It has become naturalized in a few places, such as California in the United States and Baja California in Mexico.[4][4][5]Sonchus tenerrimus is an annual or perennial herb producing a slender, branching stem up to about 80 centimeters (32 inches) tall. The leaves are deeply divided into many variously-shaped lobes which may have toothed edges or smaller lobes. The inflorescence bears flower heads lined with glandular, hairy to woolly phyllaries. They are filled with numerous yellow ray florets but no disc florets. The fruit is an achene up to a centimeter long including its pappus.[6]References1. ^The Plant List, Sonchus tenerrimus L. 2. ^{{PLANTS|id=SOTE3|taxon=Sonchus tenerrimus|accessdate=19 November 2015}} 3. ^Altervista Flora Italiana, Sonchus tenerrimus L. includes photos and European distribution map 4. ^Shreve, F. & I.
