Blueberries are really small- around 0.2-0.6 inches in diameter

In the early 20th century, a smart woman by the name of Elizabeth White, the daughter of a New Jersey farmer thought it fit to grow a flourishing industry for cultivated blueberries.

With the combined effort of a USDA botanist, Frederick Coville, the first commercial crop of blueberries was harvested and sold in 1960.

The most common blueberry variety amongst others is the highbush blueberry- which we see mostly in supermarkets or stores.

And the other variety, lowbush blueberry is smaller and richer in antioxidants. The highbush blueberry grows from a flowering bush.

This bush grows small white flowers that blossom into hard green berries that later ripen in the early summer, becoming blueberries.
