Flowering
April-May (4-6 weeks)Delicate pink or white urn-shaped flowers appear in late spring, clustered in short racemes along branches
Ensure adequate moisture to support flower development, avoid pruning during flowering, maintain mulch layer, pollinate by hand if bees are sparse
Fruiting
June-August (8-10 weeks)Small green berries develop and gradually ripen to deep blue-black color with a silvery-gray bloom coating
Maintain consistent watering, protect from birds with netting, do not fertilize during fruiting, monitor for pest damage

Harvest Tips
Berries ripen gradually from July through August; harvest when fully dark blue and easily detach with a gentle twist. Ripe berries have a slightly wrinkled appearance. Pick frequently to encourage continued production. Berries do not ripen further after picking. Fresh berries are delicate and bruise easily; use shallow containers. Yield per mature plant is typically 1-3 pounds.
Fun Facts
- 🌱 Myrtle blueberries were used by RAF pilots during World War II who were given bilberry jam to eat before night bombing raids, based on folk claims it improved night vision—a practice that sparked modern research into anthocyanins and vision health.
- 🌱 The plant is called 'bilberry' in British English, 'whortleberry' in some dialects, and 'blueberry' in American usage, though it is botanically distinct from the American highbush blueberry (Vaccinium corymbosum).
- 🌱 In European folklore, bilberry was considered a 'fairy fruit,' and picking it in certain locations was believed to be protected by fairy magic; the berries have been foraged from wild woodlands for centuries across Europe and Scandinavia.
