The only flowers on top of the Queen’s coffin during her funeral were a bright wreath of pink, purple, and yellow flowers gifted by the new king, including garden roses and myrtle grown from her own wedding bouquet.

On top of the flowers was a note from King Charles III to his mother that read, “In loving and devoted memory, Charles R.”
