This variety can reach heights of up to 30 feet and is ideal for larger landscapes. The Venus dogwood is also disease-resistant and shows improved vigor compared to its parent species.
The Cornus kousa, or kousa dogwood, exhibits a different flowering pattern. Its blooms appear later in the season, often extending into summer. Kousa dogwoods feature white, star-shaped bracts that give way to small, edible fruits in the fall. This species is also more tolerant of heat and drought compared to its flowering counterpart.
Kousa Dogwood Insights
The kousa dogwood (Cornus kousa) is a versatile tree native to Asia that has gained popularity in North America for its unique features and adaptability. It typically grows 15 to 30 feet tall and can spread about 20 to 30 feet wide, making it suitable for various landscape designs. Kousa dogwoods are particularly valued for their later blooming period, which often lasts from late spring to early summer, providing extended floral interest.
One remarkable aspect of kousa dogwoods is their ornamental fruit, which develops into small, raspberry-like berries that are edible and attract wildlife. These fruits turn from green to pinkish-red as they mature and are often sought after by birds, adding to the tree’s ecological benefits. The berries can also be used in jams and jellies, providing an additional incentive for gardeners to cultivate this species.
Kousa dogwoods are known for their striking bark, which is smooth and exfoliates in a unique pattern, revealing a lighter inner bark. This characteristic adds visual interest throughout the year, particularly in winter when the leaves have fallen. Additionally, kousa dogwoods are more resistant to certain diseases, such as dogwood anthracnose, making them a low-maintenance option for gardeners.
When planting kousa dogwoods, it’s essential to provide them with well-drained soil and adequate sunlight, although they can tolerate some shade. These trees prefer slightly acidic to neutral pH levels and should be watered regularly, especially during dry periods, to ensure healthy growth.
Cornelian Cherry Dogwood
The Cornelian cherry dogwood (Cornus mas) is a deciduous shrub or small tree native to Europe and parts of Asia. It typically grows between 15 and 25 feet in height and is known for its early spring flowers, which appear before the leaves emerge. These bright yellow flowers are a notable feature and provide a cheerful burst of color during a time when few other plants are in bloom.
Cornelian cherry dogwood is particularly valued for its edible fruit, which ripens in late summer and can be used in various culinary applications, including jams, jellies, and desserts. The fruit is small, oval, and reddish when ripe, and it attracts birds and other wildlife, enhancing the tree’s ecological role.
This species is also appreciated for its hardiness. Cornelian cherry dogwoods are tolerant of a wide range of soil types and conditions, including drought, making them an excellent choice for gardeners seeking low-maintenance options.

Dogwood Tree Care Tips
Caring for dogwood trees requires understanding their specific needs to ensure healthy growth and vibrant blooms. First and foremost, selecting the right location is critical. Dogwoods prefer well-drained, slightly acidic soils and should ideally be planted in areas that receive partial shade. Excessive sunlight can lead to leaf scorch, while overly shaded areas may hinder flowering.
Regular watering is essential, particularly during dry spells. Dogwoods have shallow roots, so it’s important to keep the soil consistently moist without waterlogging it. Mulching around the base of the tree can help retain moisture and suppress weeds, which compete for nutrients. Applying a layer of organic mulch, such as wood chips or bark, can also improve soil quality over time.
Pruning is another important aspect of dogwood care. It’s best to prune during late winter or early spring before new growth begins. Removing dead or diseased branches can enhance air circulation and reduce the risk of disease. Additionally, thinning out crowded branches can promote healthy growth and allow for better light penetration.
Fertilization can also benefit dogwoods, especially in nutrient-deficient soils. A balanced, slow-release fertilizer applied in early spring can help promote healthy growth and vibrant blooms. However, over-fertilization should be avoided, as this can lead to excessive leaf growth at the expense of flowering.
