plant of Eurasia, cultivated for its medicinal root, late 14c., from Old French valeriane "wild valerian" (13c.), apparently from feminine singular of Latin adjective Valerianus, from the personal name Valerius (see Valerie); but Weekley writes, "some of the German and Scand. forms of the name point rather to connection with the saga-hero Wieland."
