Overview

• Observed informally this Sunday, September 21, the custom centers on gifting yellow blooms as spring begins in the Southern Hemisphere, with a parallel cycle on March 21 in the north.
• The trend’s popular origin traces to the 2004 Argentine telenovela Floricienta and its song “Flores amarillas,” which social-media users reactivated and viralized starting in 2022.
• Merchants in Peru report sharp spikes in sales—claims of demand rising up to roughly 300%—as shoppers seek themed arrangements for partners, friends and family.
• Common choices include sunflowers, yellow roses, tulips, lilies, gerberas and chrysanthemums, selected for symbolic notes like joy, friendship, optimism, renewal and romantic affection.
• The date coincides with the UN’s International Day of Peace, and some coverage links the yellow-flower gesture to broader messages of hope and harmony, though it remains an informal tradition.
