Blueberries
National Blueberry Day is today! Two types of blueberries exist, lowbush (wild) and highbush (cultivated). Most American blueberries are highbush. Oregon produces more blueberries than any other state, followed by Washington, Georgia, and Michigan. The blueberry is considered a superfood because it contains anthocyanin, an antioxidant. The fruit can served in a variety of ways, from just grab-a-handful to blueberry pie to blueberry muffins to blueberry jam. Children can learn more at: Blueberries.
