A genus or group of flowering plants related to sunflowers, characterized by their yellow flowers and sun-seeking behavior.
From Greek 'helios' (sun) and 'anthos' (flower), with the Latin suffix '-ium' commonly used for plant genus names. This botanical term emerged in plant taxonomy during the 18th-19th centuries.
The '-ium' ending tells you this is likely an older botanical classification—modern plant science has reorganized these plants, but the name still echoes how early botanists were amazed by flowers that track the sun!
