[Wikipedia] Europe & North Africa native, Troublesome weed: Helminthotheca echioides, known as bristly (or prickly) oxtongue, is a sprawling annual or biennial herb native to Europe and North Africa. It was originally placed within the genus Picris but is often separated within the small genus Helminthotheca alongside a few other (mainly North African) plants which also have the distinctive outer row of bracts around the flowerheads. It is a ruderal plant, found on waste ground and agricultural soils around the world, and in some places it is considered a troublesome weed. (link added by Mary Ann Machi)
