Helenium flexuosum

Purple-Head Sneezeweed

The very dark-colored disk distinguishes Purple-Head Sneezeweed from other species of sneezeweed which have yellow-green disks. On all sneezeweeds, the yellow ray petals have three lobes which distinguish sneezeweeds from Black-eyed Susan and other yellow coneflowers.




Occurs along pond margins and streambanks, in ditches, wet meadows, wet pastures and on moist areas of glades.

Additional Information:
H. flexuosum and other species in the genus contain a lactone known as Helenalin. This compound is poisonous to various animals but has anti-cancer properties. This species is often found standing alone in pastures as cows will not eat it. The plant is quite striking when in full flower.
