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.
Varieties
[edit]Four varieties of the species are recognized in the Flora of China:[2]
- R. odorata var. odorata, with white or pink-and-white petals
- R. odorata var. gigantea, see Rosa gigantea, with white petals
- R. odorata var. pseudoindica, with yellow or orange petals
- R. odorata var. erubescens, with pale pink petals
Cultivars
[edit]The cultivar R. odorata 'Mutabilis' is widely cultivated, and is notable for the fact that the blooms change colour from yellow to pink. Growing to 1.5 m (4.9 ft) tall and broad, it is a lax, thornless shrub. It prefers an open position in full sun. This cultivar has gained the Royal Horticultural Society's Award of Garden Merit.[3]
Other cultivar names include 'Bengal Crimson'[4][5] and Bengal Beauty.[6][7]
