Flowering Raspberry (Rubus Odoratus)
The generic name is derived from the Latin word ruber, meaning red, referring to the colour of the fruit. It is estimated that the genus contains as many as 400 species but this must be considered as approximate because they interbreed freely in the wild, producing many natural hybrids, the systematic classification of which is uncertain. Brambles are small shrubs, semi-shrubs or herbaceous plants, some deciduous, others evergreen, some even perennial. The stems are frequently prostrate or creeping, sometimes spiny. The leaves are alternate, simple or more often palmately compound to trifoliate and thehave five sepals and five petals. The ovaries ripen into clusters of small drupes joined on a common receptacle to form the well-known raspberry-type fruit.
Rubus odoratus is a native of North America and was first introduced into Europe (France) in 1635. It is a 2 to 3m (6 to 10ft) high shrub with leaves measuring up to 25cm (10 in) and fragrant, purple flowers appearing in July till August. The berries are red. Rosa odoratus alba has white flowers. Propagation can be by means of seeds which germinate in the first year or by division and root cuttings, as well as by summer cuttings. It is well suited for large parks, requiring good, moist and humusy, and tolerates shade, doing well under trees.
