This one smells stunning....on women. It has prominent floral heart notes which smell a tad too feminine to my nose. Aubepine might be responsible for the bug spray accord which makes an appearance 10 mins into the fragrance's evolution.
There are two kinds of mimosa: Acacia Farnesia (cassie absolute) and Acacia decurrens. Both have a slightly green character, but cassie absolute is more intensely floral while Acacia decurrens has a cucumber like fresh accord. Going by what I smell in Aubepine Acacia, its probably the cassie absolute which is the type of mimosa/acacia listed. Cassie absolute is expensive, so that probably contributes to the cost.
