Helenium autumnale is a North American species of flowering plants in the sunflower family. Common names include common sneezeweed and large-flowered sneezeweed.[2][3][4]

Natural habitat and distribution[edit]

This plant is widespread across much of the United States and Canada, from Northwest Territories as far south as far northern California, Arizona, Louisiana, and Florida. It has not been found in southern or central California, New Hampshire, or the 4 Atlantic Provinces of Canada.[5][6][7][8]


Common sneezeweed is a perennial herb up to 130 cm (51 13 in; 4 13 ft) tall. In late summer and fall, one plant can produce as many as 100 yellow flower heads in a branching array. Each head has 11-21 ray florets surrounding sometimes as many as 800 disc florets.[9]


Common sneezeweed is cultivated as a garden perennial. There are multiple named varieties varying in color and height. 'Pumilum Magnificum' is a yellow variety about two feet tall. 'Bruno', a reddish brown cultivar, 'Kupfersprudel', which is yellow/orange, and 'Butterpat', which is golden, all grow 3 to 3.5 feet (91 to 107 centimetres) tall. 'Chippersfield Orange' is up to 4 feet tall and is orange streaked with gold.[10]
