Foliage season:

American smoke tree has a surprisingly limited natural range in Arkansas, Missouri, Oklahoma but its an exceedingly adaptable tree. Large round leaves are soft green when they emerge. In mid summer the tips of the branches are covered in clouds of beige smoke- which is not as prolific as the hybrids or the species Cotinus coggygria. Rounded medium sized tree to 22′ tall and handsome. Moderately slow growing 1-2′ per year when young. Full sun and regular irrigation to established then fully summer drought established. Deep rich soils yield the best performance. Autumn is its time of true glory. The large soft leaves transform into electric shades of orange/red/yellow. It holds this color for weeks before dropping. An amazing show that outshines just about any other deciduous tree. Limited supply. Accepts some summer irrigation. It is being used as a street tree in Portland, where its arboreal habit is superior to Cotinus coggygria and its hybrids.
