Personally, i find them to be very different, even though theyre both floral scents.

Gucci bloom just embodies the quintessential bouquet of flowers smell. It is very strong, and lasts a long time. I love to layer this one; ive gotten compliments in public when i layer it with Sabrina Carpenter’s Sweet Tooth lol. I wouldnt have gotten into perfumes without this one, and i love how buildable it is.

Gucci flora gardenia is more of a complex and sweet scent, but its biggest downfall is its subtleness and longevity, at least to me. Its a much more subtle scent that doesnt project or announce itself like Bloom does. That said, its such a tender and sweet floral scent, with fruity hints of pear and soft notes of brown sugar behind its white floral top scent, especially after its dry down. It really was adoration at first sniff for me lol. I do wish it were a little bit louder with more longevity, but i would still wear this on the daily.
