Daffodil

Yes, though it seems so extreme, girls were actually sometimes given this name a century ago; now it is so uncommon it would make a strong springtime statement. Biggest obstacle: the nickname Daffy.

The daffodil is the national flower of Wales, and in the language of flowers it symbolizes both respect and unrequited love.

But if this all seems too much, you could just go with Daisy.

Pronounced DAF-uh-dil.
