Native

Heartleaf willow is a highly variable willow species and as a result can be difficult to identify. It is native to most parts of Canada and the United States. The shrubby tree or tall shrub typically grows 2-4 meters tall. It is found in swamps, shorelines, dunes, ditches, stream banks, and other wet, sometimes calcareous sites; rarely upland. Heartleaf Willow typically has silvery galls caused by small insects.
