Blueberries are perennial flowering plants with blue or purple berries. They are classified in the section Cyanococcus within the genus Vaccinium. Vaccinium also includes cranberries, bilberries, huckleberries and Madeira blueberries.
Blueberries are popular in home gardens because they can grow in a small space, even in containers. In fact, they are one of the easiest berries to grow. There are three main types of blueberries: highbush, rabbiteye, and southern highbush. Blueberries are a large species of flowering and fruiting shrubs that are native to North America. Cultivated blueberries are continually being bred for higher yields, heat and cold tolerance and better pest resistance. Still, some people prefer the blueberries that grow wild in forests and fields. Wild berries are smaller, and it will take you a while to pick enough for a pie, but many people find them the sweetest to eat.
