Wild Bergamot, as a member of the mint family, has square stems. The odor of the crushed leaves is a combination of mint and citrus. American Indian tribes used this plant as a decongestant. They also used it to cure headaches, colds, abdominal pains, acne, and fever. I found this cluster of plants by Trout Lake in Bovey, MN. As you can see, bees like this plant. I have also seen hummingbirds visiting the Bergamot in our wildflower garden.
