Amaranthus tricolor is an annual plant known for its brightly colored foliage rather than its flowers. This plant is grown as an edible crop in some parts of the world. The genus name comes from the Greek word amarantos meaning unfading in reference to the long-lasting flowers of some species. Specific epithet means three-colored.
