Overview

• Teens and young adults amplify the gesture on TikTok and Instagram as part of Argentina’s Spring and Student Day celebrations, filling plazas and schools with yellow bouquets.
• Florists in Mexicali say the day now rivals Valentine’s and Mother’s Day, noting early stocking, extended hours to midnight in past years, higher prices and occasional shortages of yellow blooms.
• Flower markets in Lima, including Santa Rosa and Piedra Liza, report sales of sunflowers, roses and yellow daisies increasing by up to three times compared with typical weeks.
• The custom traces to a 2004 scene from the Argentine telenovela Floricienta, where the protagonist receives yellow flowers, a pop‑culture moment now recreated annually with the song “Flores Amarillas.”
• The observance aligns with the equinox—March 21 in the Northern Hemisphere and September 21 in the Southern Hemisphere—and the date also coincides with the United Nations’ International Day of Peace.
