Verbesina alternifolia (L.) Britton ex Kearney is the correct and accepted scientific name for this species. It was listed as such by Thomas Henry Kearney in Bulletin of the Torrey Botanical Club (New York) in 1893 (page 485) (I read through this publication and I don’t see where Nathaniel Lord Britton’s name is mentioned. It only mentioned  Actinomeris squarrosa Nutt. as a previous name). This species was first named Coreopsis alternifolia by Carl von Linnaeus in the second volume of the first edition of Species Plantarum in 1753.

The genus, Verbesina 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 by Kew lists 350 accepted species in the Verbesina genus (as of 6-3-21 when I wrote this page). It is a member of the plant family Asteraceae with 1,666 genera. These figures could change as updates are made by POWO. The number of genera in the family goes up and down quite often.

The above distribution map for Verbesina alternifolia 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 the same.

I found a nice colony of Wingstem (Verbesina alternifolia) on a friend’s farm on September 12 in 2019. There aren’t any of this species growing on my farm, but I do have Verbesina virginica (White Crownbeard, Frostweed). Both have winged stems which are always a great indicator you have found a species of Verbesina. I found another colony in the woods of another friend’s farm in May of 2020 but they weren’t flowering so I am not 100% sure which species the plants were. I was unable to go back to that location in 2020 when they were flowering, so hopefully, I can do that in 2021.

Missouri Plants includes three species of Verbesina in the state of Missouri. The only one I haven’t seen is Vesbesina helianthoides (Yellow Crownbeard) which flowers from May-October. Verbesina alternifolia and Vesbesina virginica flowers August-October.

I apologize for not writing descriptions at the moment, but I have A LOT of wildflower pages to make and publish before I start getting too busy. I update this site and add new pages over the winter but I didn’t get finished. SO, I decided to just make the page with photos and links to other sites for better plant ID. I will be taking more photos over the summer and posting but I will also be working on these pages as I have time.

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 identified over 100 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 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 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 (and if they update their sources or even read what they say). 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. 🙂
