White Crownbeard, Frostweed
Synonyms of Verbesina virginica (11) (Updated on 6-7-21 from Plants of the World Online): Phaethusa laciniata Small, Phaethusa virginica Britton, Sigesbeckia laciniata Poir., Verbesina laciniata Walter, Verbesina laciniata Nutt., Verbesina polycephala DC., Verbesina sinuata Elliott, Verbesina villosa Nutt., Verbesina virginica var. insularis B.L.Rob. & Greenm., Verbesina virginica var. laciniata A.Gray, Verbesina virginica var. mollissima B.L.Rob. & Greenm.
Verbesina virginica L. is the correct and accepted scientific name for the White Crownbeard. The genus and species were named and described as such by Carl von Linnaeus in the second edition of Species Plantarum in 1753.
Plants of the World Online by Kew lists 350 accepted species in the Verbesina genus (as of 6-7-21 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 virginica is from the USDA Plants Database. Areas in green are where the species is native. The map on Plants of the World Online doesn’t show as many states and also includes the species as being introduced to Jawa. Some data used to calculate where the species is native may be very old and not currently be present. On the other hand, the species could be more widespread.
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.

I first observed the Verbesina virginica close to the fence in the front pasture on my farm on October 10 in 2018. I had just begun to identify wildflowers on the farm so it was a great find. The White Crownbeard is a really neat plant with its winged stems. I photographed this species in the same area again on September 20 in 2020 and it doesn’t grow anywhere else on the farm but this one location. One of its other common names, Frostweed, comes from the way ice forms from its stems. Well, I didn’t go have a look when the time came so maybe I can try in the fall of 2021.
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 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 (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. 🙂
