Oregon gumweed is a robust and resilient native perennial that produces striking sunflower-like yellow blooms from mid-summer until fall. Adapted to arid environments, it readily grows in gravelly or nutrient-poor soils, making it an excellent choice for xeriscaping, restoration projects, and wild gardens. Its deep root system and high drought resistance make it an ideal, low-maintenance plant for dry landscapes. The sticky flower buds, from which it gets its "gumweed" name, are a distinctive feature and also serve as a food source and habitat for pollinators.
