Chimonanthus (wintersweet) is a genus of flowering plants in the family Calycanthaceae, endemic to China. The genus includes three to six species depending on taxonomic interpretation; three are accepted by the Draft Flora of China. The name means winter flower in Greek.
Chimonanthus praecox is widely grown as an ornamental plant for its spicily scented winter flowers; these are also used in floristry as cut flowering branches, which can also be forced as with forsythia. The plant prefers medium exposure to sunlight or partial shadow, fresh climate, and soft, acidic permeable ground. At the end of its flowering, since it flowers most freely on ripened young wood and has little summer and autumn interest, it is thinned by pruning, partly headed back and a few thick old stems removed at the ground,.
