Southeastern sneezeweed (Helenium pinnatifidum)
Click on terms for botanical definitions.
Don’t let the name fool you — sneezeweed does not refer to the biological reaction one might have to smelling it. Rather, it is a reference to the plant’s historic use. Native Americans were known to dry and grind into a powder certain species of Helenium and use it as snuff.
Southeastern sneezeweed is an herbaceousperennial with delightful sunny blooms. Flowers are solitary and comprised of a broad and dense cluster of yellow diskflorets surrounded by many bright yellow ray florets, each with three lobes or notches. Flowers are 2–3 inches in diameter. Stems are erect, unbranched and may be pubescent or glabrous. They arise from a basalrosette of leaves that may have entire or slightly toothedmargins. Stem leaves are sessile, alternately arranged and become reduced as they ascend the stem. Seeds are borne in brown, hairy achenes.
Flowers typically bloom in spring, but may bloom year-round. They occur naturally in wet flatwoods and roadside ditches, and along marsh and swamp edges throughout Florida.
