Cockspur Patchouli, a photo by dinesh_valke on Flickr.

Indeed, Villoresi’s Patchouli is musty and earthy as you would expect from Pathcouli, but the Patchouli does not play as dominant role as does spikenard: there is a whiff of herbaceous-peppery patchouli top notes, which is instantly replaced by the musty, earthy dirt-and-moist-hay scent of spikenard. It does mellow a bit and reveals some more sweeter-patchouli at the dry down, and becomes a hint more powdery and sweet. However, if I would name this single-note composition I would choose to call it Spikenard.
Spikenard has a very distinctive aroma, so if you love the musty scent of moist earth after rain, you would love this perfume.
I love spikenard, but it does not wear well with my body chemistry. Another note of appreciation I have for this perfume is that it smells very natural, which is a quality I love about a perfume. It is sincere and non-overwhelming.
