Acer palmatum Sango Kaku

Description:
Coral Bark Maple (Acer palmatum 'Sango Kaku') is a distinctive Japanese maple known for its vibrant, coral-red bark that brings striking winter interest to the landscape. This deciduous tree has an upright, vase-shaped form and showcases beautiful, palmate leaves that change color throughout the seasons. Sango Kaku is highly valued for both its foliage and its colorful bark, making it a standout specimen in gardens, borders, and Japanese-inspired landscapes.

Flowers:
In spring, 'Sango Kaku' produces small, purple-red flowers in clusters. While not a primary feature, these delicate blooms add a subtle charm to the tree as the leaves begin to emerge.

Foliage:
The tree features finely lobed, light green leaves in spring and summer. In autumn, the foliage transforms into vivid shades of yellow and orange, creating a beautiful contrast against the red bark. The leaf texture is soft, providing a delicate, lacy appearance that enhances the tree’s graceful form.

Bark:
One of the most distinctive features of Sango Kaku is its bright coral-red bark, which intensifies in color during the winter months. The vibrant bark adds visual interest and color to the landscape, especially in colder seasons when other plants are dormant.

Fruit:
After flowering, the tree produces small, winged samaras (helicopter seeds) in late summer to early autumn. These seeds add a touch of natural charm but are not a prominent feature of the tree.

Form and Size:
Sango Kaku has an upright, vase-shaped growth habit, typically reaching a height of 5 to 7 meters with a spread of 4 to 6 meters. Its moderate size and unique seasonal interest make it suitable as a focal point in gardens, as well as in mixed borders.

Growing Conditions:
This Japanese maple thrives in partial shade to full sun, though some afternoon shade is beneficial in warmer climates to prevent leaf scorch. It prefers moist, well-draining, slightly acidic soil enriched with organic matter. Regular watering during dry periods is essential to maintain healthy foliage and bark color.

Uses:
Coral Bark Maple is ideal as a feature tree in garden beds, Japanese-style landscapes, and as a specimen in mixed borders. Its winter bark color and autumn foliage make it a valuable addition to any garden, providing year-round interest.

Maintenance:
This variety is relatively low-maintenance. Light pruning in late winter can help maintain shape and remove any dead or crossing branches. Mulching around the base helps retain soil moisture and protect roots, and an acid-loving fertilizer in spring promotes healthy growth.

Notes:
Sango Kaku is celebrated for its vibrant coral bark, which adds color and structure to winter gardens. Its colorful foliage and graceful form make it a popular choice for gardeners looking to add seasonal beauty to landscapes.

Companion Plants:
Pairs well with other shade-tolerant plants such as Rhododendrons, Hostas, and Ferns. It also complements other Japanese maples and woodland perennials, creating a layered, harmonious effect in garden beds.
