Vegetative characteristics

The Tragopogon species are biennial to perennial herbaceous plants that reach heights of 15 to usually 50 to 150 centimeters. The stems are often branched. The sitting leaves are entire.

Generative characteristics

The flower heads stand individually at the branch ends. They contain 30 to 50 to 180 (or more) ray florets arranged in a row or rarely two rows. In most species, the dark to light brown achenes consist of a fruit-bearing body and a more or less long, thin beak. They develop a large, white to brownish fringe of hair or pappus as a flight parachute. The pappus is between 0.6 and 4 cm long, made of slightly fringed, feathery bristles.


The genus Tragopogon was established by Carl von Linné in Species Plantarum in 1753 . As lectotype was Tragopogon porrifolius L. fixed. The genus Tragopogon belongs to the subtribe Scorzonerinae from the tribe Cichorieae in the subfamily Cichorioideae within the family Asteraceae (Asteraceae).
