Serratula consists of perennial species characterized by their serrated leaves, which are not spiny. The plants produce heads of flowers that resemble knapweed, typically in shades of purple. These flower heads are surrounded by multiple overlapping involucral bracts, which are often brownish and have a chaffy texture.
