Plant ID in MO

Trying to identify and get rid of this thorny weed growing all over my yard. Can anyone help?

Black Locust - Robinia Pseudoacacia... one of my favorite permaculture plants. Fixes nitrogen, edible flowers, excellent bee fodder, rot-resistant wood, has a small canopy when full grown, ect...

You or your neighbors must have at least one large tree producing the pods.

And another reason to love BL: Mason Bees! https://permies.com/t/15913/bason-bees/One-more-reason-love-Black

original post indicated "thorny", I would say it is honey locust...keep it mowed, unless you want to dig out lots & lots of root.

wild;)

I think the leaflets are too rounded to be honey locust. Honey locust leaflets are more pointed.

Honey Locust:

I know this topic is almost a year old, but I thought I would add my opinion for future permies browsing old topics (such as myself). It looks a lot like what my parents have on top of their root cellar. In the same family as the black and honey locust, but a different type. Theirs is technically classified as a shrub. If you want it gone, keep it mowed down. The ones on top of my folks' root cellar is where the lawn mower can't reach. I don't know how it was introduced, but It's been there for 20 years now. The oldest and largest is about 10ft tall with a trunk diameter of approx 4 1/2 inches. Theirs spread by roots, and once established, the root system is damn near impossible to kill. Its branches I would call "fuzzy" but there are thorns on the older and more developed parts. Flowers are pink and look similar to pea blossoms.

This is what my parents have:

I don't know if that's what plant that is, but it's a possibility. If you want it gone, I recommend keeping it cut down as if your life depended on it. It is prolific. Or you could turn it into a resource. The bees LOVE the flowers, and the wood can but put to use in some way.

Old topic I know~
I've had these in my yard; short of it, after a good rain I'd give a wiggle jiggle pull and near all of root would come out. Now I really don't have any.
As said mowing didn't really get rid of them. Tips me hat~
