Torilis arvensis (Common Hedge Parsley) is one of those species you love to hate. I remember as far back when I was a kid coming inside from playing and having those darn stick-tights stuck to my socks. My mother would have to remove them from my socks before washing the clothes until she decided to teach me a lesson. One day, she didn’t remove them and when I went to put on my socks, the stick-tights were still on them. From then on, I tried to avoid them. 

Even now, I despise wildflower hunting and walking through a patch of the Hedge Parsley. Even if I need photos of a plant behind them, I try to find a way around… 

Torilis arvensis is often confused with Torilis japonica even by the experts. They are very hard to tell apart and I believe for a while they have been synonyms of each other. The reason I am saying the plants on the farm are Torilis arvensis is because they were first discovered in Missouri (officially) in 1909 in Jasper County and are now found in every county. The first official specimen of Torilis japonica wasn’t collected in Missouri until 1988… Well, I was getting these darn seeds on my socks in the 1960’s so I suppose they had to be Torilis arvensis. 🙂 Who knows? One thing for sure is they are a pain in the neck…

WELL… I had uploaded photos of Torilis arvensis on iNaturalist, and a member asked if I was sure they weren’t Torilis japonica? I never gave much thought to it but as time went by I became curious. What if the Hedge Parsley here were actually Torilis japonica? That thought festered until I just had to know… SOOOO, on July 11 (in 2021) I took my magnifying glass to get a closer look…

One of my favorite wildflower sites, Missouri Plants, has a page for Torilis japonica and says Torilis arvensis is a synonym. It is a great website, but a little out-of-date as far as some accepted names are concerned (only a few). Plants of the World Online and most other databases list both species as accepted. Illinois Wildflowers states Torilis japonica “has about 8 linear bracts at the base of each compound umbel, and the bristles of its seeds have hooked tips.”

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 foliage of young Torilis arvensis and T. japonica can be mistaken for a few similar-looking species, but around here, they grow just about everywhere so I am pretty used to it. They have nice-looking foliage, but once they start to flower they get yanked up. Even so, there are plenty they escape being pulled up to go to seed…

SO, here I am on July 11 to check for hooked tips with a magnifying glass. The above photo are from old seeds, likely leftover from 2020. I couldn’t really tell.

The above cluster was suspicious…

Hmmm… HOLY CRAP! There are hooked tips!!!

Torilis japonica (Japanese Hedge Parsley) on 7-11-21, #810-19.

I checked the fruit on several colonies, and I was shocked to see their fruit all had hooked tips. Now, isn’t that weird?

Torilis japonica (Japanese Hedge Parsley) on 7-11-21, #810-20.

Well, one thing is for sure, you sure can’t tell by the flowers or leaves…

Torilis japonica (Japanese Hedge Parsley) on 7-12-21, #811-2.

I took A LOT of photos trying to get a good one of the hooked tips. They are really hard to close-ups of…

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. 🙂
