Noteworthy Characteristics

Pinus densiflora, commonly called Japanese red pine, is perhaps the most common tree growing in Japan. It will soar to 100’ in the wild, but in cultivation is more likely to top out at 40-60’ tall. In its early years, this is a medium growing pine (to 12” per year). It is noted for its irregular but frequently graceful form and its orange-red bark. Often multi-trunked at the base, this tree features a broad-rounded shape, horizontally spreading branching and a somewhat flattened mature crown. Trunks often lean. Bark matures to gray-fissured at the base. Bright green needles (to 3-5” long) appear in bundles of two. Oval to oblong cones (to 2” long) are often plentiful. Common name is in reference to the attractive orange-red bark that exfoliates with age. Needles may yellow in winter.

Genus name comes from the Latin name for pines.

Specific epithet means densely-flowered, which is odd being used for a non-flowering plant (a conifer). It probably refers to the species' abundant production of small cones.

‘Low Glow’ is a dwarf cultivar that forms a dense, compact, rounded mound of foliage to 3-4’ tall over the first 10 years. It is very slow growing (3-5” per year). Seedling from a witch’s broom.


Healthy, well-maintained trees in their native environment usually have few major problems. Most pines can be difficult to grow well in the St. Louis area in large part because of soil and climate.
