –1 PO) long; They are dispersed by the wind when the cones open from December to April. Maturity is reached at 15–40 years; Large seed crops are produced at intervals from 2 to 5 years old. 

Pinus Nigra has moderately rapid growth, about 30–70 cm (12–28 in) per year. It generally has a rounded conical shape, which becomes irregular with age. The tree can have a long service life, some trees over 500 years old.
