Acorus americanus is a wetland perennial with broad blade-like foliage resembling that of Iris versicolor or Typha angustifolia. It can be identified easily by breaking the foliage, which is uniquely aromatic. Acorus americanus can be distinguished from the European Acorus calamus by the several indistinct ribs in its foliage. By contrast, Acorus calamus has a single distinct mid rib. Acorus americanus is typically found in the shallow waters and shorelines of wetlands across northern North America, as far south as Virginia. Acorus americanus has proved itself as an excellent erosion control species for the edges of bioretention basin and ponds. It provides effective soil stabilization and dense cover for wildlife. Its aromatic foliage makes it an ideal plant for sites with deer pressure.
