Cotinus coggygria

Cotinus coggygria, syn. "Rhus cotinus", the European smoketree, Eurasian smoketree, smoke tree, smoke bush, Venetian sumach, or dyer's sumach, is a species of flowering plant in the family Anacardiaceae, native to a large area from southern Europe, east across central Asia and the Himalayas to northern China.
Description.
It is a multiple-branching deciduous shrub growing to tall with an open, spreading, irregular habit, only rarely forming a small tree. The leaves are 3–8 cm long rounded ovals, green with a waxy glaucous sheen. The autumn colour can be strikingly varied, from peach and yellow to scarlet. The flowers are numerous, produced in large inflorescences long; each flower 5–10 mm in diameter, with five pale yellow petals. Most of the flowers in each inflorescence abort, elongating into yellowish-pink to pinkish-purple feathery plumes (when viewed en masse these have a wispy 'smoke-like' appearance, hence the common name "smoke tree") which surround the small (2–3 mm) drupaceous fruit that do develop.
Cultivation and uses.
It is commonly grown as an ornamental plant, with several cultivars available. Many of these have been selected for purple foliage and flowers.
The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:-
The wood was formerly used to make the yellow dye called young fustic. 
Fossil record.
Macrofossils of "Cotinus coggygria" from the early Pliocene epoch have been found in Western Georgia in the Caucasus region.
