Blackberry is a native species and the berries give way to black seeds. The fruit is most often eaten with sugar, wine jelly, cream, or yogurt.
Fruit growers will place them in temperate climates, such as in southern France or Valencia respectively for forcing for market use. They are often one of the final varieties to be ripened so they retain their firmness and do not rot on the stem.
Blackberries grow abundantly along streambeds throughout much of Oregon but are also cultivated commercially in many other countries around the world because of their popularity.
