As a gardening and landscaping enthusiast, I can tell you that there is little difference between a smoke bush and a smoke tree, as they are essentially the same plant. The term “smoke bush” is often used to describe the smaller, shrub-like form of the plant, while “smoke tree” is used to refer to the larger, tree-like form. However, both names are commonly used interchangeably.
The smoke bush or smoke tree, scientifically known as Cotinus coggygria, is a deciduous shrub that belongs to the Anacardiaceae family. It is native to Southern Europe, Central China, and the Himalayas. The plant is highly valued for its unique and eye-catching foliage, which changes color throughout the year.
One of the key features of the smoke bush/tree is its distinctive smoke-like appearance when the flowers emerge. In early summer, the plant produces clusters of tiny, delicate flowers that have a feathery appearance. These flowers are surrounded by large, airy, and billowy panicles that resemble puffs of smoke, hence the common name. The flowers can range in color from creamy white to pale pink to deep purple, depending on the variety.
In terms of size, the smoke bush/tree can be grown as a shrub or a small tree, depending on how it is pruned and trained. When left unpruned, it typically forms a large shrub with multiple stems, reaching a height and spread of around 10 to 15 feet (3 to 4.5 meters). However, with proper pruning and training, it can be shaped into a small tree, with a single trunk and a more upright growth habit, reaching heights of up to 20 feet (6 meters) or even taller.
The foliage of the smoke bush/tree is another striking feature. The leaves are oval-shaped and have a slightly wavy or serrated edge. They start off as a reddish-purple color in spring, gradually turning green as summer progresses. In autumn, the leaves undergo a stunning transformation, changing to shades of orange, red, and purple, adding a vibrant burst of color to the landscape.
When it comes to cultivation, the smoke bush/tree is relatively easy to grow and care for. It prefers full sun to partial shade and well-draining soil. It is tolerant of a wide range of soil types, including sandy, loamy, or clay soils. Once established, it is fairly drought-tolerant but benefits from regular watering, especially during dry periods.
Pruning is an important aspect of maintaining the desired size and shape of the smoke bush/tree. It is best to prune in late winter or early spring before new growth begins. This allows for the removal of any dead, damaged, or overcrowded branches, as well as shaping the plant to your desired form. Regular pruning also promotes better air circulation within the plant, which can help prevent diseases.
The terms “smoke bush” and “smoke tree” are often used interchangeably to describe the same plant, Cotinus coggygria. The plant can be grown as a shrub or a small tree, and it is renowned for its unique and attractive smoke-like flowers and colorful foliage. With proper care and pruning, the smoke bush/tree can be a stunning addition to any garden or landscape.
