Rosa × odorata

(Redirected from Rosa odorata)

Rosa × odorata or Rosa odorata is a hybrid flowering plant of the genus Rosa native to Yunnan in southwest China, whose taxonomy has been confused. It has been considered a hybrid of Rosa gigantea and Rosa chinensis, or as a quite rare wild species that includes R. gigantea. The wild forms are cultivated to some extent.[2] Cultivars were developed in China in ancient times from R. chinensis crosses, and these have been important in the ancestry of the tea-scented China roses, also called tea roses, and their descendants the hybrid tea roses.
