Description

Purple-headed sneezeweed can be found in forests or natural areas and along stream banks and in wet areas. It can become weedy in disturbed areas such as old fields, pastures, and roadsides. It is also used in flower gardens as an ornamental herbaceous perennial. It can be distinguished from other sneezeweeds by its round, purplish center disk. 

Sneezeweed can be cultivated in average to rich soils, needing moist to wet conditions. It should be cut back in early summer to encourage branching and increase flowers. Deadheading will encourage more blooms.
