Hi, Josh --
Based on what you've said, I have two suggestions for your honey:
1) Mariella Burani by Mariella Burani: A delicious floral with some citrus and spice notes and a *really* fun bottle (huge artificial flower on the cap). Can be had at any of the reliable online perfume websites for $35-$50.
2) Ivoire de Balmain: More old-school (like Rive Gauche), it has soft florals including rose, green notes and aldehydes. $30-$45 on the same reliable perfume websites.
Happy hunting, and I do hope you find something your girlfriend will enjoy! Keep us posted?
