Helenium autumnale (Sneezeweed)

This sneezeweed is an erect, clump-forming, native perennial which occurs in moist soils along streams, ponds or ditches. Typically grows three to five feet tall on rigid, distinctively winged stems which branch near the top. Features clusters of daisy-like flowers (2" diameter) with distinctive wedge-shaped, bright yellow petals and muted yellow centers.

Additional Information:
Powdered disk flowers and leaves of this species have in the past been dried and used as snuff, thus giving rise to the common name of sneezeweed.

Home Owner Growing and Maintenance Tips:
Easily grown in average, medium wet to wet soils in full sun. Prefers rich, moist soils. Intolerant of dry soils. Avoid overfertilization which may cause plants to grow too tall. Although not required, plants may be cut back in early June (at least six weeks before normal flowering) to reduce plant height and to encourage branching, thus leading to more bloom, healthier foliage and less need for support. Remove spent flowers to encourage additional bloom. Cut back plants by 1/2 after flowering. Divide clumps as needed (every 3-4 years) to maintain vigor. No serious insect or diseases.
