Flores Amarillas was performed by Florencia Bertotti as the heroine Flor in the Argentine youth telenovela Floricienta, which aired in 2004 and 2005. In the story, Flor dreams of receiving yellow flowers from the boy she loves, and the song became the show's anthem across Latin America. Years later, social media turned the lyric into a real tradition: partners surprise each other with yellow bouquets on September 21, Argentina's spring day, and on March 21 in the northern hemisphere. TikTok and Reels edits revived the chorus, keeping it the go-to sound for flower videos.
