The Cotinus or Smoke Tree is a remarkable bush known for its deciduous, colourful foliage that changes throughout the seasons and its summer flowering in evanescent plumes reminiscent of wigs. It forms a bushy shrub averaging 1 to 6 m in height and nearly as wide, depending on the variety. Whether they have purple foliage like the famous Cotinus ‘Royal Purple’, red in ‘Grace’, or golden yellow in Cotinus ‘Golden Spirit’, all put on a show from summer to autumn, especially when the first frosts ignite their colours like fire. The Cotinus coggygria comes in about ten cultivars and a few hybrids, all perfect for brightening up free-standing hedges or shrub borders. There are also some dwarf varieties well-suited for small spaces and container cultivation. Vigorous and hardy down to -20°C, the Cotinus is easy to grow in full sun or partial shade in any well-drained soil.

According to the flowering period

The Cotinus is renowned for its spectacular, plume-like flowering reminiscent of wigs. It is a remarkable bush when vaporous panicles crown its foliage from summer to autumn. In May-June, the pedicels of the sterile flowers elongate into long filaments, forming an ethereal hair that enhances the silhouette of the bush. The flowering is spring or summer, depending on the varieties, starting and ending more or less early:

According to the colour of the flowers

The cotinus presents a flowering that resembles cotton, evoking clouds of smoke, candy floss, or airy wigs, to the extent that the English refer to it as the “smoke tree.” It flowers in white, most often in tea rose, in purplish pink, and more rarely in coppery orange.

According to the colour of the foliage

It is undoubtedly the colour of the foliage that inspires you the most when choosing a Cotinus. Although it is deciduous, it enchants us with the palette of colours it offers. In Cotinus, the foliage plays a true symphony from spring to autumn. The deciduous leaves appear as early as April, are ovate in shape, and measure 5 to 15 cm long. Some develop purplish foliage, while others burst into golden yellow. Their hues change with the seasons, taking on warm shades from orange-red to scarlet, and even bluish-purple as autumn arrives. All Cotinus display beautiful colours in autumn before losing their leaves.

Purple Foliage

Many Cotinus are adorned with purple foliage. With their deep-coloured attire, they add density to a border or create striking contrasts. The colours will be even more pronounced when the bush is exposed to sunlight. Their leaves may appear almost black. Some delicately veined leaves will be enhanced when light passes through them. This purple foliage is perfect in a wild garden, as well as in a modern garden, adding a subtle, dark, contemporary touch.

Golden Foliage

The varieties with yellow or golden foliage bring a lot of brightness to the garden. All are deciduous, and they always take on beautiful warm shades in autumn before losing their leaves.

Green Foliage

The Cotinus coggygria ‘Flamissimo®’ is somewhat of an exception as it unfolds its large purplish green foliage in spring, gradually taking on increasingly warm hues, ranging from vermilion red to orange, finishing in bright yellow in autumn.

According to the pruning and use

Smoke trees form bushy shrubs with a slightly gangly silhouette. The habit is very ramified. Of medium growth, they reach their adult size after about 10 years. The smoke tree generally does not exceed six metres in height, except for the species c. obovatus, which can climb up to 10 m. If not pruned regularly, Cotinus can become quite imposing and form a huge dome. Good annual pruning encourages a much more compact and dense habit. In a free hedge, as a focal point in a shrub bed, or even in a pot on a terrace, Cotinus offers numerous possibilities. The use in pots or containers is entirely possible, as some dwarf varieties are perfectly suited for pot cultivation or small spaces.

The largest varieties of Cotinus

They form large bushy shrubs that are more or less upright, averaging 3 to 6 m in height and nearly the same in width. Their dense foliage makes them interesting for adding colour and dynamism to your free hedges and as a backdrop for your beds. Majestic, they will also find their place on a large bank or as solitary specimens.

According to hardiness

The Smoke Trees can withstand very low temperatures of around -20 °C (Zone 6a (-23.3°C to -20.6°C)), ensuring excellent hardiness in all regions. They truly feel at home in our climates, even the harshest ones. However, their hardiness may be reduced in areas where winter is cold and rainy, as well as in clay soils, as they are sensitive to heavy soils, particularly saturated with water during the bad season.
