perennial legume ornamental grass 9A

Ideally :

1-3 feet tall

clumping

legume

ornamental grass or similar

I expect it to choke out or stop any other plant growth within its area.

Is there such a thing and if so is there a list of my options?

I have an area of my property that is sloped seen at approx 17 min into this video  https://www.youtube.com/watch?v=HqXfNVf2zyg&t=684s

I plan to plant a seabreeze bamboo ( Im working on propagating ) in this area and Id like to plant a perennial legume that will eventually become so thick that it chokes out any other weeds. This is a very large area, I could use this material as a chop and drop for my other plants over time.

Dosent have to be ornamental grass, Im open to anything but Id like it to be 1-3 foot tall ( preferably clumping )  

Does this exist?

This is important to me, I hope the experts will respond. Not trying to be a pesk

Thank you. looks like western united states, Im in N. Florida, will look into it further

Let me know what you think of perennial peanut+dutch white clover

legumes (Fabaceae) and grasses (Poaceae) are very different families of plants, but i think there are nitrogen-fixing bacteria that associate with some grasses if that’s what you’re after.

i feel like anything that’s really clumping in growth pattern won’t be able to outcompete lots of weeds until the clump is so big it’s a problem in its own right.

Chickens are 1-3ft tall, clump together at night, and are nitrogen producers that will eradicate many weeds, but alas they are neither legumes nor grasses.

I don't know, but the contradictory terms "legume" and "ornamental grass" confused me, and might confuse others, which might be why you are not getting replies. Are you looking for an ornamental legume? Or an ornamental grass and not a legume? Or... ???

I do not know what is going on with the link I posted in the first post of my property, when I click it I am brought to a valve adjustment procedure that I have saved in my liked videos on you tube, anyway here is a link to a thread I started with the video https://permies.com/t/146742/Video-property

About 17.00 minutes into it you will see a sloped area, I cannot mow a majority of it and I need to keep it from eroding

I want to plant a perennial there that will make the most sense.

Ideally Id like it to be a dense covering so that it will out compete any weeds

Ideally no taller than 3 ft, drought tolerant well draining sand

Id also like to plant something useful there, something that will serve a purpose, something that will build soil not only there but possibly as a chop and drop.

What might my options be? Thanks for asking for clarification

Perennial peanut is something I am looking into, I will google the clover still
