Bilberry

Vaccinium myrtillus

tree

Bilberry (Vaccinium myrtillus) is the wild European blueberry - a low, twiggy, deciduous heath shrub only 8 to 16 in. tall, of cool moors, mountains, and acid pine woods, bearing small, intensely flavored, dark blue-black berries with deep purple flesh. More richly colored and flavored than a cultivated blueberry, the berries (and the leaves) are the prize, gathered in mid to late summer. It demands what all its heath-family kin demand - cool air and very acid, peaty, well-drained soil - and resents heat, so it is a plant for cool climates and carefully acidified ground. Grown for its berries and leaves, it is also a fine, low, fall-coloring groundcover.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Lowbush Blueberry — A fellow low acid-loving heath shrub with identical soil needs, good in a shared acid bed
• Wintergreen — An acid-soil evergreen groundcover that thrives in the same cool, peaty conditions
• Cranberry — Another acid-demanding heath relative for a cool, moist, low planting

• Birds →

  Strip the ripening berries - net the low plants as the fruit colors

• Botrytis (gray mold) →

  Rots fruit and shoots in cool, damp, crowded conditions; give airflow and avoid wetting the berries

• Aphids →

  Cluster on new growth; rinse off and let predators work

🌾 Harvest & storage

Pick the berries in mid to late summer when they are fully dark blue-black, soft, and detach easily; they stain deep purple, so dress accordingly and use a berry comb for the small, low fruit. Eat fresh, or cook into jam and syrup, or dry. Gather the leaves in summer for drying as tea. The berries are delicate and do not keep long fresh, so use, freeze, or dry them promptly after picking.

🥗 Nutrition & benefits

Bilberries are small but intensely flavored and deeply colored, eaten fresh or cooked into superb jams, syrups, pies, and the famous purple bilberry preserves, and dried for winter; the leaves are dried for tea. The dark berries are rich in the same blue-purple antioxidant pigments as blueberries. The plant also makes a pretty, low, fall-coloring groundcover wherever the soil is cool and acid enough to please it.
