Acer palmatum 'Nishiki Gawa', commonly known as the Pine Bark Japanese Maple, is a striking cultivar of Japanese maple prized for its unique, rough, pine-like bark and vibrant seasonal foliage. This upright, deciduous tree typically grows to a height of 12-18 feet over time, with a spread of about 12-15 feet, though its size can vary depending on climate and care.
The standout feature of 'Nishiki Gawa' is its bark, which begins to develop a craggy, fissured texture after about three years, becoming more pronounced as the tree matures. This bark is often compared to that of the Japanese black pine, giving the tree a rugged, aged appearance that makes it especially popular for bonsai enthusiasts. The foliage emerges light green in spring, sometimes with subtle red edging, and turns a brilliant mix of red, orange, and yellow in the fall, providing stunning seasonal interest. The leaves are small, lobed, and palmate, typical of Acer palmatum varieties.
This maple thrives in moist, well-drained, slightly acidic soils and prefers full sun to partial shade. In cooler climates, it can handle full sun, but in hotter regions, some afternoon shade is beneficial to prevent leaf scorch. It’s hardy to USDA Zone 5 (down to -20°F), making it suitable for a range of temperate environments. 'Nishiki Gawa' is relatively low-maintenance, requiring minimal pruning—best done in late fall or winter to avoid sap bleeding—and regular watering to keep the soil consistently moist, especially in summer.
Its distinctive bark and year-round appeal, from summer greenery to fall color and winter structure, make 'Nishiki Gawa' a standout choice for gardens, containers, or as a specimen tree. It’s also noted for being one of the most popular Japanese maples in Japan, blending classic beauty with a touch of rugged charm.
