Solanum americanum Mill. is the correct and accepted scientific name for the Black Nightshade. It was named and decried by Philip Miller in the 8th edition of Gardeners Dictionary in 1768.
The genus, Solanum L., was 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 lists 1,224 species in the Solanum genus (as of 5-23-21 when I last updated this page). The genus is a member of the nightshade family, Solanaceae, with 100 other genera. Those numbers could change as updates are made by POWO.
The above distribution map for Solanum americanum 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 doesn’t show near the range for the United States and Canada.
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 spotted a few Solanum americanum, the Black Nightshade, on the farm while taking wildflower photos for a post on September 14 in 2018. Strange I had never seen these plants before even though I have been in the spot they were growing many times over the summer. I thought they were Black Nightshade even though I had not seen one in person before. I double-checked with a few websites and they were indeed Solanum americanum. I went back to take more photos after a couple of days and the plants were completely gone… I suppose the only explanation would be that the cows ate them. I find that quite weird since they had apparently been there for quite some time for the plants to have been as big as they were. Why would the cows just decide to eat them then? These plants are highly toxic, even to livestock… Unfortunately, I have not seen any more Black Nightshade on the farm or anywhere else I go wildflower hunting since 2019…
There are several common names, including Deadly Nightshade. Personally, this plant reminds me of the Grim Reaper…
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.
Maybe I will find the Solanum americanum in 2021 so I can take more photos. I need photos of the stems and leaves…
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 email@example.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. 🙂
