Derivation of the botanical name:
Carduus, thistle, the classical name.
crispus, curled; curly haired.
  • The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.

It is a favorite foodplant of caterpillars of the Painted Lady, Vanessa cardui [(Linnaeus, 1758) Synonym: Papilio cardui (Linnaeus, 1758)], which derives its specific name from their preference for thistles.
