|Gaultheria procumbens in Hammond, Indiana|
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).
Growth habit 
It is a small low-growing shrub, typically reaching 10–15 centimeters (3.9–5.9 in) 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 is a calcifuge, favoring acid soil, in pine or hardwood forests, although it generally produces fruit only in sunnier areas. It often grows as part of the heath complex in an oak-heath forest. 
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 flavor, and the leaves and branches make a fine tisane, through normal drying and infusion process. For the leaves to yield significant amounts of their essential oil, they need to be fermented for at least 3 days.
Wildlife value 
Wintergreen is not taken in large quantities by any species of wildlife, but the regularity of its use enhances its importance. Its fruit persist 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.
