Outsidepride Blueberry Fruit Plant Vaccinium Myrtillus Seed - 2000 Seeds Blueberry plants grow as a perennial in USDA Zones: 3 - 8 and thrive in full sun and acidic soil. Vaccinium Myrtillus shrubs will reach 12 inches in height and start producing berries when they are about 2 years old. In order for blueberry plants to produce berries the soil pH needs to be between 4.5 - 5.0 and during the growing season, they typically require 1 inch of water per week. Sow these heirloom seeds at 2 - 3 seeds per plant in well-drained and keep moist until germination occurs in 8 - 12 weeks. Our seeds are always Non-GMO and packaged for the current year.
