Notes: Germinates in autumn; may remain as a rosette over the first summer. Weed of pasture, particularly fertile soils, extending over much of non-arid south eastern Australia. Plants may form dense stands that smother other pasture species and decrease pasture production. Most of the tall Onopordum seen in Australia are hybrids with a full range of genetic intermediates between Scotch Thistle and Illyrian thistle, Onopordum illyricum and with some genes for species not recorded from Australia. Bract width around heads particularly reflects this variation.
