All About Cherry Trees

Yoshinos, the majority species of the blossoms found at the Tidal Basin, provide wildlife value. Their small fruits are un-edible for people, but popular with domestic and migratory songbirds and small mammals, and their flowers provide pollen for bees. An eight inch Kwanzan cherry tree will reduce atmospheric carbon by 201 pounds.
