Rubus is a genus of flowering plants in the family Rosaceae, comprising hundreds of species. This genus includes raspberries, blackberries, dewberries and wineberries. The blackberris and other Rubus species with the mounding or rambling growth habits are often called brambles. However, raspberries that grow as upright canes, or trailing or prostrate species such as most dewberries, or various low-growing boreal, arctic, or alpine species do not use the name brambles. The genus also includes numerous hybrids, both natural and bred by man, such as Loganberry (Rubus x loganobaccus).
Rubus phoenicolasius (Japanese wineberry or Wineberry) is a species of raspberry in genus Rubus, native to northern China, Japan, and Korea. It is a perennial plant with stems that are densely covered with reddish bristles. In late spring, spikes of purplish red to pink flowers are borne and these are followed by edible, orange or red berries.
Rubus odoratus (Purple-flowering Raspberry, Flowering Raspberry, or Virginia Raspberry) is a species of Rubus, native to eastern North America, from Nova Scotia west to Ontario, and south to Georgia and Alabama. It is a shrub growing to 3 m tall, and unlike most other related species, this plant does not have thorns. The leaves are resembling maple leaves and the flowers are 3-5 cm diameter, with 5 purple petals. The flowers are produced from early spring to early fall, follow these are fruits that mature in late summer to early autumn. The fruit resembles a large, flat raspberry with many drupelets, and is rather fuzzy to the touch and tongue. It is widely grown as an ornamental plant for its conspicuous flowers with a long flowering period. The plant prefers partial shade, rich, slightly acid and well-drained soil.
Rubus fruticosus (Common Blackberry) is an edible fruit produced by any of the several species in the Rubus. In late spring and early summer, spikes of white or pale pink flowers are produced, follow these are black or dark purple berries. The fruit is not a true berry; botanically it is an aggregate fruit of numerous drupelets. The leaves are also food for certain caterpillars and grazing mammals, especially deer, are fond of the leaves.
Some species of Rubus are planted as ornamental plants for their foliage and flowers, and sometimes, attractive winter shoots. some are good groundcover, while others are useful in shady borders or woodland gardens. Birds are attracted to the autmn berries. Rubus species are used as food plants by the larvae of some Lepidoptera species such as Angle Shades, Dot Moth, Double Square-spot, Hebrew Character, and etc.
Plant Rubus in sun or partial shade, in fertile and well-drained soil. Propagation is by division in autumn; greenwood cuttings in summer; and hardwood cuttings in early winter. It is a hardy to frost hardy plant with minimal pests and diseases, except for grey mould which will affect the growth.
