Plant Profile: Cornus kousa

The Kousa dogwood is an attractive tree that typically grows to a height of 30 feet, making it a small to medium-sized option for landscaping. Often called the Chinese dogwood, this species is related to the native flowering dogwood and can serve as a striking specimen plant or be incorporated into shrub borders.

The appearance of Kousa dogwoods changes with age. Young trees exhibit an upright, conical shape, resembling a vase. As they mature, their branches spread out horizontally, resulting in a more rounded and expansive form. These trees thrive in open spaces like lawns, although they prefer some afternoon shade. They flourish in well-drained, acidic soil and can tolerate brief periods of dryness, but they do not fare well in waterlogged conditions. Due to their shallow root systems, Kousa dogwoods are sensitive to transplantation; if relocation is necessary, it’s best to do so in early spring.

While our native dogwoods bloom in April, Kousa dogwoods flower about a month later. This tree offers year-round appeal, producing raspberry-like berries in the fall and showcasing attractive, peeling bark on its mature trunks.

For optimal growth, the soil should be well-drained yet moist. The Kousa dogwood is resistant to anthracnose and shows some resilience against deer damage, making it a valuable addition to many landscapes in the Carolinas. Don’t miss the chance to plant this stunning tree!

Potential issues include pests such as calico scale, dogwood borer, and leafhoppers, as well as diseases like leaf and flower blight, crown canker, and powdery mildew. Fallen fruits can ferment and attract yellow jackets, and seedlings may sprout prolifically beneath the tree, potentially becoming weedy.
