Wintergreen is a spreading, evergreen, rhizomatous shrub which grows 4
to 8 inches (10-20 cm) tall [5,11,28]. Wintergreen creeps along the
ground, forming a dense carpet of shiny leaves that are 2 to 6 inches
(5-15 cm) long. The small flowers are less than 0.5 inches (1.2 cm)
long and are borne at the base of the leaves [27]. The fruit is
berrylike capsule with a large fleshy calyx [45]. The roots are 1 inch
(2.5 cm) or less in depth [14,31].
