Any of several species of the genus Rubus (family Rosaceae) having fruit consisting of many drupelets attached to a common fleshy, elongated core (receptacle) that is removed with the fruit. Ripe blackberry fruit is usually black or dark purple in color (see illustration) and is often sweet and flavorful. The bushy plants have perennial roots, from which arise long, often thorny, biennial stems (canes) with compound leaves. Many species are native to temperate regions, especially in the Northern Hemisphere, to which they are best adapted. They are commonly found on the edges of forests, along streams and in clearings. Because of their thorns and prolific growth habit, blackberries are a nuisance in some areas. See also: Fruit; Rosales; Weeds
