About

Helenium autumnale is a North American species of flowering plants in the family Asteraceae. Common names include common sneezeweed and large-flowered sneezeweed.

How to grow it

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 0.91 metres (3 ft) tall and is orange streaked with gold.

Where it grows

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, nor in the four Atlantic Provinces of Canada. It grows in moist, open areas along streams and ponds as well as wet meadows.
