Canadian blueberry, Vaccinium myrtilloides, is also called common blueberry, velvetleaf huckleberry, velvetleaf blueberry, and sourtop blueberry. It is a species of blueberry native to North America. It has been reported from every Canadian province plus the Northwest Territories, as well as from the northeastern and Great Lakes states in the United States. It is also known to occur in Montana. 
Vaccinium myrtilloides is a low spreading deciduous shrub growing to 50 cm tall, often in small thickets. The leaves are bright green, paler underneath with velvety hairs. The flowers are white, bell-shaped, 5 mm long. The fruit is a small sweet bright blue to dark blue berry. Young stems have stiff dense bristly hairs. 
This plant grows best in open coniferous woods with dry loose acidic soils; it is also found in forested bogs and rocky areas. It is fire-tolerant and is often abundant following forest fires or clear-cut logging. Vaccinium myrtilloides hybridizes in the wild with Vaccinium angustifolium - lowbush blueberry.
