Nargiz is from the Azerbaijani Nərgiz (Nargiz — narcissus / daffodil) — from Persian نرگس (Nargis) — from Greek narkissos. Nargiz is one of the Azerbaijani + Persian feminine names — central to traditional Azerbaijani-Iranian floral heritage.
Nargiz 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 Nargiz reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
