Vigna vexillata, the Zombi pea or wild cowpea, is a variable, perennial climbing plant that is pantropical, found in regions such as Ethiopia, Nigeria, and Venezuela.

[4] Vigna vexillata thrives in a wide range of conditions, mostly in grasslands and in disturbed areas, as well as a weed.

[4] The plant is a very important food crop in several areas, such as Namibia, where it is commonly harvested from the wild for local use.

It is also grown as a green manure and ground cover crop, especially in poor soils.

The tubers have a soft, easily peeled skin and creamy flesh.
