Japanese Black Pine

Japanese Black Pine (Pinus thunbergii)

Japanese Black Pine (Pinus thunbergii) is a classic, coastal-hardy conifer known for its rugged form, dark green needles, and striking gray-black bark. Native to coastal Japan and South Korea, this species is prized for its resilience in harsh conditions and its natural ability to develop dramatic, windswept shapes that bring character to the landscape. It has long been a staple in Japanese gardens, bonsai culture, and coastal plantings across the world.

Distinctive Features

Japanese Black Pine grows in an irregular, picturesque form, often developing strong lateral branching and a broad canopy with age. Mature trees typically reach 20 to 40 feet tall and 20 to 30 feet wide, though they can grow taller in optimal conditions. The stiff, two-needle bundles are dark green and densely held, providing year-round color and texture. The bark becomes deeply fissured and silvery-gray with age, adding ornamental value in winter.
