Pinus Thunbergii - Japanese Black Pines

Pinus thunbergii – Japanese Black Pine is a striking evergreen conifer known for its twisted, dark green needles, textured black bark, and irregular, windswept growth habit. Reaching heights of 8–20 metres in open landscapes (or kept compact through pruning), it delivers unmatched visual drama, particularly in coastal gardens, Asian-inspired designs, or modern sculptural landscapes.

Its dense, stiff needles grow in pairs, forming bold clusters along gnarled branches. The bark matures into scaly, dark grey-black plates, offering year-round structure and contrast. Though slow-growing initially, this species is long-lived, highly adaptable, and incredibly resilient in tough conditions.

Perfect for feature planting, bonsai training, or niwaki-style shaping, Japanese Black Pine handles coastal exposure, poor soils, urban pollution, and drought once established. It produces small pollen cones in spring, followed by woody female cones that mature over two years.
