When Argentines Give Yellow Flowers in September, and Why

In Argentina, yellow flowers arrive with spring. On Sept. 21, people give them to loved ones in a tradition that took hold through social media and continues to attract new followers.

The custom is closely tied to Floricienta, the youth television series created by Cris Morena. Its song “Flores amarillas” tells of the young protagonist’s childhood dream of receiving yellow flowers, helping turn that detail from the show into a mass online trend.

The origin of the commemorative day is not known precisely. Yellow traditionally represents peace, harmony and prosperity, but in this case the gesture points directly to Floricienta, which premiered in 2004 and remains popular.

The series follows Florencia Santillán, an upbeat, somewhat clumsy orphan played by Florencia Bertotti. She works in music and becomes a nanny for the Fritzenwalden siblings after meeting their family at one of her events. The flowers became especially memorable in a first-season scene in which Franco, Federico Fritzenwalden’s brother, sends hundreds to Flor while trying to win her over.

The song later reinforced the tradition. In its video, set in the 1950s, Flor waits for Máximo to give her the yellow flowers she longs for as a gesture of love. The scene became a landmark of popular culture, and platforms such as TikTok gave it renewed visibility.
