Overview

• Southern Hemisphere countries mark the custom on September 21, while Northern Hemisphere observance typically falls on March 21.
• The date is informal and varies by region, as it is not an official holiday or legally recognized observance.
• Florists and retailers report heightened demand and advertise promotions around the date, with Peruvian outlets noting attractive prices for shoppers.
• Common choices include sunflowers, yellow roses and chrysanthemums, reflecting themes of joy, friendship, optimism and new beginnings.
• The practice, widely adopted by Gen Z, draws on the Floricienta lyric about wishing to receive yellow flowers, which helped fuel its viral spread on TikTok.
