Cotinus coggygria, or smoketree, is non-native to Ontario, with potentially invasive tendencies. This shrub or small tree originates from Europe and Asia, and is known for its pest and disease resistance. It tolerates a wide range of soil conditions, including a pH between 4-8, and different soil textures for sandy to clay soil. To maintain its shape, regular pruning is required. Caution should be used when pruning as its resinous sap may irritate the skin on contact. An alternative could be Cotinus obovatus.
