JUNE BERRY, or Service Berry
the edible purple fruit of the Shad Bush, a small tree found in several varieties in many parts of North America. The "Service Berry" is of peculiar interest in the West, for it often formed the sole food of the Mormons and other pioneers in their days of hardships and privations. It is also known as the "Bilberry" in some sections.
The name Service Berry is occasionally applied also to the edible fruit of several shrubs and trees of the Mountain Ash family, the berries resembling tiny apples.
