Did you know?
The root of rough avens has been used medicinally in the past to treat all sorts of illnesses. One of its common names, chocolate root, refers to the chocolate-like beverage it produces when the root is boiled in milk. There are many historical sites for this species in New York so it may be overlooked because it resembles two common avens species, Geum laciniatum and Geum canadense.
