Cornus controversa | Giant dogwood

The Cornus controversa, commonly known as the giant dogwood or table dogwood, hails from the majestic regions of the Himalayas, China, and Japan. This deciduous shrub is revered for its distinctive tiered branches and is a true spectacle in any garden. Featuring a striking, upright growth habit, the giant dogwood makes a dramatic statement when placed as a solitary feature or within a border composition.

Its elegant appearance is highlighted in the summer months, when it blossoms with clusters of creamy white flowers, followed by attractive blue-black fruit in the autumn. The foliage also puts on a seasonal show, transitioning from green in spring and summer to a vibrant purple in the autumn, providing a year-round interest.

Key Features

Key features of the Cornus controversa include:

The table dogwood reaches an ultimate height of approximately 5 meters, making it a grand addition to landscapes.
Its white flower clusters bloom in June and July, adding a touch of elegance and charm to your garden.
Although deciduous, it maintains its visual appeal throughout the year with its changing foliage colors and fruit-bearing qualities.
The plant's fruit, which ripens in the autumn, is a mix of black and blue, adding an interesting dimension to the autumnal garden palette.
It has an average water need, making it suitable for gardeners who prefer plants that do not require constant attention.
The giant dogwood is adaptable to all well-drained soil types and thrives in locations with full sun to partial shade.

Tips

For the best growth and flower production, plant Cornus controversa in a spot that receives full sun to partial shade with well-drained soil.
While it does not require extensive pruning, occasional maintenance may be necessary to shape the plant or remove any dead or damaged wood.
Ensure that the plant is watered regularly, especially during dry spells, as it is not drought-resistant.
Propagation of the giant dogwood can be achieved through grafting, a meticulous process that combines the desirable characteristics of two plants for a more resilient offspring.
As autumn approaches, anticipate the transformation of the foliage to a stunning purple, adding a rich contrast to your garden's color scheme.

Ideal placement of a Cornus controversa

For optimal growth, Cornus controversa should be sited where it can bask in full sun or dapple in partial shade. These conditions will ensure the most vigorous growth and abundant flowering. The soil should be well-drained, yet this adaptable shrub can thrive in a range of soil types. When choosing a location, consider the upright growth habit and potential height of up to 5 meters, allowing ample space for the plant to mature gracefully. The area should be sheltered from harsh winds to protect its elegant structure.

How do I plant a Cornus controversa?

When planting Cornus controversa, select a well-drained spot in either sun or partial shade to accommodate its growth up to 5 meters in height. Being pot-grown, the shrub can be planted any time of year sans frost. Space is crucial for this species to develop its characteristic layered branches, so ensure ample room if planting multiples. Initially, maintain an even moisture level to help establish a strong root system, but be mindful to avoid overwatering. With the proper conditions, this shrub will exhibit its striking white flowers in summer, followed by a display of purple foliage and dark fruit come autumn.

Pruning a Cornus controversa

Cornus controversa is a low-maintenance species that typically thrives without the need for significant pruning. To maintain its natural, tiered structure, only remove dead, damaged, or crossing branches. This should be done during the dormant season to prevent stress to the plant. If shaping is desired, perform light pruning after the flowering period to avoid cutting off next year's blooms. Any substantial pruning to reduce size or rejuvenate an older shrub should be done sparingly and over several seasons to preserve the plant's health and appearance.

Watering a Cornus controversa

Cornus controversa thrives with consistent moisture, particularly in well-drained soil and in both sun and partial shade. Its average water needs mean that regular watering is essential, especially when the plant is establishing its root system in the initial years after planting. During periods of dry weather, increase watering frequency to maintain soil moisture levels but avoid waterlogging, which can be detrimental. Mulching around the base can help retain moisture and protect the roots. Once mature, this species can tolerate occasional dry spells but should not be allowed to dry out completely.

Fertilising a Cornus controversa

To ensure the vigorous growth and prolific flowering of this species, it is critical to follow a regular fertilizing schedule. Apply a balanced, slow-release fertilizer in early spring to support the initial flush of foliage and prepare the plant for the blooming season. A second application in late spring can further bolster the plant's development as it enters the summer months.

Because Cornus controversa produces an array of fruits in the autumn, providing it with the proper nutrients is also beneficial for fruit set and quality. When fertilizing, distribute the product evenly around the base of the plant, taking care not to concentrate it too close to the trunk to prevent root burn. Watering after application helps to integrate the nutrients into the soil, allowing the roots to absorb them more effectively.

The characteristics of a Cornus controversa

Cornus controversa is known for its striking horizontal tiers of branches, which give it a unique architectural appearance in the landscape. This species thrives when given ample space to showcase its full spread, creating a dramatic, layered canopy. The white springtime blossoms are complemented by the foliage that transitions from a lush green to a vibrant autumnal display. Furthermore, the black fruits produced are a visual treat and serve as a food source for local bird species, enhancing the ecological value of your garden.
