I discovered these unbelievably white berries on a bush in my back yard. After some research I found out that they are snowberries. The snowberry (Symphoricarpos albus) is a common, native shrub growing in much of North America. Long after the leaves drop off in the autumn the hearty, white berries remain on the branches, serving as a vital source of food for birds, deer and other animals in the winter months. It would NOT be for human consumption!
