Bloom! Floretta Pretty Cure! (ブルーム！ フロレッタプリキュア！,Burūmu! Furorettapurikyua!?) is the opening song of Floretta Pretty Cure!. The song is sung by Itou Shizuka, the voice actress of Hanayama Iris.
The opening begins with Iris, Alani, Mizu and Sakura staring up at the sunset with Iris turning around and making her trademark "peace sign". The title then follows the 4 as they transform into Romatin, Aloe, Myrtille and Primavera respectively. Phlox then starts dancing on the title causing it to turn into flowers and sparkles.
