The etymology of the word Helianthus annuus can be broken down as follows:
1. Helianthus: Helianthus is a combination of two Greek words: helios, meaning sun, and anthos, meaning flower. Therefore, Helianthus translates to sunflower. This name was given to the plant because its yellow petals typically resemble the appearance of the sun.
2. Annuus: Annuus is derived from the Latin word annuus, which means annual or yearly. It refers to the fact that the sunflower plant completes its life cycle within a single year, typically germinating, growing, flowering, and setting seeds before dying off.
