Arrowleaf Groundsel, scientifically known as Senecio triangularis, is a herbaceous flowering plant belonging to the Asteraceae family, native to North America. It is primarily found in western regions of the United States and Canada, growing in a variety of habitats including meadows, woodland edges, and open slopes.
The Arrowleaf Groundsel derives its name from the distinct arrowhead-shaped leaves that are green-gray in color and grow in a rosette formation, giving it an attractive appearance. The leaves are typically toothed along the margins and covered in fine hairs. This perennial plant can reach a height of up to 2 feet (60 centimeters) and produces multiple flowering stems with bright yellow, daisy-like flowers. The flowers are clustered at the end of each stem and have numerous elongated petals surrounding a yellow center.
Arrowleaf Groundsel is known for its adaptability and ability to thrive in a variety of soil types, including sandy, clay, and loamy soils. It is also tolerant of drought conditions, making it suitable for xeriscaping. However, it prefers well-drained soil and full sun to partial shade for optimal growth.
While Arrowleaf Groundsel is admired for its ornamental value in gardens and landscapes, it is important to note that the plant contains toxic compounds known as pyrrolizidine alkaloids. These chemicals can be harmful if ingested by animals or humans, causing liver damage or other adverse health effects. Therefore, caution should be exercised when handling or cultivating this plant, especially in areas accessible to livestock or pets.
The word "Arrowleaf" in "Arrowleaf Groundsel" refers to the shape of the leaves of this plant, which resemble the shape of an arrowhead. The term "Arrowleaf" is a combination of "arrow" and "leaf".
Meanwhile, "Groundsel" is derived from the Old English word "grundeswylige", meaning "ground swallower". This name was given to various plants belonging to the Senecio genus, which includes the Arrowleaf Groundsel. The name "Groundsel" likely originated from the plants' tendency to grow rapidly and spread across the ground.
