General Appearance

The Beni Kawa Japanese maple is an upright tree with a graceful, spreading canopy.

Its most striking feature is its coral-red bark, which deepens over winter and provides a stunning contrast to its bright green leaves in spring and summer.

The leaves are palmate, meaning they have several lobes radiating from a single point, much like a hand. This gives the tree a delicate, lacy appearance that is particularly beautiful when backlit by the sun.

Growth Rate & Mature Size

Growing at a rather slow rate, the Beni Kawa Japanese maple can eventually reach a mature height of about 15 feet and a width of 10-15 feet.

This makes it a medium-sized tree, perfect for smaller landscapes or as a focal point in larger gardens. Despite its less-than-speedy growth rate, patience is rewarded with a tree that provides year-round interest and beauty.

Foliage Color Through the Seasons

The foliage of the Beni Kawa Japanese maple is a sight to behold. In spring, the leaves are light green, and in summer, the leaves become bright, vibrant green.

Come fall, the leaves transition to a brilliant display of yellow-orange to red, creating a spectacular autumn show.

This changing color palette makes the tree a dynamic element in the landscape, offering visual interest throughout the year.


The Beni Kawa Japanese maple is hardy and can tolerate a range of conditions. It is suitable for USDA Hardiness Zones 5-9, meaning it can withstand winter temperatures down to -20 degrees Fahrenheit.

However, in the hotter end of its range, it appreciates some afternoon shade to protect it from scorching.

Beni Kawa Growing Conditions

The Beni Kawa Japanese maple is a versatile tree that can adapt to a variety of growing conditions. However, for optimal growth and health, there are certain conditions it prefers:

  • Sun Requirements: This tree thrives in full sun to partial shade. In hotter climates, some afternoon shade can help prevent leaf scorch.
  • Soil Preferences: The Beni Kawa prefers well-drained, slightly acidic soil. It can tolerate a range of soil types, including clay, loam, and sandy soils.

Beni Kawa Maintenance and Care

Taking care of a Beni Kawa Japanese maple involves regular watering, occasional fertilization, and some pruning:

  • Watering: Regular watering is important, especially in the first few years as the tree establishes its root system. The soil should be kept consistently moist but not overly saturated.
  • Fertilization: A slow-release, balanced fertilizer (I recommend this one) can be applied in early spring to promote healthy growth.
  • Pruning: Pruning should be done in late winter or early spring when the tree is dormant. The goal is to maintain the tree’s natural shape and remove any dead or diseased branches.
  • Winter Care: In colder climates, applying a layer of mulch around the base of the tree can help protect the roots from freezing temperatures.
