The Language of Flowers
"The Language of Flowers" is an unpublished song from a poem by the American poet and botanist James Gates Percival, with music written by the English composer Edward Elgar, when he was only fourteen years old.
It is dated 29 May 1872, inscribed "by Edward W. Elgar", with "words by Percival" (at first thought to be Elgar himself) and dedicated "to my sister Lucy on her birthday."
