The “Coral Bark” Japanese Maple (Acer palmatum ‘Sango Kaku’) is an eye-catching and elegant cultivar prized for its brilliant coral-red bark and vibrant seasonal color. This stunning tree brings year-round interest to the landscape — glowing in winter with vivid red stems and transitioning through a kaleidoscope of foliage colors through the seasons.

Here are some key features and information about the Coral Bark Japanese Maple:

Foliage: The Coral Bark Japanese Maple showcases bright green leaves that emerge in spring, often with soft red edges. As the seasons progress, the foliage turns a lush medium green through summer before transitioning to stunning golden-yellow tones in fall, often with hints of orange and red — creating a breathtaking autumn display.

Bark: The standout feature of this tree is its coral-red bark, most vibrant during the colder months. As the leaves drop in winter, the colorful bark becomes a focal point in the garden, adding warmth and structure to the landscape.

Form: This upright, vase-shaped Japanese Maple has a graceful branching pattern that complements both formal and natural garden designs. Its structure allows the colorful bark and fine foliage to shine year-round.

Size: Coral Bark typically reaches 15–25 feet tall with a spread of 12–20 feet, making it an excellent choice for medium-sized gardens, courtyards, or as a small shade tree.

Sun Requirements: Prefers partial shade to full sun. In warmer climates, providing afternoon shade helps protect the foliage from leaf scorch and maintains vibrant bark coloration.

Soil: Grows best in moist, well-drained, slightly acidic to neutral soil. Incorporating organic matter will enhance soil health and water retention.

Hardiness: Hardy in USDA Zones 5–8.

Landscape Use: Perfect as a specimen tree, focal point near patios, or in Japanese-inspired gardens. Its four-season interest — from spring leaves to fiery bark — makes it an exceptional choice for year-round beauty.

Pruning: Minimal pruning is needed. Light shaping in late winter or early spring can help maintain structure and remove dead or crossing branches without disturbing its natural form.

Disease Resistance: Coral Bark is generally disease-resistant and easy to care for when planted in suitable conditions. Good watering habits and soil drainage help prevent root rot and stress-related issues.

When planting the Coral Bark Japanese Maple, choose a site that highlights its brilliant winter bark. Add mulch around the base to retain moisture and moderate soil temperature, and enjoy the ever-changing colors of this landscape gem throughout the year!
