Chinese dogwood

Chinese dogwood (Latin: Cornus kousa Hance subsp. chinensis) is a perennial deciduous tree or shrub belonging to the Cornaceae family. It is highly esteemed in both horticulture and landscaping for its spectacular floral display and unique, edible fruits, serving as both an ornamental and a minor fruit crop.

Originating from the eastern provinces of China, this plant has been introduced to various temperate climates worldwide. It thrives in well-protected sites that receive full sunlight but can tolerate partial shade in regions with intense summer heat. The Chinese subspecies is specifically known for its larger, more persistent bracts compared to the typical Cornus kousa.

The botanical characteristics include a vase-shaped habit that matures into a rounded canopy. Leaves are ovate with distinct veins and turn vibrant shades of red and purple in autumn. The "flowers" are actually small, inconspicuous florets surrounded by four showy white or creamy bracts. Following the bloom, the tree produces fleshy, red, strawberry-like fruits that are considered edible and nutritious.

Agricultural success depends on providing rich, well-draining, and acidic soil. The tree is intolerant of standing water, making proper soil drainage a priority. Cultivation practices include:

• Regular irrigation during establishment and dry spells.
• Application of organic mulch to keep root zones cool.
• Annual fertilization with balanced nutrients in early spring.
• Occasional pruning to maintain desired shape and improve airflow.

In landscape use, it serves as an excellent focal point or specimen plant. From a horticultural perspective, it is susceptible to certain fungal issues like powdery mildew and dogwood anthracnose, especially in humid environments. Pest management focuses on monitoring for borers and scale insects, which can affect the tree's vitality if left unchecked.
