Pigweed (Portulaca oleracea) is an annual, succulent herb. It is native to either South America or North Africa, and features a thick tap root with many fibrous secondary roots, forming a prostrate mat of up to 60 cm in diameter.

Several species of pigweed, particularly Amaranthus retroflexus, can be responsible for acute tubular necrosis and perirenal edema in pigs and cattle. The toxic principle is likely a group of phenolic compounds present in the leaves.

Also known as black pigweed, this species is considered a native of tropical areas, and in Australia is largely found in the Northern Territory, Queensland, and northern New South Wales.
