Floriana is the Italian feminine of Florian — from the Latin flos (flower), meaning "flowering" or "blossoming." Saint Floriana was an early Christian martyr.
Floriana is widely used in Italy and Malta.
Floriana 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 Floriana reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
