This biennial is widespread across North America, but generally less common than dubius, which has often been confused. T. pratensis was first reported from Ky. by Greenwell (1935). See Y for notes on variation and nomenclature, which remains uncertain. Hybrids among species of Tragopogon are well documented in western states but virtually unknown in the east; 2n = 12 in all 3 species here (FNA 19).
