Constance Spry, arguably the first superstar florist (to the Duke of Windsor, among others), warned that with purple flowers you must consider where they are going. In Flower Decoration (1933), she wrote how beautiful purple flowers are against a “white room...on a pale-green table...against pale yellow brocade,” but put your “purple poppies in a brown room, and all the thrill is gone.” So the white milk jug and colored glass work well, as would a white wedding gown.
