The scientific name for a rose is Rosa. Roses are a perennial shrub or vine of the Rosa genus and the family Rosaceae. There are more than 100 species of roses, most of which are from Asia.
Roses are classified as deciduous plants divided into a number of categories that depend on breeding and habit. Hybrid tea roses are large flowering shrubs with repeat flowering. Floribunda roses are very similar to hybrid teas, but are more branched. Breeding between crosses of Floribundas and hybrid teas has produced Grandifloras, which are known as large flowered Floribundas. Pruning is very important for most of the rose varieties because it encourages a break in the new buds, which leads to new flower production. Old roses have fragrant flowers, which are recommended for trellising.
The term 'rosa' comes from the Latin word for rose. Some common types of domestic roses include Rosa alba, Rosa centifolia, Rosa damascena and Rosa rugosa. Roses are ornamental plants grown both indoors and outdoors. They have been cultivated for several millennia, with the earliest accounts dating from 500 BC in China, Persia and Mediterranean countries.
