Senecio is a large genus of annual or perennial herbs, shrubs, small trees and vines classified within the daisy family.
This softly wooded glabrous (i.e. smooth) shrublet has narrow leaves with margins rolled under. The leaves are sometimes toothed. It bears loose clusters of flower which are carried in a corymb shape, meaning that the inflorescence has the flowers growing in such a way that the outermost are borne on longer stalks than the inner, bringing all flowers up to a common level.
This plant is highly toxic to ruminants and even horses, especially in early spring in degraded veld where they are the first to shoot and there is very little else to eat.
