It is a tall, hairy plant (to 1.2 m) that grows on calcareous, low-nutrient, well-drained soils. It is a short lived perennial plant. Before flowering, the basal rosette of leaves resembles those of foxgloves. It flowers after mid-summer in Europe, from July to September.[3] When in flower, the plant has many small flowerheads grouped together into a flat-topped structure that resembles a single flowerhead (pseudanthium). The individual flowerheads have prominent yellow disc florets and no (or inconspicuous) ray florets.
The leaves are burned and used as an insecticide and parasiticide, especially against fleas. Even the smell of the plant is flea repellent. When the root is burned, it becomes a useful room scent. (Used this way in Turkey)
