Pinus densiflora cv. ‘Umbraculifera’
Japanese red pine
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.
