Gaultheria procumbens (Eastern Teaberry, Checkerberry, Boxberry, or American Wintergreen) is a species of Gaultheria native to northeastern North America from Newfoundland west to southeastern Manitoba, and south to Alabama.  It is a member of the Ericaceae (heath family).
It is a small low-growing shrub, typically reaching 10–15 cm tall. The leaves are evergreen, elliptic to ovate, 2–5 cm long and 1–2 cm broad, with a distinct oil of wintergreen scent. The flowers are bell-shaped, 5 mm long, white, borne solitary or in short racemes. The berry-like fruit is actually a dry capsule surrounded by fleshy calyx, 6–9 mm diameter.
It grows in acid soil, in pine or hardwood forests, although it generally produces fruit only in sunnier areas.
G. procumbens spreads by means of long rhizomes which are within the top 20-30 mm of soil. Because of the shallow nature of the rhizomes, it does not survive most forest fires, but a brief or mild fire may leave rhizomes intact, from which the plant can regrow even if the above-ground shrub was consumed.
The fruits are edible, with a minty flavour, and the leaves and branches make a fine herbal tea, through normal drying and infusion process. In order for the leaves to produce more than a whiff of the methyl salicylate, they need to be fermented in warm water for several days before drinking.
Teaberry is also an ice cream flavor in regions where the plant grows. It also inspired the name of Clark's Teaberry chewing gum.
Wintergreen is not taken in large quantities by any species of wildlife, but the regularity of its use enhances its importance. Its fruit persists through the winter and it is one of the few sources of green leaves in winter. White-tailed deer browse wintergreen throughout its range, and in some localities it is an important winter food. Other animals that eat wintergreen are wild turkey, sharp-tailed grouse, northern bobwhite, ring-necked pheasant, black bear, white-footed mouse, and red fox. Wintergreen is a favorite food of the eastern chipmunk, and the leaves are a minor winter food of the gray squirrel in Virginia.
Other common names include: Canada tea, checkerberry, deerberry, ground berry, hillberry, mountain tea, partridge berry, spiceberry, spicy wintergreen, spring wintergreen, wax cluster, and teaberry.
While this plant is also known as partridge berry, that name more often refers to the ground cover Mitchella repens.
