Some varieties of Serviceberry, more commonly known as Shadbush up here because it blooms  during the Shad run, grow in most parts of the US and southern Canada. Some grow as shrubs, some as small trees. If you spend any time tramping outdoors, you will see them.

Some varieties are used as landscape plantings (I have used them) but most grow wild, especially in brushy edges. 

The berries look somewhat like blueberries, and range from red to purple to black. 

Depending on the variety, the berries can be sour or sweet. All are edible raw, and you can make jam with them too.

Serviceberry is not to be confused with the Huckleberry, also a common wild plant. Huckleberry is a common meadow edge plant.
