The term 'Flowering Thistlelike Plant' is referring to the plant known as Teasel (6 letters). Teasel is a biennial flowering plant in the genus Dipsacus, native to Europe, Asia and North Africa. It has been introduced to other parts of the world, including North America, where it is now considered an invasive species. The plant has spiny, thistle-like leaves and produces large, purple flower heads. It is often used in gardens as an ornamental plant and for its medicinal properties.
