Medium · Some experienceAbout Japanese Red Pine
Japanese Red Pine is an elegant conifer native to Japan, Korea, and northeastern China, reaching 40-60 feet, distinguished by striking orange-red flaking bark on older trunks and pairs of slender blue-green needles. Naturally forms picturesque umbrella-shaped crowns with age. The weeping cultivar 'Pendula' is especially prized. A premier specimen conifer for Japanese-style American gardens, valued for bark and form as much as foliage.

History
Pinus densiflora, Japanese red pine, grows across Japan, Korea, northeastern China, and the Russian Far East. Siebold and Zuccarini described it in 1842. In Japan the name aka-matsu, or red pine, refers to the orange-red flaking bark of the upper trunk and branches, a warm contrast to the darker black pine.
Red pine is often treated as the graceful, feminine counterpart to black pine in Japanese garden culture. It is also ecologically and gastronomically important because its roots form the essential partnership with matsutake mushrooms, whose prized fruiting bodies appear in old red-pine forests. Since the late 20th century, pine wilt nematode has devastated many stands in Japan and Korea. Cultivars such as 'Oculus-draconis', with yellow-banded dragon-eye needles, and 'Umbraculifera', the umbrella-form Tanyosho pine, brought its character into Western gardens.
