Overview

• Argentines have embraced the Sept. 21 exchange of yellow flowers as a consolidated custom tied to the start of spring and Día del Estudiante.
• The modern tradition traces to Floricienta, where Florencia Bertotti’s character receives yellow flowers from Franco Fritzenwalden, played by Benjamín Rojas.
• TikTok and Instagram posts featuring the song Flores Amarillas have turned the gesture into a recurring annual trend across generations.
• Florists report notable demand spikes for sunflowers, yellow roses and yellow tulips in the days leading up to the date.
• The practice extends beyond romance to friends and family in Argentina and other Southern Hemisphere countries, with a parallel exchange in the Northern Hemisphere on March 21.
