Blackberry fruit, originated in North America, began in ancient Greece more than a thousand years ago. Local people have formed the custom of eating wild thorny blackberries. Recognized by FAO as the third generation of new special fruit, it is praised as "fruit of life" and "black diamond" by European and American countries because of its rich nutrition.

BlackBerry is mainly distributed in North America, Europe and other places, with more than 70 varieties worldwide. It can be divided into three types: trailing, semi erect and erect shrubs, with or without thorns, and three fruit types: long ball, cylindrical or conical. BlackBerry has high requirements for land and environment, moderate moisture and fertility, and high-quality varieties can adapt to barren land.
