Description and Ethnobotany

Growth Form An annual herbaceous plant with erect growth habit, can grow up to 1 m tall.
Foliage Leaves glabrous, petiolate; blade ovate, rhomboid or ovate-elliptic shaped; measuring 3 - 9 cm in length and 3 - 6 cm in width; base obtuse, apex emarginate; margin entire to sinuate. Cultivars have varying patterns of yellow, red and green foliage.
Stems Stem slender, herbaceous, sparingly branched. 
Flowers This species is monoecious, having separate male and female flowers on the same plant. Small, greenish flowers are borne in a radial pattern along a spike inflorescence which is often branched. The flowers are wind-pollinated and can also self-pollinate.
Fruit Seeds subglobose-shaped, dark brown to black, about 1 mm in diameter.
Similar This species looks similar to other Amaranthus species, but its wrinkled fruits and pointed flower bracts (< 1 mm long) are distinctive.
Cultivation Avoid feeding plants with too much nitrogen, as it may cause the plant nitrate content to become too high. Excessive consumption of nitrate may cause adverse health effects.
Etymology The genus Amaranthus means unfading, which refers to the long-lasting flowers.
