Rubus glaucus, commonly known as Mora de Castilla or Andean Raspberry, is a type of blackberry found in Latin and South America including the Andes. It has been compared to a loganberry.[1]

It is a perennial semi-erect climbing shrub, belonging to the family Rosaceae . It consists of several round and spiny stems that form the corona of the plant, 1 to 2 cm in diameter, and can grow up to 3 m. The leaves are trifoliate with serrated edges, dark green and white beam beneath. Both stems and leaves are covered by a white powder.

The fruit is a berry ellipsoid of 15 to 25 mm at its widest diameter of 3-5 g weight, green when formed, becoming red when ripe and then dark and bright purple. It consists of small drupe attached to the receptacle when ripe and fleshy whitish rich in vitamin C, calcium and phosphorus, bittersweet, and suitable for juices, nectars, jams, jellies, ice cream, pastries and confectionery. Fruit production is continuous with two annual peaks. Plants reach maturity and produce fruit after the first year extending through the rest of the plant's life which can be 12 to 20 years.

The plant grows best at temperatures between 12 and 19°C, with relative humidity of 80 to 90%, high sunshine and well distributed rainfall between 800 and 2,500mm a year. It is native to tropical highlands of northwestern South America and Central America and prefers elevations between 1,500m and 3,100m. In countries such as Costa Rica it is found in the upper part of the Cordillera de Talamanca and the Central Volcanic Cordillera.
