Cotinus (Smoke Bush)
The deciduous shrub Cotinus coggyrio (AGM) has gained its common name due to its plume-like inflorescences which, by autumn, have turned a smoke-grey.
Cotinus coggyria (AGM) has been an old favourite since its introduction to Europe in 1656. It has rounded mid-green leaves that take on fine autumn colourThere are a considerable number of forms: ‘Royal Purple’ (AGM) has deep wine-red foliage which, as autumn approaches, takes on a more reddish hue. Also similar is Notcutt’s Variety’. The popular ‘Velvet Cloak’ has deep red-purple foliage that colours well in autumn. One must not overlook the hybrid ‘Flame’ (AGM), which produces clusters of pink. Its main attraction is in the autumn when the leaves turn a brilliant orange-red before they fall.
