The early American colonists made grey paint by boiling blueberries in milk.
The blue paint used to paint woodwork in Shaker houses was made from sage blossoms, indigo and blueberry skins, mixed in milk.
If all the blueberries grown in North America in one year were spread out in a single layer, they would cover a four-lane highway that stretched from New York to Chicago.

Blueberries and huckleberries although related, are not the same. One obvious difference is that the blueberry has many soft, tiny almost unnoticeable seeds, while the huckleberry has ten larger, hard seeds. Blueberries are also more blue, while huckleberries are blackish blue or redish black. This red/black variety is also called southern cranberry.
Blueberries have been commercially cultivated only since the early 20th century.
Blueberries contain significant quantities of both antibacterial and antiviral compounds, and have a reputation in northern Europe of fighting infections. They may also help protect against heart disease.
The blueberry muffin is the official muffin of Minnesota.
The blueberry is the official berry of Nova Scotia.
