small, hand-held bouquet popular in mid- 19th-century Victorian England as an accessory carried by fashionable ladies. Composed of mixed flowers and herbs and edged with a paper frill or greens, the arrangement was sometimes inserted into a silver filigree holder. When supplied by an admirer, a nosegay became a vehicle for the floral "language of love"-e.g., a red tulip was a declaration of love; a sprig of dogwood returned by the young lady was a sign of indifference; a variegated pink meant that she rejected her suitor's affection. This variety of bouquet has enjoyed periodic revivals.
