Liatris pycnostachya Michx. is the accepted scientific name for the Prairie Blazing Star. It was named and described as such by André Michaux in Flora Boreali-Americana in 1803.

The genus, Liatris Gaertn. ex Schreb., was described by Johann Christian Daniel von Schreber in the eighth edition of Genera Plantarum in 1791. He gave credit to Joseph Gaertner for naming the genus. 

Plants of the World Online by Kew lists 39 species in the Liatris genus (as of 10-21-21 when this page was last updated). It is a member of the plant family Asteraceae with 1,677 genera. Those numbers could change as updates are made on POWO. The number of genera in the family fluctuates quite often.

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. Observations that become research-grade have been agreed on by other members.

I found this Liatris pycnostachya (Prairie Blazing Star) along a back road south of town on 7-22-21. I knew it was a Liatris and thought it could be Liatris spicata since they are also a native of Missouri. I posted photos on iNaturalist and a member pointed out it was Liatris pycnostachya. I checked the page for that species on Missouri Plants and a few other sites and realized he was correct. Sometimes I see Liatris growing along the highway but I haven’t stopped to take photos.

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. 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. 🙂
