Sunflowers have phototropism, and people call them sunflowers, flowers that follow the sun. In the ancient Inca Empire, sunflower was the symbol of the sun god. Therefore, the flower language of sunflower is the sun, silent love and admiration.
The yellow color of sunflower stands for nostalgia, love and so on, while the orange color stands for joy, friendship and harmony. It usually attracts much attention as the main flower in the bouquet and never appears as a matching flower.
Because December 5th is Father's Day in Thailand, and the floral meaning of sunflower usually means "father's love" and "respect", sunflower is the main ornamental flower and gift flower for Father's Day. ?
Extended information
There was a sad Greek legend about sunflowers. Clytie is a goddess of the sea. She was the lover of Helius, the sun god, but later Helius fell in love with Leucothoe, the princess of Persia.
Clytie, who was furious, told Orcham, king of Persia, about the relationship between Ryukyu and Helius. Erkamos ordered the unfaithful daughter to be buried alive. When Helius learned about this, he completely cut off contact with Clytie. Clytie, who was infatuated for several days, didn't eat or drink, and watched Helius drive a solar car up and down, languishing day by day, and finally turned into a sunflower (sunflower).
