Floral Power Fortissimo (フローラルパワーフォルテッモ Furōraru Pawā Forutesshimo?) is a duo attack that Cure Blossom and Cure Marine use in Heartcatch Pretty Cure!. It is one of the ways to purify a Desertrian, so it is considered a finishing move. The move can only be used if the Pretty Cures are together, although Cure Moonlight can use this attack by herself. This finisher can be used by any two of Pretty Cure as seen in episode 48.
Cure Blossom and Cure Marine summon their Flower Tacts. Pink and blue energy go into the gem of the tacts, with the heart gem glowing to signify it is full. Both Cures spin the center of the tact, and rainbow lights go into the gemstone tip of the tact. The tips surge with purity energy, and the girls spin before linking the tacts together. Declaring the attack name, they draw ƒƒ with their tacts. Energy surrounds their bodies and they charge for the enemy, covered in light colored their respective theme color. They come together and burst through the enemy, a heart shaped imprint on the target's chest. The girls land behind the enemy with the victim's Heart Flower above them and yell "Heart Catch!". An implosion occurs, and the target is suspended in the air, the girls' respective flowers having overlapped behind it. Both girls clap the center of the tacts to keep the center spinning and in a flash of light, the enemy is purified.
