Oregon Gumweed

Oregon Gumweed is a tough and resilient native perennial that produces striking sunflower-yellow blooms from mid-summer well into the fall. Adapted to arid environments, it grows easily in gravelly or nutrient-poor soil, making it an excellent choice for xeriscaping, restoration projects, and wildflower gardens. Its deep root system and natural resistance to drought make it an ideal low-maintenance addition to dryland landscapes. The plant’s sticky flower buds, which give gumweed its name, are a characteristic feature that also serve as a food and habitat source for pollinators.

Where Can You Grow Oregon Gumweed?
Best suited for Zones 5–9, Oregon Gumweed thrives in full sun and well-drained soil. It excels in rock gardens, dry meadows, roadside plantings, and areas with limited water.

History and Historical Uses
