Blueberries

Blueberries are perennial flowering plants with indigo-colored berries that grow on shrubs that can vary in size from 10cm to 4m in height. In the commercial production of blueberries, the smaller species are known as ‘lowbush blueberries’ (also known as ‘wild’), while the larger species are known as ‘highbush blueberries’.

HISTORY

Blueberries are native to North America although many species of blueberries are now grown commercially in the Southern Hemisphere in Australia, New Zealand and South American nations.

The hardy lowbush blueberry plants thrive in Canada and the northern United Staes.

In 1976, the highbush berries began to be cultivated in Ontario.

VARIETIES

Blueberries may be cultivated, or they may be picked from semiwild or wild bushes. In North America, the most common cultivated species is the northern highbush blueberry. Hybrids of this with other blueberry species adapted to southern US climates are known collectively as southern highbush blueberries.

Lowbush (‘wild’) blueberries are smaller than cultivated highbush ones and have an intense colour. The lowbush blueberry, “V. angustifolium”, is found from the Atlantic provinces westward to Quebec and southward to Michigan and West Virginia.
