Thimbleberry is a perennial shrub native to the Upper Peninsula and parts of lower Michigan. It is normally 3 feet in height in the U.P., but may reach 6 feet. This plant tends to spread densely by rhizome, which is great from a food production standpoint. White flowers appear in early summer, followed by edible red berries. Berries are similar to raspberries, but tend to be shorter, wider, softer, and more tart which is  for excellent jam. Birds and mammals also like the fruit. Leaves and bark can also be used for various purposes. Although a member of the rose family, Thimbleberries do not have thorns or pickers.
