Quick Facts Pentanema squarrosum, Scientific classification ...

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.[4]
