I’ve found these sprouting up in my yard. We just bought the property and have so far noticed that the previous owners planted a lot of medicinal herbs haphazardly so I’m wondering if this might be useful in some way but I can’t ID it. It’s growing on the south side of our home in Liberty, MO. Full sun, slightly clay-ish soil, well draining.
(This website is a spectacular idea!! I’m at glad it exists!)
your plant is a Field pennycress, Thlaspi arvensis. it is a common weed, not native, in the mustard family, Brassicaceae. It is especially common around crop fields in the spring. It has had some medicinal uses, but it is rarely planted as an herb.
Here is a great site with more information on this plant: http://www.survivalplantsmemorycourse.com/2013/05/thlaspi-arvense/
I hope this helps! I’m glad that you like our site! Feel free to post more!
