Bluma comes from the Yiddish blum, meaning "flower" — sharing a root with the German Blume.
Bluma is widely used in Hasidic communities.
Bluma 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 Bluma reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
