Calycanthus chinensis, known as Chinese sweetshrub, is a species of flowering plant in the family Calycanthaceae, native to Southeast China. It was first given a valid scientific name in 1964. It is cultivated as an ornamental flowering shrub, and has been hybridized with two other species in the genus Calycanthus to combine its larger and broader tepalled flowers with their scented and more colourful ones.
It has been treated as the only species in the genus Sinocalycanthus.
Calycanthus chinensis is cultivated as an ornamental shrub. In the United States, it is usually considered hardy in zones 6–8. In Europe, it is hardy as far north as eastern Scotland. Well-drained but moist, acid soils are recommended. In cooler climates, full sun is recommended, and it will have a long flowering season, beginning in June in southern England. In warmer climates in the US, it will grow in some shade and has a shorter but earlier flowering season, beginning in April. It can be propagated by softwood cuttings in summer, or by seed.
Calycanthus chinensis is known from Zhejiang Province in southeastern China, where it is found at elevations of 600–1,000 m (1,970–3,280 ft) in woods, particularly along streams.
