Edible wild beans?

Hi, i have a lemon tree and in That tree is growing a bean plant , i cooked and it taste good and seems edible.

Any idea which plant is this?

More pics

yeah, those are edible. they look to be long beans, a family of cowpeas, Vigna unguiculata. the whole pods are edible too, especially when they’re young and tender.

I agree with Greg, cowpeas might also be known as field peas, black-eyed peas, pink-eye peas, crowder peas or even purple hull peas if the hulls were purple.

It bears saying: if you are unsure of what you have growing, confirm its identity before consuming it. Even seemingly innocuous things such as beans have poisonous lookalikes.

looks like black-eyed peas. immature, they're absolutely fabulous eaten like a green pea, and dry also great. they're a staple a bit north of where I live in Brazil.

Hi , here are some pictures of The dried Bean compared with vigna unguiculata.

Yes , It seems it's a wild versión of vigna unguiculata.The plant is  producing pods all The time since I came here (more than 3 months) . I also thought this can maybe be a non domesticated (peremnial) version of vigna unguiculata ( frejol Castilla) but a peremnial one that produces food all all The time but a friend told me it's an anual plant .

I love this plant, always producing edible pods that taste good ( as mushrooms) , also beans can be stored and leaves are edible . Plant doesnt occupy space because it grows interwined and supported but another plant and it's nitrógen fixer.

I have some questions. If this plant is not peremnial which  is The diferente between this plant and vigna unguiculata?

Do You know any peremnial similar than this that can be planted in The Amazon jungles and produce edible beans all The time?


I have another questions. This plant is being attacked by a particular bug that likes a Lot it's leaves. It only eat The leaves of this plant. Any idea which bug is this and how to get rid of this Bugs?

Yeah i'm not sure about the annual vs perennial. in this climate sometimes annuals can live for multiple years. I've never had one of these die before I've cut or pulled it out myself, so don't know how long they live.
The insect is what we call a vaquinha here, or a vaquita there, https://en.wikipedia.org/wiki/Diabrotica_speciosa . they do only eat bean leaves. i make a ferment out of onion and garlic skins and spray the leaves, either that or a soap or soap/garlic/oil spray, you need to reapply constantly, but it can help delay the inevitable.
I grow long beans that right now are full of vaquinhas, what we do is cut off the bad leaves before they get moldy, and let the new leaves grow in.

Hi Teresa, The one You have produces beans all The time or just specific months?

not all the time, but a few times a year (2 or 3). keep in mind the weather is changing here (so I can't say "may and november", it seems to always be different) and while it never gets cold enough to kill it, for some of the year it's too cold for beans to set flowers (usually around 13C, i think?). I think I'm a few zones colder than you, I'm closer to Patagonia than I am to the Amazon.

also cowpea/black-eyed pea (Vigna unguiculata) has sooooo many cultivars, in different sizes and colors (check out the pics here https://www.embrapa.br/en/cultivar/feijao-caupi-vigna ). the long-straight seed pods are the giveaway though.
