More information
Blueberries are small fruits of a shrub tree, which belongs to the heath (Ericaceae) family. Other members of this family include cranberry, bilberry, azalea, mountain laurel and rhododendron. These berries grow in clusters and vary in size from that of the size of a pea, to the size of a marble. The colour often ranges from maroon to purple black. The flesh of the blueberries is semi-transparent and encases tiny seeds. The berries, which are cultivated are mildly sweet, whereas those which grow in the wild are more tart and tangy in flavour. They are round and flattened in shape. They have a crown like structure at the bottom, and a depressed ring at the top of the fruit. Blueberries are usually around 1/2 inch in diameter.
