Senecio is a large genus with over 1,400 individual species found across the globe. These include annual plants, succulents and non-succulent perennials, evergreen shrubs, subshrubs and twining climbing species. They are typically grown for their attractive but highly variable foliage and their daisy-like flowers, which are produced in branched clusters. Annuals are best used for bedding or in containers, while small perennials look great in a scree bed or rock garden. Taller species are best suited in a border or wild garden. The genus includes many species commonly kept as houseplants, such as Senecio rowleyanus, commonly known as String of Pearls.
