Synonyms of Helenium flexuosum (14) (Updated on 10-20-21 from Plants of the World Online): Heleniastrum nudiflorum (Nutt.) Kuntze, Heleniastrum parviflorum Kuntze, Helenium atropurpureum Kunth & C.D.Bouché, Helenium brachypodum Alph.Wood, Helenium floridanum Fernald, Helenium godfreyi Fernald, Helenium micranthum Nutt., Helenium nudiflorum Nutt., Helenium nudiflorum f. homochroma M.D.Howe, Helenium nudiflorum var. purpureum A.Gray, Helenium quadridentatum Hook., Helenium seminariense Featherm., Leptopoda brachypoda Torr. & A.Gray, Leptopoda floridana Raf.
Helenium flexuosum Raf. is the correct and accepted scientific name for the Purple-Headed Sneezeweed. It was named and described as such by Constantine Samuel Rafinesque in New Flora and Botany of North America in 1836.
The genus, Helenium L., was named and described as such by Carl von Linnaeus in the second volume of the first edition of Species Plantarum in 1753.
Plants of the World Online lists 32 accepted species in the Helenium genus (as of 10-20-21 when this page was last updated). It is a member of the plant family Asteraceae with a total of 1,677 other genera. Those numbers are likely to change periodically as updates are made by POWO. The number of genera in this family fluctuates often.
The above distribution map for Helenium flexuosum is from Plants of the World Online. Areas in green are where the species is native and purple where it has been introduced. The map on the USDA Plants Database for the United States and Canada is somewhat different and shows a few more states.
The map on iNaturalist shows where members have made observations. Anyone can join and it is a great website to confirm and share your observations. The maps on iNaturalist are continally updated as members post new observtions.
THERE ARE SEVERAL LINKS AT THE BOTTOM OF THE PAGE FOR FURTHER READING AND TO HELP WITH A BETTER POSITIVE ID.
I found this small colony of Helenium flexuosum on the farm in 2013 but I haven’t found it since then. I am sure it is here somewhere I just haven’t located it since then. Hmmm…
I observed over 100 wildflower species on the farm and other areas in 2019-2021 and am trying to get all their pages added. I am kind of behind but it is a work in progress. I will add descriptions later, but for now please refer to the links at the bottom of the page for further reading and accurate plant ID.
I have enjoyed photographing and learning about the many wildflowers growing on the farm and other areas. My farm is in Windsor, Missouri in Pettis County (Henry County is across the street and Benton and Johnson aren’t far away). I have grown over 500 different plants and most have pages listed on the right side of the blog. I am not an expert, botanist, or horticulturalist. I just like growing, photographing and writing about my experience. I rely on several websites for ID and a horticulturalist I contact if I cannot figure them out. Wildflowers can be somewhat variable from location to location, so sometimes it gets a bit confusing. If you see I have made an error, please let me know so I can correct what I have written.
I hope you found this page useful and be sure to check the links below for more information. They were written by experts and provide much more information. Some sites may not be up-to-date but they are always a work in progress. If you can, I would appreciate it if you would click on the “Like” below and leave a comment. It helps us bloggers stay motivated. You can also send an email to me at firstname.lastname@example.org. I would enjoy hearing from you especially if you notice something is a bit whacky.

NOTE: The data (figures, maps, accepted names, etc.) may not match on these websites. It depends on when and how they make updates and when their sources make updates. Some websites have hundreds and even many thousands of species to keep up with. Accepted scientific names change periodically and it can be hard to keep with as well. Some of the links may use a name that is a synonym on other sites. In my opinion, Plants of the World Online by Kew is the most reliable and up-to-date plant database and they make updates on a regular basis. I make updates “at least” once a year and when I write new pages or add new photos but I do get behind. We are all a work in progress. 🙂
