Amaranthus tricolor, (edible amaranth)

Amaranthus tricolor, known as edible amaranth, is a species in the genus Amaranthus (family Amaranthaceae). The ornamental plant is known as bireum in Korea; tampala, tandaljo, or tandalja bhaji in India; callaloo in the Caribbean; and Joseph's coat after the Biblical figure Joseph, who is said to have worn a coat of many colors. Although it is native to South America, many varieties of amaranth can be found across the world in a myriad of different climates due to it being a C4 carbon fixation plant, which allows it to convert carbon dioxide into biomass at a more efficient rate than other plants. Cultivars have striking yellow, red, and green foliage.
