Ballade Verte is rose chypre-ish, though it's not quite as angular and challenging as it develops as the 80s fragrances it reminds me of. As I first tried it I thought, This is what I can wear when I'm wishing I could experience Scherrer 2 the way I did when it came out. Because as much as I love the memory of Scherrer 2, smelling it now, there's no way.
I've seen the rose in Ballade Verte described as Moroccan, though it smells like an eglantine rose, the ones that grow wild. I might just be smelling rose + violet, because there's a little of that, too. But if you like wild rose, it's not that easy to find in fragrance, and this is a great facsimile of it, front and center.
Potent and great longevity, so go easy.
