Common sneezeweed (Helenium autumnale) is an upright perennial that produces an abundant bloom from July to September, with numerous bright yellow daisy-like flower heads. Its fan-shaped, drooping petals add a vivid splash of colour to naturalized gardens. Highly adaptable, this plant tolerates a variety of soil types, including heavy clay soils, and withstands periodic flooding. Reaching up to 80 cm in height, common sneezeweed is appreciated for its ease of care and its contribution to local ecosystems in Quebec.

Ecological Roles
Common sneezeweed plays an essential ecological role by attracting numerous pollinators, including bees, bumblebees, and butterflies during its flowering season. Its nectar and pollen provide vital resources for these insects, supporting local biodiversity. Its ability to thrive in moist, clay-heavy soils makes it an excellent choice for flood-prone areas or gardens with heavy soils, where it also contributes to soil stabilization and erosion prevention. Ideal for ecological gardens and riparian landscapes in Quebec, common sneezeweed supports native wildlife while adding a vibrant touch of colour.

Common sneezeweed seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
