Is cowpea a weed

No, cowpea is not a weed.

Specifically, a plant can be considered a weed if it does not share resources and space with farmer-, gardener- or owner-desired plants, if it is where it should not be, or if its use is forgotten or unknown. The plant in question (Vigna unguiculata) does not meet any of the above-mentioned criteria unless the farmer, gardener or owner does not desire its presence on the property. Otherwise, cowpea is an attractive plant that knows how to share and that produces protein-high vegetarian food.
