Overview

• Observed on September 21 in the Southern Hemisphere, the equinox-linked custom saw widespread participation across Argentina, Mexico and Peru.
• Florists reported surging demand and extended hours; in Mexicali some shops prepared months in advance, stayed open until midnight, and independent vendors tallied 100-plus customers with dozens of bouquets sold.
• Lima flower markets such as Santa Rosa and Piedra Liza reported sharp increases, with demand for sunflowers, yellow roses and gerberas reaching up to triple a normal week.
• The gesture traces to a 2004 Floricienta episode and its song Flores Amarillas, later revived by TikTok and Instagram into a recurring seasonal ritual.
• The practice also recurs on March 21 in the Northern Hemisphere, and this year’s feeds featured viral moments from a bus driver delivering a bouquet to playful edible “bouquets” in place of flowers.
