While it's not an exact science, fragrances can be separated into various categories, or olfactory groups, if you will. Florals comprise the most popular and largest group of all of the perfume blends. Often carefully mixed with elements of fruity, spicy, or powdery notes, florals are known for their natural smoothness and feminine, romantic qualities.
Florals can be delicately blended together to create a wonderfully balanced bouquet or they can be "soli flora," meaning one floral note is used — the ever popular scent of rose, for instance.
Perhaps one of the most quintessential of the florals is the classic Chanel N°5 (price varies by type), which contains notes of ylang ylang, neroli, and jasmine, among others.
