Carlina acaulis

Carlina acaulis, the stemless carline thistle, dwarf carline thistle, or silver thistle, is a perennial dicotyledonous flowering plant in the family Asteraceae, native to alpine regions of central and southern Europe. The specific name acaulis (Neo-Latin for 'without a stem', from Latin caulis 'stem' or 'stalk') and common names are descriptive of the manner in which its flower head rests directly upon a basal leaf rosette. The plant is named after Charlemagne who searched for a treatment against the plague. He dreamed of an angel who told him to shoot an arrow in the sky and see on what plant the arrow would hit. This plant would bring relieve to the plague. The plant the arrow hit was the Carlina acaulis, the roots of the plant were distributed among the population following which the plague diminished. The spiny, pinnatilobate leaves grow in a basal rosette approximately 20 cm in diameter. The flowers are produced in a large (up to 10 cm) flowerhead of silvery-white ray florets arou......read more on Wikipedia.
