A rose is a perennial flower shrub or vine of the genus
Rosa, within the family Rosaceae, that contains over 100 species
and comes in a variety of colours. The species form a group
of erect shrubs, and climbing or trailing plants, with stems
that are often armed with sharp prickles. Most are native
to Asia, with smaller numbers of species native to Europe,
North America, and northwest Africa. Natives, cultivars and
hybrids are all widely grown for their beauty and fragrance.
