Gaultheria procumbens, commonly called wintergreen or checkerberry, is a charming creeping evergreen groundcover native to North American forests. This low-growing herbaceous plant produces delicate white to pink flowers in spring, followed by brilliant scarlet berries in autumn. Highly ornamental and remarkably hardy, it thrives in acidic, moist soils and partial shade, making it an excellent choice for woodland gardens, shaded borders, and forest floor displays.
The gardener's calendar
Ideal time to plant wintergreen: set it out when the soil is neither frozen nor waterlogged, and water generously as it establishes.

Expert tips
The key tip
Plant in acidic, humus-rich soil. It spreads in a dense mat: excellent groundcover.
The common mistake
Planting it in neutral or chalky soil: it yellows and slowly deteriorates, unable to absorb the iron it needs.
The pro's trick
Pick young leaves in May-June: they have a delicious peppery flavor in tea or salads.
Care
Light
Wintergreen prefers partial to dappled shade, ideally beneath a forest canopy or in a north or north-east facing position. It tolerates a few hours of gentle morning sun but dislikes the intense afternoon heat that can scorch its leaves. Heavy shade will slow fruiting production.
Watering
Keep the soil consistently moist but never waterlogged. Regular watering is essential during spring and summer growth periods. Increase watering frequency during dry spells to ensure the substrate never fully dries out. Autumn and winter require less water, but never allow the soil to dry completely.
Soil
This acid-loving plant demands acidic soil (pH 4.5 to 6), rich in organic matter and well-draining. Incorporate leaf compost, peat moss, or ericaceous soil at planting time. A mulch of fallen leaves or pine needles maintains soil acidity and moisture.
Feeding
A spring application of fertilizer formulated for acid-loving plants is usually sufficient. Excessive nitrogen promotes foliage at the expense of fruiting. Choose a balanced fertilizer or one slightly lower in nitrogen.
Pruning
No pruning is necessary for the wild plant. You can lightly clean up after winter by removing dead stems. If you wish to limit its spread as a groundcover, trim the shoot tips in early spring to encourage a denser habit.
Diseases and pests
This hardy plant resists disease well when soil is properly drained. Powdery mildew may appear in conditions of stagnant moisture. Watch for spider mites in overly dry conditions. Moist, well-aerated soil prevents most fungal issues.
Did you know?
Wintergreen produces tiny brilliant scarlet berries in autumn, once eaten by Native Americans who called it 'spicebush' for its pungent and invigorating taste. When you crush its leaves, they release a characteristic mint and wintergreen fragrance that made it a traditional remedy for rheumatism.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
