Love Rosabotanica. I wear it a lot, but it's so hard to describe! I have & love B. as well -- and I also own & like Florabotanica & Balenciaga Paris. They all have a unique herbal-woody crispness going on. The particular undertones that these Balenciaga fragrances share is unique and very hard to describe. They have an earthy quality.
An EDP, launched in 2013, here are Rosabotanica's notes, per parfumo.net:
Top Notes - Blue hyacinth, Fig leaf, Petitgrain
Heart Notes - Rose, Grapefruit, Cardamom, Pink pepper
Base Notes - White amber, Cedar, Vetiver, Patchouli, Woody notes
To me, it smells like crisp, cool fresh air -- plus vines & leaves & trees. Very back-to-nature. Clean & outdoorsy & earthy. I picture mountains & forests in Sept-Oct-Nov. I would wear this while poking around in shops in Gatlinburg TN in the Great Smoky Mts -- it would really match the air & scenery & vibe, I think.
To me, it's a wild & free bohemian scent. Fresh, cool, & sparkling, but in a green & brown way. Honestly, it takes me back to my college days in Michigan. There are floral notes, but mostly I smell the crisp, cool, fresh, herbal, natural outdoors.
Rosabotanica can be a love-or-hate fragrance, I think -- anything unique tends to be -- and I loved it at first sniff. The bottle is a gorgeous work of art! When I'm really in the mood for something *different*, I turn to my Balenciagas -- they're like nothing else out there.
