The name Florian is a boy's name of Latin origin meaning "flowering". Florian and is often added to lists like Cool, Unique Unisex Names and discussed in our forums with posts like "Which would you choose?".
From the experts:
If Flora and Florence have returned full force, Florian, with its trendy Latinate ending, could also have a chance. Popular in Germany, Austria and Switzerland -- he was the venerated patron saint of those in danger from water and of firefighters -- might sound a tad feminine and floral to English speakers. But as a middle name, Florian could be a great way to honor grandma Florence (or any other flower name).
The second century Roman martyr St. Florian appears in Tennyson's poem "The Princess," and also in Gilbert & Sullivan's comic opera "Princess Ida." Sir Florian Eustace is an off-stage character in Trollope's novel The Eustace Diamonds, Florian Fortescue runs an ice cream shop in Harry Potter, and Florian is the real first name of singer Dido.
