Characteristics and Appearance
The Kousa Dogwood Tree: A Comprehensive Guide
So, what does a healthy kousa dogwood tree look like? Let’s take a closer look at its distinctive characteristics and appearance.
Physical Description
The Kousa dogwood tree is a stunning deciduous shrub that showcases its unique characteristics through its physical appearance. Reaching mature heights of 15 to 25 feet tall and 10 to 15 feet wide, this compact tree makes an ideal choice for small gardens or landscapes.
Its shape is typically rounded, with a spread-out canopy that provides a beautiful display of leaves throughout the growing season. The branches are sturdy and relatively straight, often forming a vase-shaped crown as the tree matures.
One of the most distinctive features of the Kousa dogwood tree is its bark. The younger stems have a smooth, grayish-brown texture, while mature trunks develop a mottled, scaly appearance with age. This unique bark pattern adds an attractive layer of character to the tree’s overall appearance.
In terms of size and shape, it’s worth noting that the Kousa dogwood tree can be pruned or trained to maintain a smaller, more compact form if desired. Regular maintenance, such as annual pruning in late winter or early spring, will help encourage healthy growth and promote an even, balanced shape.

The Kousa dogwood tree’s foliage is one of its most striking features, with leaves that are typically 4-8 inches long and 2-4 inches wide. The leaf structure itself is an interesting aspect to note, as the edges are usually serrated, giving them a distinctive toothy appearance. Additionally, the leaves have a pointed tip at the end and are attached to the twig by a short petiole.
One notable feature of Kousa dogwood tree leaves is their variegation pattern, which can range from solid green to a mottled or striped combination of white, cream, or pale yellow. This colorful effect adds an extra layer of visual interest to the tree’s overall appearance. Some trees may also exhibit natural color variations depending on factors like temperature and humidity levels.
When identifying Kousa dogwood tree leaves, it’s essential to note that the shape can be slightly irregular and asymmetrical compared to more uniform leaf shapes found in other species. However, this unique characteristic only serves as a testament to the beauty of nature’s unpredictability.
Flowering Habits
One of the most striking features of the Kousa Dogwood Tree is its showy flowers. In late spring to early summer, usually around May and June, the tree bursts into bloom with clusters of small, white or pink bracts that resemble tiny petal-like structures surrounding a central cluster of tiny yellow-green flowers.
