Amaranthus deflexus, commonly known as Low Amaranth or Argentina Amaranth, is an annual herb that is native to South America, specifically in open, disturbed areas such as roadsides and waste places. It typically grows to a modest height of up to 1 meter. This species is characterized by its erect, green to reddish stems and its broad, alternate leaves which can have a reddish tinge. The flowers are small, greenish, and arranged in dense clusters along the stem, blooming in summer and early fall. While not particularly showy, the plant is known for its hardiness and ability to thrive in poor soils.

Low Amaranth is valued for its resilience and is often used in urban settings where other plants may struggle. It is also used as a food crop in some cultures, with the leaves and seeds being edible. In cultivation, Amaranthus deflexus prefers full sun to part shade and can tolerate a wide range of soil types, though it thrives in well-drained soils. It is drought-tolerant once established and requires minimal maintenance. However, gardeners should be cautious as it can become weedy and potentially invasive outside its native range, particularly in temperate regions.CC BY-SA 4.0
