Synonyms of Verbena hastata (10) (Updated on 5-31-21 from Plants of the World Online: Verbena hastata f. albiflora Moldenke, Verbena hastata f. caerulea Moldenke, Verbena hastata var. oblongifolia Nutt., Verbena hastata var. paniculata (Lam.) Farw., Verbena hastata var. pinnatifida (Lam.) Pursh, Verbena hastata var. rosea N.Coleman, Verbena hastata f. rosea (Coleman) R.H.Cheney, Verbena hastata var. scabra Moldenke, Verbena paniculata var. pinnatifida (Lam.) Schauer, Verbena pinnatifida Lam.

Verbena hastata L. is the correct and accepted scientific name for this species of Verbena. 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 150 species in the Verbena genus (as of 5-31-21 when I last updated this page). It is a member of the plant family Verbenaceae with 31 genera. Those numbers could change as updates are made by POWO.

The above distribution map for Verbena hastata is from the USDA Plants Database. The map on Plants of the World Online is similar but doesn’t show a couple of states. It also shows where the species has been introduced to Austria, Great Britain, and Jamaica.

POWO gets some of their maps for the United States and Canada from Flora of North America for families recognized on that site. When I wrote this page FNA had not yet included genera from the plant family Verbenaceae. The editor of POWO said they would start using maps from the USDA Plants Database for families not included on FNA later in 2021. 

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. Data from some sites come from old herbarium samples and the species may not even exist in some states now, or they could have a broader range. With iNaturalist, you get current observations as long as the species has been correctly identified and is research grade.

I first spotted and identified the Verbena hastata on my farm on September 8 in 2018. On July 25 in 2019, I spotted a few while working on a friend pasture north of town. Then, on August 2, also in 2019, I spotted a HUGE plant growing in the ditch along the street in front of the park. I had been watching this plant for a while but I never seemed to have my camera. Normally, the park caretaker keeps the ditch trimmed (or sprayed) so I knew I had to get photos. Finally, I walked down the road and took a few photos. The city park is next to my farm.

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.

The above photo and the next few are of the small colonyI found on a friend’s farm.

The Verbena hastata is a neat plant so hopefully I can find it again to take more photos. You ever know where wildflowers will turn up. I will get descriptions written as soon as I can.

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 (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. 🙂
