Blackberries are semi-deciduous, scrambling shrubs with tangled, prickly stems that form impenetrable thickets several metres high. 

Each berry can contain from 20 to 30 seeds. At the end of the blackberry season, there may be up to 13,000 seeds/m2 under a blackberry bush. Plants in dense shade will produce fewer seeds than those in open areas. Seedling survival rate is also considerably lower in shaded areas compared to areas with full sun.

The root system is the perennial part of the plant. It comprises a woody crown that can grow up to 20 cm wide with a main root that can grow to a depth of 4 m. Secondary roots grow horizontally from the crown for 30-60 cm, then grow down and shoot thin roots in all directions.Stems are known as canes and can grow up to 7 m long.

They can be erect, semi-erect, arching or trailing. With the exception of R. ulmifolius var. anoplothyrsus, the canes are covered in sharp prickles. Canes generally live for two years (biennial) but may live for longer. They may be green, purplish or red depending on their exposure to light. The first year canes (primocanes) root where they touch the ground, producing a daughter plant. In their second year, primocanes form buds which sprout in spring to produce short canes (floricanes) that terminate in a branched cluster (panicle) of flowers and fruit.Leaves generally occur alternately along canes, are compound (with three to five leaflets), and are dark green on top with a lighter green underside. L

eaflet veins and stalks are covered with short, curved prickles. Most leaves shed from the canes during winter except in warmer climates.

White or pink flowers 2-3 cm in diameter occur at the end of floricanes from late November to late February. Clusters of flowers are either cylinder or pyramid-shaped, and may change colour between budding and opening depending on the species. Blackberry is is mostly restricted to areas with temperate climates (warm summers, cool winters) with an annual rainfall of at least 700 mm (regardless of altitude), but plants can grow in lower rainfall areas when other environmental conditions are favourable (such as along the banks of watercourses).

Blackberries are also a good source of amino acids and essential dietary fiber without offering any harmful cholesterol.
Benefits of blackberry which provides respite in various health conditions have been discussed as under:


Antioxidant potential: Blackberries contain a profuse amount of powerful antioxidant which protects the body in multiple ways. Components such as phenolic acids, flavonoids and flavonols particularly anthocyanosides present in blackberries work against the harmful oxygen free molecules and counteract their action.

Anti-cancer properties: Blackberry fruit is effective against the development of cancer including lung cancer, colon cancer and esophageal cancer. The micronutrients present in blackberries exert chemopreventive effect and prevents the proliferation of malignant cells. Various scientific research conducted on blackberries have advocated this fact and have attributed the anti-cancer activity to the abundance of anthocyanins and other phytochemicals such as ellagic acid and cyaniding-3-glucoside which inhibits tumor growth and metastasis.Defense against endothelial dysfunction: Blackberries provides protection against the endothelial dysfunction which is characterized by the abnormal functioning of inner lining of blood vessels. As suggested by scientific studies, it contains useful components such as cyaniding-3-O-glucoside which fights the oxidative activity and helps in the normalizing multiple critical factors implicated in such conditions. It helps in reducing the DNA damage and guards against vascular failure.blackberryinfoCognitive benefits: Blackberry also extends its beneficial effect in improving the cognitive functions of the body. Research studies have suggested that polyphenolic components present in blackberries help retard the age-related decline in motor and cognitive activity attributing to their super antioxidant power. Regular consumption of blackberry may prove useful in enhancing the memory performance and improves behavioral and neuronal functions.Improved digestive health: Blackberries are a source of both insoluble and soluble fiber essential for the optimum functioning of digestive system.

Regular consumption of blackberries helps in protecting the eyes from ultraviolet radiations attributing to the presence of lutein. Lutein forms protective pigment in the area behind the retina, also known as macula and prevents it from the damage caused by oxidative stress and high wavelength light radiations. Furthermore, anthocyanosides and vitamin content present in blackberries enhances the vision and protect the eyes from various diseases such as macular degeneration, cataract and night blindness.Normal blood clotting: Blackberries contains good amount of vitamin K which helps in normal clotting of blood. It helps in preventing excessive bleeding from even slight injuries and aids in healing wounds.
