Senecio is a large genus of plants within the daisy family, comprising over 1,000 species dispersed around the world, ranging from noxious weeds to highly prized garden perennials. Dusty Miller (S. cineraria) for example, belongs to this genus. Within the genus are included about 100 succulent species used as garden plants in warmer climates and as container-grown plants in other regions. Nearly all Senecio species should be considered toxic to animals. Some are large shrub varieties, but many are trailing plants used as spreading ground covers or in hanging baskets. There are also simple upright species.
