|Blackberry flower, Rubus fruticosus species aggregate|
Rubus (formerly Eubatus)
The blackberry is an edible fruit produced by many species in the genus Rubus in the family Rosaceae, hybrids among these species within the subgenus Rubus, and hybrids between the subgenera Rubus and Idaeobatus. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus Rubus has been called the Rubus fruticosus aggregate, although the species R. fruticosus is considered a synonym of R. plicatus.
Rubus armeniacus ("Himalayan" blackberry) is considered a noxious weed and invasive species in many regions of the Pacific Northwest of Canada and the United States where it grows out of control in urban and suburban parks and woodlands.
From Middle English blakberie, blakeberie (“brambleberry”), from Old English blacu berġe, blæcberġe (attested in plural blaca berġan, equivalent to black + berry.
