Cultivation DetailsSucceeds in most soils. Requires a warm sheltered position in full sun or light shade in a well-drained moisture retentive moderately fertile soil. Rich soils discourage flowering by encouraging excessive growth. This species is not very hardy in Britain, succeeding outdoors only in the mildest areas of the country and even then usually requiring the protection of a wall[166, 182]. Plants can tolerate temperatures down to about -10°c if the wood has been thoroughly ripened. A very ornamental plant, the flowers are sweetly fragrant emitting a honey-like aroma. This species is the state flower of South Carolina. A climbing plant, supporting itself by twining around other plants and often ascending to the tops of lofty trees in its native habitat.
