Morus nigra

Morus nigra, called black mulberry or blackberry, is a species of flowering plant in the family Moraceae that is native to southwestern Asia and the Iberian Peninsula, where it has been cultivated for so long that its precise natural range is unknown. The black mulberry is known for its large number of chromosomes, 308.Sometimes other mulberry species are confused with black mulberry, particularly black-fruited individuals of the white mulberry. Black mulberry may be distinguished from the other species by the uniformly hairy lower surface of its leaves. Mulberry fruit color derives from anthocyanins.
