"artichoke-like plant of the Mediterranean lands," 1610s, from French cardon, from Provençal cardon, properly "thistle," from Late Latin cardonem (nominative cardo) "thistle," related to Latin carduus "thistle, artichoke," which is perhaps from PIE root *kars- "to scrape, scratch" (see harsh (adj.)).
