Amaranthus, collectively known as amaranth, is a cosmopolitan genus of annual or short-lived perennial plants. Catkin-like cymes of densely packed flowers are borne in summer or autumn. Approximately 60 species are recognized, with inflorescences and foliage ranging from purple and red to green or gold. Members of this genus share many characteristics and uses with members of the closely related genus Celosia.
Although several species are often considered weeds, people around the world value amaranths as leaf vegetables, cereals, and ornamentals.
It is also known as "love lies bleeding"—it was used in the Middle Ages to stem bleeding.
The ultimate root of "amaranth" is the Greek ἀμάραντος (amarantos), "unfading," with the Greek word for "flower," ἄνθος (anthos), factoring into the word's development as "amaranth." The more accurate "amarant" is an archaic variant.
