Sneezeweed  (Helenium autumnale)

Sneezeweed (Helenium autumnale)

Easily grown in average, medium 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 a more floriferous 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.

 

Helenium autumnale, commonly called sneezeweed, is an erect, clump-forming  occurs in moist soils along streams, ponds or ditches and in spring-fed meadows, prairie and wet open ground throughout most of the State (Steyermark). Typically grows 3-5' 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 rays (three-lobed at the tips) and prominent, dome-like, dull yellow center disks. Flowers appear over a lengthy late summer to autumn (sometimes to first frost) bloom as indicated by species name. Alternate, lance-shaped, dark green leaves (to 6" long).
