Blackberries are considered to be bramble fruits, which means that they come from thorny plants which belong to the genus “Rubus” which is in the rose family or Roseaceae. A bramble fruit is any fruit that has thorns and comes from this genus, including blackberries and raspberries. Both of these fruits have quite a bit in common, including the genus they come from.

Many people have the misunderstanding that blackberries are actually vegetables; however they are in fact categorized as fruits because of the genus they belong to as well as other defining characteristics which make them fruits and not vegetables.
