etiolate (v.)
"turn (a plant) white by growing it in darkness," 1791, from French étiolé, past participle of étioler "to blanch" (17c.), perhaps literally "to become like straw," from Norman dialect étule "a stalk," Old French esteule "straw, field of stubble," from Latin stipula "straw" (see stipule).
