Thick Leaf Rubus
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.

== Description ==
What distinguishes the blackberry from its raspberry relatives is whether or not the torus (receptacle or stem) “picks with” (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit.

The term bramble, a word referring to any impenetrable thicket, has in some circles traditionally been applied specifically to the blackberry or its products, though in the United States it applies to all members of the genus Rubus. In small parts of the western US, the term caneberry is used to refer to blackberries and raspberries as a group rather than the term bramble. Briar or brier is also sometimes used to refer to the plant, though this name is used for other thorny thickets (such as Smilax) as well.
The usually black fruit is not a berry in the botanical sense of the word.
