Wintergreen Moss

Gaultheria procumbens

Wintergreen moss is a low-growing evergreen groundcover shrub native to North America, typically reaching 3-6 inches tall. It features small, glossy dark green leaves and produces delicate white or pale pink flowers in summer, followed by bright red berries in fall and winter. The leaves and berries are highly aromatic and have been traditionally used for flavoring and medicinal purposes.

Water: Keep consistently moist but not waterlogged; prefers high humidity. Water regularly during growing season and reduce slightly in winter. Mulch heavily to retain moisture.
📏
Spacing: 6-12 inches
📅
Days to maturity: Not applicable; perennial groundcover established in 1-2 years
🌱
Planting depth: Plant transplants at soil surface level; seeds require stratification and light exposure

Soil

Type: Acidic, well-draining, humus-rich soil; sandy loam to peat-based substrates
pH: 4.5-5.5
Amendments:
Peat moss or composted pine bark Sand for drainage Leaf mold or compost Sulfur if soil pH is too high

Growth Stages

1

Establishment

3-6 months

Young seedlings or transplants develop root systems and begin spreading horizontally via underground runners (rhizomes)

Keep soil consistently moist; apply 2-3 inches of acidic mulch; protect from direct sun and wind; ensure high humidity

2

Vegetative Growth

6-18 months

Plant spreads horizontally, forming dense mats of small, glossy evergreen leaves; runners extend across the soil surface

Water regularly, maintain mulch layer, avoid fertilizers (thrives in poor soil), thin runners if overcrowding occurs

3

Flowering

4-6 weeks (late spring to early summer)

Small, nodding, bell-shaped flowers appear at branch tips, typically white with pink tinges, delicately fragrant

Ensure adequate light and air circulation; maintain consistent moisture; do not deadhead if you want berries to form

4

Fruiting & Berry Development

3-4 months (late summer through winter)

Flowers develop into bright red, waxy berries about the size of peas; berries persist through fall and winter

Continue regular watering; berries are attractive to birds and wildlife; do not harvest all berries to allow natural spread

5

Winter Dormancy

3-4 months (late fall through winter)

Foliage remains evergreen and hardy; berries persist and are most vibrant; growth slows significantly

Reduce watering slightly but maintain moisture; no fertilizer needed; plant remains ornamental; protect from harsh wind and extreme cold

Companion Planting

Plan your garden →

Plant with:

Bearberry (Arctostaphylos) Lingonberry (Vaccinium vitis-idaea) Creeping phlox Partridgeberry (Mitchella repens) Lowbush blueberry Ferns Heather (Calluna)

Avoid planting near:

Alkaline-preferring plants (rhododendrons prefer acidic but wintergreen is even more extreme) Plants requiring dry conditions Aggressive spreading groundcovers that compete for space Plants that raise soil pH

Common Pests

  • Increase humidity with misting; spray with water to dislodge; use insecticidal soap if severe

  • Remove by hand; apply horticultural oil in dormant season; prune heavily infested stems

  • Improve air circulation; remove affected leaves; avoid overhead watering; apply fungicide if widespread

  • and

    Increase humidity; spray with neem oil; ensure good drainage to reduce stress

Uses

🍳

Flavoring & Infusions

Culinary

Wintergreen leaves have been traditionally used to create teas, infusions, and flavoring extracts. The distinctive minty, spicy flavor works in desserts, candies, and beverages. [source]

💊

Pain Relief & Anti-inflammatory

Medicinal

Wintergreen contains methyl salicylate (related to aspirin) and has been used traditionally for arthritis, muscle aches, and joint pain. Leaves are steeped into teas or infusions for internal use or made into liniments for topical application. [source]

🏠

Flavoring & Aromatics

Household

Dried leaves are used in potpourri, sachets, and as a natural air freshener. The essential oil provides the distinctive wintergreen scent in cosmetics and personal care products. [source]

🦋

Wildlife Food & Cover

Wildlife

The bright red berries are highly attractive to birds and small mammals, especially in winter when other food sources are scarce. The dense, low growth provides shelter for ground-nesting birds and small creatures. [source]

🎨

Groundcover & Ornamental

Craft

Wintergreen moss creates attractive evergreen groundcover in shade gardens, woodland edges, and acidic landscaping. The combination of glossy foliage, delicate flowers, and persistent berries provides year-round ornamental interest. [source]

Harvest Tips

Leaves can be harvested year-round but are most flavorful in fall. Pinch off young leaves from branch tips for fresh use. For drying, harvest after the first frost when flavor is concentrated. Berries are edible and ready when fully red, typically October through December; harvest by gently rolling them off branches or picking by hand. Both leaves and berries have a distinctive, minty-spicy wintergreen flavor.

Fun Facts

  • 🌱 Wintergreen was the original natural source of wintergreen flavoring and oil before synthetic methyl salicylate became common; a pound of dried leaves yields only about 1-2% essential oil.
  • 🌱 The plant's berries can persist on branches through the entire winter and into spring, providing crucial food for migratory birds and wildlife during harsh months when few other foods are available.
  • 🌱 Native Americans and early colonists used wintergreen extensively for both flavoring and medicine, and the plant is still used to produce natural wintergreen oil used in liniments, toothpaste, and candies today.
