Wintergreen

Wintergreen (Gaultheria procumbens, Ericaceae) is a prostrate, stoloniferous evergreen groundcover native to eastern North America from Newfoundland to Manitoba and south to Georgia and Alabama, reaching about 1 foot tall. Small urn-shaped white to pinkish flowers appear from March to May, followed by bright red berries. Foliage emits the characteristic wintergreen fragrance when crushed.

Wintergreen grows in part shade on well-drained, acidic soil (pH 4.0 to 6.5) with low water needs, hardy in Zones 3a to 8b. Growth is slow. Edibility and medicinal ratings are high (4 and 3 respectively), though the essential oil is toxic in large doses and poses a risk to individuals with aspirin allergies. No significant pest or disease issues are documented.
