Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The flower heads are normally rayed, completely yellow, and the heads are borne in branched clusters. Senecio is one of the largest genera of flowering plants, and despite the separation of many species into other genera it still contains over 1000 species of varied form, including leaf, stem and tuber succulents, annuals, perennials, aquatics, climbers, shrubs and small trees. Some species produce natural biocides (especially alkaloids) to deter or even kill animals that would eat them.

Senecio medley-woodii, also known as Caputia medley-woodii, is a beautiful South African indigenous succulent that bears awesome yellow flowers during winter. This South African endemic beauty will add bright splashes of winter colour to any rock garden or container. The leaves are white-felted and when it receives sufficient sunlight the edges turn a beautiful deep red. This plant is easily propagated from seed and very easy in cultivation.
