About plant names...

Japanese red pine is native, not surprisingly, to Japan, along with the Korean peninsula, northeastern China, and extreme southeastern Russia. In Japan it is called aka-matsu (アカマツ); in China 赤松; and in Korea 소나무: “red pine.” It is not found in the wild in North America, though it is widely planted in gardens. This cultivated variety is called Umbraculifera because of its umbrella-like crown. There are many other cultivars.

Plants: Small trees 10-20' (3-6.1 m) tall and 15-25' (4.6-7.6 m) around. In the wild it can reach 100' (30 m). It has orange-red bark, and irregular, multiply branched but graceful form.

Leaves: Needles are bright green, in bundles of 2, 3-4½" (8-12 cm) long.

Fruits: Cones are oval or oblong, copious, and 1½-2½" (4-7 cm) long.
