It is a small shrub about 50 / 60cm tall with oval or lanceolate leaves with a serrated edge and bright green or gold-yellow during the autumn season. During the final part of the spring season, the blueberry plant has the particular characteristic of producing bunches of flowers with a typically bell-shaped shape and extremely small dimensions, which are characterized by having a white color and developing at the leaf axil. During the initial phase of the summer or autumn season, the typically round fruits come to maturity. The fruits of the blueberry are characterized, in the first place, to have a traditional purple color and, in most cases, they are covered with powder, which guarantees a good opacity.
