Arrowleaf Groundsel, scientifically known as Senecio triangularis, is a perennial wildflower that is widely found in the western regions of North America. This beautiful plant is characterized by its arrow-like leaves with serrated edges and bright yellow flowers that bloom in late spring and early summer. Some of the synonyms for this plant include Arrowleaf Ragwort, Golden Groundsel, and Arrowleaf Senecio. These synonyms refer to the prominent arrow-like shape of the leaves, the golden hue of the flowers, and the scientific name of the plant family that it belongs to. Arrowleaf Groundsel is not only a beautiful addition to any garden but also has cultural and medicinal importance to several Native American tribes.
