Asclepias viridis Walter is the correct and accepted scientific name for this species of Milkweed. It was named and described as such by Thomas Walter in Flora Caroliniana in 1788.
The genus, Asclepias L., was named and described as such by Carl von Linnaeus in the first volume of the first edition of Species Plantarum in 1753.
Plants of the World Online by Kew lists 206 species in the Asclepias genus (as of 4-11-21 when Last updated this page). It is a member of the plant family Apocynaceae with 357 genera. Those numbers could change as updates are made.

I don’t have any Asclepias viridis, Green Milkweed, growing on my farm. I found them and many other wildflowers I was unfamiliar with while working in a friend’s pasture in 2019. I always take a lot of photos because you never know what they will look like when you upload them. There were quite a few colonies of Milkweeds of several species on his farm, but since the cows were grazing they had bit the tops off of most of them. I found one very nice colony of Asclepias viridis they hadn’t touched.
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 figures 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. 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 and add new photos but I do get behind. We are all a work in progress. 🙂
