<Li> × Hulthemosa Juz . (Hulthemia × Rosa) </Li> <P> A rose is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae, or the flower it bears .

Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds . Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa . Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant . Roses have acquired cultural significance in many societies . Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height . Different species hybridize easily, and this has been used in the development of the wide range of garden roses . </P> <P> The name rose comes from French, itself from Latin rosa, which was perhaps borrowed from Oscan, from Greek ρόδον rhódon (Aeolic βρόδον wródon), itself borrowed from Old Persian wrd - (wurdi), related to Avestan varəδa, Sogdian ward, Parthian wâr . </P> <P> The leaves are borne alternately on the stem .
