Etymology
The term 'Helianthus' derives from Greek roots: 'helios', meaning 'sun', and 'anthos', meaning 'flower'. The name reflects the plant's characteristic of turning its flower heads towards the sun, a phenomenon known as heliotropism. Sunflowers are native to the Americas and were first domesticated by Native Americans for food and ornamental purposes. Over time, sunflowers spread to Europe and became popular not just as a crop but also for their aesthetic appeal in gardens. The cultivation of helianthus for oil extraction began in the early 19th century, leading to widespread agricultural practices across the globe. Today, sunflowers are a symbol of warmth and positivity, as well as an important source of food and oil.
