Argemone mexicana (Mexican poppy, Mexican prickly poppy, Flowering
thistle, cardo or cardosanto) is a species of poppy found in Mexico and
now widely naturalized in many parts of the world. An extremely hardy
pioneer plant, it is tolerant of drought and poor soil, often being the
only cover on new road cuttings or verges. I found these in Barisal
Maha-Shamshan.
