''Rosa chinensis'' (Chinese name: 月季, pinyin: yueji), known commonly as the China Rose or Chinese rose, is a member of the genus ''Rosa'' native to Southwest China in Guizhou, Hubei, and Sichuan Provinces. The species is extensively cultivated as an ornamental plant, originally in China, and numerous cultivars have been selected which are known as the China roses. It has also been extensively interbred with ''Rosa gigantea'' to produce ''Rosa × odorata'', and by further hybridization the Tea roses and Hybrid Tea roses. It is a shrub growing to 1–2 m tall. The leaves are pinnate, have 3-5 leaflets, each leaflet 2.5–6 cm long and 1–3 cm broad. In the wild species (sometimes listed as ''Rosa chinensis'' var. ''spontanea''), the flowers have five pink to red petals. The fruit is a red hip 1–2 cm diameter. ==Varieties== Three varieties of the species are recognized in the ''Flora of China'':〔(Flora of China: ''Rosa chinensis'' )〕 * ''R. chinensis'' var. ''chinensis'', originated in cultivation, with red petals * ''R. chinensis'' var. ''spontanea'', native to Guizhou, Hubei, and Sichuan, with red petals * ''R. chinensis'' var.
