Gaultheria procumbens (Checkerberry, Teaberry or Creeping Wintergreen)


Michael's Opinion

A low growing shrub often used as a ground cover. Once established Gaultheria procumbens grows readily and can, in ideal conditions, be considered invasive. The deep lustrous green foliage provides an excellent backdrop for the scarlet berries.

Description and Growing Information

General DescriptionG. procumbens has dark green, low growing foliage that develops a purple tinge in the autumn. When the foliage is crushed, it smells of winterberry. Bright red berries appear on the plant beginning in July and remain and persist through the winter into April: the berries are often used in medicinal teas. Small bell shaped, white to pink flowers appear on the plant in mid-summer.
ID CharacteristicIt is a low growing plant with dark green jagged toothed foliage and scarlet red berries.
ShapeLow mounding to trailing evergreen groundcover shrub of approximately 5 - 15 cm.
LandscapeGaultheria procumbens is commonly grown as a ground cover, thriving in light shade or full sun. The bright red berries provide excellent late season interest against the backdrop of its dark green leaves and persist well into lasting the winter months. As a ground cover it may be considered according to some literature) invasive in ideal conditions however I have never experienced this.
PropagationSeedlings require a cold stratification of 4°C for approximately four to ten weeks. Cuttings should be taken spring. Both methods can be difficult thus propagation is frequently achieved through division.
CultivationGaultheria procumbens thrives in acid, sandy soils that are well drained and once established can tolerate periods of drought. It does well in partial shade to full sun and therefore grows as an under larger trees in its natural habitat.
PestsGaultheria procumbens had no notable pests or diseases.
