Poppy is the English word for the bright red wildflower — papaver rhoeas in Latin. The poppy has carried multiple symbolic meanings across cultures: in Greek mythology associated with Demeter and sleep; in the modern era a symbol of remembrance for the war dead following World War I.
Poppy entered the U.S. top 1000 in 2016 and has been rising rapidly. In the United Kingdom it has been in the top 30 for years. Today it sits in the U.S. top 350 — a small, bright, contemporary name.
Poppy does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Poppy reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
