The Calycanthus family, also known as the sweetshrub family, is a group of flowering plants that includes four genera: Calycanthus, Chimonanthus, Idiospermum, and Sinocalycanthus. The sweetshrub family is distinguished by their fragrant flowers and their use in traditional medicinal practices. Other synonyms for the Calycanthus family include the Spicebush family, which refers to the genus Calycanthus specifically, and the Allspice family, due to the plants' similar aroma to the popular baking spice. Members of the Calycanthus family are typically grown in gardens for their ornamental qualities and their hardiness in colder climates.
