More than 24 species of blackberry are known, including several called dewberry and albino varieties called white blackberry. One of the most common species is the sow-teat blackberry ...
Scientific classification: Blackberries belong to the genus Rubus of the family Rosaceae. The sow-teat blackberry is classified as Rubus allegheniensis.
