As a given name, Daisy refers to the white flower; the word itself is ultimately derived from the Old English word dægeseage, meaning "day eye". It was first used as a given name in the 19th century, when many other plant and flower names also came into common use. It is sometimes used as a nickname for the names Margaret or Marguerite, as marguerite means Daisy in French. It has risen in popularity in modern times, especially since the early 2000s.
