 Anthocyanins temporarily color the edges of some of the very young leaves as they unfold from the buds in early spring.They also give the familiar color to such common fruits as cranberries, red apples, blueberries, cherries, strawberries, and plums.Anthocyanins are present in about 10% of tree species in temperate regions, although in certain areas — most famously northern New England — up to 70% of tree species may produce the pigment.
