Phlox divaricata L. is the correct and accepted scientific name for the Wild Blue Phlox. The genus and species were both named and described as such by Carl Linnaeus in the first volume of the first edition of Species Plantarum in 1753.

Plants of the World Online lists 69 accepted species in the Phlox genus (as of 5-17-20 when I am updating this page). It is a member of the Polemoniaceae Family with a total of 27 genera. Those numbers could change periodically as updates are made.

The above distribution map for Phlox divaricata is from the USDA Plants Database. The map on Plants of the World Online is MUCH different and doesn’t show near the range. I am sure someday they will update and they will be the same. It is a work in progress.

There are several links at the bottom of the page for further reading and to assist you with a positive ID.

There are several areas where Phlox divaricata is growing in nice colonies along the highway west of town. Where I live, there is a colony of Hesperis matronalis (Dame’s Rocket) which is easily mistaken for Phlox from a distance. The main difference right off is Phlox has five petals and the Hesperis has four. Phlox is in the Polemoniaceae Family while Hesperis matronalis is in the Brassicaceae Family.

A friend of mine lives along a highway with several nice colonies and I wanted to stop and take photos many times but didn’t. He has a nice secluded section of woods that I observed many wildflower species in including Phlox divaricata. That is where I took these photos.

I have many wildflower pages to add so I decided to upload the photos I have taken and come back later to write descriptions. There are several very good links at the bottom of the page for further reading that give very good descriptions.

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 thebelmontrooster@yahoo.com. I would enjoy hearing from you especially if you notice something is a bit whacky

NOTE: Plants of the World Online is the most up-to-date database. It is very hard for some to keep with name changes these days so you may find a few discrepancies between the websites. Just be patient. Hopefully, someday they will be in harmony. 🙂
