Yesterday and today I wore two fragrances that feature lavender in the top note. When I wore these two (Armand Basi Homme yesterday, and Rochas Man today), I had the distinct impression that I was smelling not lavender, but another, similar oil that I had smelled years ago: lavandin.
Those some years ago, I had a bottle of Parfums Régence Lavandin. I tried to track down this scent on the web, but all I could find is the much more talked-about Kölnisch Juchten (which is in my current collection). I had two other bottles of Parfum Régence scent: Clary Sage and Oakmoss. These are also missing from Google searches, and sadly, also missing from my collection now.
The thing about these Parfums Régence products is that they were very close to giving a genuine impression of the note named on the bottle, with just the minimum of other notes to make them wearable as stand-alone scents rather than as pure essential oils.
An the weird thing about the Lavandin was that it didn't smell too much like lavender; it was more herbal, more camphoraceous. It's not that lavender oils don't have those characteristics too, but that the lavandin note was different enough so ...
