About

Vaccinium ( vak-SIN-ee-əm) is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other heath plants, they are restricted to acidic soils.

How to grow it

Blueberries (sect. Cyanococcus) and cranberries (sect. Oxycoccus) are relatively newly cultivated plants and are largely unchanged from their wild relatives. Genetic breeding of blueberries began around the turn of the 20th century. It was spearheaded by Frederick Coville, who performed many cross-breeding trials and produced dozens of new blueberry cultivars. He often tested new cultivars for their flavor, claiming after a long day of tasting that "all blueberries taste the same, and all taste sour."

Where it grows

The genus contains about 450 species, which are found mostly in the cooler areas of the Northern Hemisphere. However, there are tropical species from areas as widely separated as Madagascar and Hawaii. The genus is distributed worldwide except for Australia and Antarctica, but areas of great Vaccinium diversity include the montane regions of North and South America, as well as Southeast Asia. Species are still being discovered in the Andes.
