Hey coopmom - I haven't sniffed it so can't tell you anything about Fleur de Vanille, but I adore Fragonard and several of their scents are among my favorites; Belle de Soleil, Capucine, Belle de Nuit, Soleil, Miranda, Cette nuit là, Eclat, Fragonard, Eau Fantasque, Cerisier en Fleurs, Fleur d'Oranger, etc., (...and I could go on, lol!) Even if one of their fragrances doesn't really suit me, I generally find myself rating it at least 3 stars for overall beauty, high quality, surprisingly good longevity and excellent affordability. I also respond well to any line that offers most of their fragrances in bath products as well as edt, edp and/or parfum, as they do. Plus, I love their website. And their packaging.
They have a new range out that I'm anxious to try - Cèdre, Vétiver, Patchouli and Santal. They do a very nice job with solifores, so I'd imagine these would be quite good, as would the Fleur de Vanille, which is another one I've been eager to try. I sometimes use the body lotion or shower gels to get a good idea of the fragrance before I buy it, but their edts are so affordable I don't mind saying I've bought several of them almost blind (after only rubbing a moistened sample sachet on my wrist - just enough for almost a full wearing.) But I just don't think you can go wrong with Fragonard so the risk is pretty low if you decide to try it out. (They have several little boxed sets of minis with some of their classic perfumes and natural eaux - great bargains and plenty enough to get a good idea of whether or not you need a full bottle. Unfortunately, not all of their scents are offered in these minis, hence the almost blind-buying.)
Btw, according to Fragonard, Fleur de Vanille is comprised of notes of "sensuous vanilla flowered with ylang, heliotrope and rose on a sweet harmony of chocolate, cocoa and musk." Chocolate and cocoa, huh? Whatevs - sounds yummy.
