Identification: Wintergreen is a native North American evergreen shrub; the creeping stems send up erect branches, 2-6 inches high, which bear alternate, oval, leathery leaves with serrate (and sometimes bristly) margins. Both the leaves and the solitary, nodding, white, bell-shaped, flowers grow in the axils of the leaves near the tops of the branches. Flowering time is from May to September. The edible fruit following the flowers is a dry, scarlet, berrylike capsule about 1/3 inch across. The whole plant is pungent in taste the spiciness being due to the volatile oil.
