Q.A flower
I remember reading about a flower that grew wild along the roads in England. It was called Gladwins, but I cannot find any such flower listed anywhere. Do you know of any such flower?
I hope this is what you are looking for: Stinking iris, aka gladdon, gladwin and others. A perennial with glossy, rich green leaves and small, yellow-tinged, purple flowers followed by large pods opening to show bright orange-red seeds, persisting into winter. Height and spread 40cm (16in). (from RHS.org)
