Erechtites hieraciifolius (L.) Raf. ex DC. is the accepted scientific name for this species of Erechtites. It was described as such by Augustin Pyramus de Candolle in Prodromus Systematis Naturalis Regni Vegetabilis in 1838. He gave credit to Constantine Samuel Rafinesque for first naming and describing the species. It was first named and described as Senecio hieraciifolius by Carl Von Linnaeus in Species Plantarum in 1753.
The genus, Erechtites Raf., was named and described by Constantine Samuel Rafinesque in Flora Ludoviciana (Flora of the State of Louisiana) in 1817.
As of 11-24-22 when this page was last updated, Plants of the World Online lists 8 species in the Erechtites genus. It is a member of the plant family Asteraceae with 1,689 genera. Those numbers could change as updates are made on POWO.

The above distribution map for Erechtites hieraciifolius is from Plants of the World Online. Areas in green are where the species is native and purple is where it has been introduced. The map on the USDA Plants Database for the United States and Canada is similar and includes California and Oregon. There are a lot of maps online, and many are different. It depends on where they get their data.
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 continually updated as members post new observations.

Erechtites hieraciifolius (American Fireweed, ETC.) stem on 10-1-22, #913-9.
I first ran across this plant in the entry to the south hayfield on September 17 in 2022. It was a small plant, and pretty much in the shade. I went back on October 1 and found a larger plant so I took more and better photos. In optimal conditions, this species can grow to 9-10 feet tall. The plant I took the photos of was in full sun most of the day and was around 3-4 feet tall. I think I should start carrying a tape measure…

I am just adding photos for now, but I will come back later and write descriptions. I update the site, add new pages, add new photos to old pages, and write descriptions over the winter. Writing descriptions is difficult for me, but they say a photo is worth a thousand words. There are several links to very good websites below that have great photos and descriptions.

I live on a small farm in Windsor, Missouri where I enjoy gardening, collecting plants, and identifying wildflowers. The farm is in Pettis County but Henry County is across the street, and Benton and Johnson aren’t far away. I have grown over 500 different plants and identified over 250 species of wildflowers (most have pages listed on the right side of the page). 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 few horticulturalists I contact if I cannot figure them out. Wildflowers can be variable from location to location, so that can be 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 thebelmontrooster@yahoo.com. 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. 🙂
