Posie is a spelling of Posy, the English word for a "small bouquet of flowers", which itself comes from poesy, because a posy once meant a short verse engraved on a ring. In England it has long served as a nickname for Josephine, and it fits the fashion for sweet vintage names like Poppy and Pippa. Posie had fewer than five births in 2000, rose sharply at the end of the 2010s, peaked at number 2207 in 2021 and ranks number 2679 in 2025 with 65 girls.
