"You canker blossom!" 3 Shakespearean Insults
c.1300, lorrer, from Old French laurier (12c.), from Latin laurus "laurel tree," probably related to Greek daphne "laurel" (for change of d- to l- see lachrymose), probably from a pre-IE Mediterranean language. The change of second -r- to -l- after mid-14c. is by dissimilation. An emblem of victory or of distinction, hence the phrase to rest (originally repose) on one's laurels, first attested 1831.
