Blueberries grow on low creeping shrubs or tall erect bushes. The small round berries can range in size from 5-16 millimetres in diameter. They first appear green, but ripen into a deep shade of dusty blue. The soft, hazy white coating that develops on the skins’ surface, which is known as the bloom, is a natural waterproofing which helps protect the berries from the sun and other natural elements. Blueberries have a sweet and woodsy flavour with an acidity that can vary depending upon growing conditions. Long sunny days and warm temperatures develop a higher sugar content, while cooler temperatures and shorter days with limited sunlight increase acidity.
