An edible fruit belong to the Rubus genus in the Rosaceae family, blackberries are native to the temperate Northern Hemisphere and South America. In botanical terminology, blackberries are not a berry per se – rather, they are classified as an aggregate fruit, which is made up of numerous drupelets.
There is concrete evidence that blackberries have been consumed by human beings for thousands of years, making it a fruit that has been eaten since ancient times. The berries are red when they are unripe, and when they ripen, they turn black. In addition to containing plenty of antioxidants, blackberries are also rich in nutrients like anthocyanins, fiber, salicylic acid, and ellagic acid.
A large aggregate fruit of a dark maroon to deep purple colour, boysenberries are a cross between three types of berries – a Common Blackberry (Rubus fruticosus), the European Raspberry (Rubus idaeus), and a Loganberry (Rubus × loganobaccus).
An abandoned experiment by a man named Rudolph Boysen, the boysenberry plant was rescued by George M. Darrow and Walter Knott, nurtured back to health, and then marketed with great success. The berry is rich in antioxidants, Vitamin C, fiber, and ellagic acid which fight cancer, viruses and bacteria.
