The Bramble belongs to the Rosaceae family, Rubus genus, fruticosus species. Other species are R. laciniatus, R. procerus and R. ulmifolius, all widespread in Europe and Italy, and R. canadensis, bearer of the thornless character, widespread in North America. It is a shrub with very long shoots (even 3 meters) and a high polloniferous capacity.
The pinkish-white flowers are gathered in paniculate or corimbiform terminal inflorescences. The fruit consists of berries gathered in dark and bright purple blackberries.
Alla tells the receptacle remains adherent to the fruit. Pollination is entomophilic. both unarmed and thorny cultivars are grown.
Rustic, resistant to winter colds and late frost.

Among the varieties of general interest, which derive from species of American origin, we mention the Thornfree, the Black Satin, the Dirksen Thornless and the Hull Thornless.
Adaptable to all environments, however, it enhances the production capacity in deep and fertile soils. In protected cultivation, unheated tunnels, it anticipates the start of the harvest in July by checking the best prices on the fresh market. It requires piling, green pruning to reduce the number of renewal shoots and, before ripening, to trim the females. With winter pruning, the old shoots are eliminated, the 4-5 new shoots appear at 2 m from the ground, cleaning them from the up to 40 cm and shortening the others to 3-4 buds, and they are tied to the fan-shaped threads.
The harvest starts in July and lasts until September. The yield per hectare is greater than 100 quintals.
The intense and pleasant aroma and the bright black color make the blackberry a precious ingredient for many safe preparations (jams, syrups). some varieties are particularly suitable for fresh consumption, even without the addition of sugar.
The climatic adversities are represented by winter and autumn frosts and late frost, as well as excessive winds and intense rains during flowering.
The most harmful viroses and mycoplasmosis are the Mosaic and the Dwarfism (transmitted by a cicadellide).
The most harmful animal parasites are the raspberry and bramble antonomus and the yellow mite.
