Cirsium spinosissimum , common name Spiniest Thistle, is a European species of thistle which grows in dry rocky areas. It is found in France, Italy, Germany, Switzerland, Austria, and the Balkans.^[2]

The plant is between 20 to 80 cm (8-32 inches) tall. Leaves, stems, and the sides of the flower head bear long, sharp spines, hence the name of the plant. Flower heads contain numerous disc florets but no ray florets, the florets off-white sometimes with a purple tinge.^[2]
