Pinus thunbergii (Pinaceae) is a two-needled pine native to Japan. It grows to about 80 feet tall with a broad, irregular crown and dark, deeply furrowed bark. The stiff, dark green needles (3 to 5 inches) and prominent white terminal buds ("candles") are distinctive.
Japanese black pine is valued for its salt tolerance, making it one of the best pines for coastal plantings. It tolerates urban conditions, sandy soils, and wind exposure. It grows in full sun. The species is widely used in Japanese-style gardens and is a classic subject for cloud pruning and bonsai. Pine wilt nematode is a significant threat in some regions. Hardy in Zones 4 to 9.
