About Amaranthus albus L.
Amaranthus albus L. is an annual herb that grows up to 50 centimetres (20 in) tall and produces many branches. When larger specimens of this species die and dry out, they become tumbleweeds. This plant produces small, greenish flowers that grow in dense clumps in the leaf axils, with both male and female flowers mixed together within the same clump. It is native to tropical Americas, but has been widely introduced and spread across other regions including Europe, Africa, and Australia. In Cambodia, this plant is called phti sâ in the Khmer language. Its leaves are used as feed for pigs, and are also sometimes cooked and eaten by humans.
