Name Game 17

Peaked in the 1940s, but still an amiable classic, a la Joe and Tom -- though rarely used on its own. 

A sweet, nostalgic nosegay kind of name, Posy has been long fashionable in England, a country of gardeners, but this pretty bouquet-of-flowers name is still rarely heard in the US, though it could be seen as a more unusual possible alternative to Rosy or Josie.
 Posy is a little sister name in the Hunger Games series, while before that, Posy Fossil was a character in Noel Streatfeild's Ballet Shoes. In 2026, it appeared on a character in the popular TV series, Bridgerton.
 
For now, Posy is the least popular spelling of the name with Posie first, Posey second, and Posy used for less than ten baby girls in the US in a recent count.
 Posy (or Posey or Posie) could also work as a nickname for a range of other names, from Penelope to Sophia to Primrose, though it started as a pet form of Josephine. Other P-beginning flower names you may want to consider along with Posey: Poppy, Petal, Primrose.
