The name Bryony is a girl's name of Latin origin meaning "to sprout". Bryony and is often added to lists like Flower Names for Girls and discussed in our forums with posts like "DROP 2, ADD 1 (Girls!!!)".
From the experts:
Bryony is an unusually strong plant name --the bryony is a wild climbing vine with green flowers --that caught on in the U.K. before sprouting here. The name of the young character in the Ian McEwan novel Atonement is spelled Briony, which is the variation and Bryony the original.
Bryony sounds a lot fresher than the now dated Brittany. Pronunciation is like Brian with an ee at the end, though the name bears no relationship to the male Brian or Bryan.
