Helenium bigelovii is a North American perennial plant in the sunflower family, commonly known as Bigelow's sneezeweed. [2] It grows in moist areas such as meadows, marshes, or streamsides. It is found at moderate and higher elevations (3000–10,000 ft) in the foothills and mountains of California and Oregon: Cascades, Coast Ranges, Klamath Mountains, Sierra Nevada, etc. [3] [4] [5] Cultivars of the species are used in gardening as ornamentals.
Helenium bigelovii is a perennial herb sometimes as much as 130 cm (51 in; 4.5 ft) tall. One plant can produce as many as 20 flower heads, either one per branch or in branching arrays. Each head has 14-20 yellow ray florets (bending backwards and with teeth at the tips) surrounding sometimes as many as 800 disc florets (yellow at first, turning brown as they get older). [2] [6] [7] [8]
The species is named for J.M. Bigelow, a plant collector on the United States and Mexican Boundary Survey in the 1850s.
