Convolvulus arvensis L. is the correct and accepted scientific name for the Field Bindweed. The genus and species were 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 202 accepted species in the Convolvulus genus (as of 5-6-21 when I last updated this page). It is a member of the plant family Convolvulaceae family with 59 genera. Those numbers could change as updates are made (and likely will).
Convolvulus arvensis is very widespread as you can see by the above map from Plants of the World Online. Areas in green are where the species is native and purple is where it has been introduced. The map on the USDA Plants Database for North America is similar. 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.

One of the many plants I haven’t encountered before on my farm is the Convolvulus arvensis commonly known as the Field Bindweed. There were several flowering in the front area of a friend’s pasture with white flowers with five pale pink stripes. I saw one on the west side with all white flowers and information on Midwest Weeds and Wildflowers says they are commonly all-white or mostly pink. There are five pink bracts on the underside of the flowers which may be why the flowers appeared to have pink stripes. The bracts on the underside of the flower distinguish it from the Hedge Bindweed (Calystegia sepium). Their roots can grow from 8 to 30 feet deep with stems up to 9 feet long. Their roots can send up many shoots and a group of these can spread up to 20′ per year. They produce LOTS of seeds that are viable for up to 30 years!
The leaves kind of reminded me of small Morning Glories.
From the underside, you can see the five pink bracts.
In another area, there were plants with white flowers.
Don’t forget to check out the links below to websites that give better and more technical botanical language.
I have enjoyed photographing and learning about the many wildflowers growing on the farm and other areas. 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. 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.

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. 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. 🙂
