The outstanding feature of Eurasian smoke tree is the large, airy, plume-like stalks that hold the small flowers. These are covered with hairs that provide the appearance of a puff of smoke. Eurasian smoke tree will grow as either a single-trunked tree or a multi-stemmed shrub. Although it may suffer from dieback in cold winters, vigorous stems bounce back to life in spring.

Tree & Plant Care
Avoid planting in low-lying areas where soil remains wet.
Prune cultivars with colored foliage heavily to produce new growth (which produces best color).
Disease, pests and problems
May suffer from dieback in cold winters.
Native geographic location and habitat
Native to Europe and Asia
Bark color and texture
Bark is relatively smooth and light gray when young; takes on a more flaky appearance with age.
Leaf or needle arrangement, size, shape, and texture
Simple, alternate leaves; oval or slightly elongated, 1 to 3 inches long.
Color is green on the species; will vary by cultivar (some red, purple or yellow).
Fall color is reddish-purple on the species.
Flower arrangement, shape, and size
The actual flowers are tiny and not showy. The structure that holds the flowers is covered with hairs and this is the actual 'smoke' for which the tree is named.
Fruit, cone, nut, and seed descriptions
The true fruit are small and dry. Again, the structure that holds the fruit is the source of the 'smoke' of this plant.
Cultivars and their differences
Nordine (Cotinus coggygria ‘Nordine’): One of the hardiest of the purple-leaf forms, selected from The Morton Arboretum collections; oval to slightly elongated purplish-red leaves hold color well into the summer and then change to an orange-yellow in the fall.
Royal Purple (Cotinus coggygria ‘Royal Purple’): Leaves are dark purple in summer and red-purple in fall; 'smoke' is also reddish purple.
Velvet Cloak (Cotinus coggygria ‘Velvet Cloak’): Dark, oval to slightly elongated purple leaves maintain color throughout the summer; fall color is a reddish-purple; large, purple-pink, airy, plume-like flower stalk clusters provide interest all summer.
