Many parts of the plants, including the leaves and seeds, are edible, and are frequently used as a source of food in India and South America – where it is the most important Andean species of Amaranthus, known as kiwicha.
It grows up to 75 cm in height, best in full sun. It can handle a variety of conditions, both humid and arid. It is easily grown from seed.
In most of its range, it is planted as a summer annual. In temperate regions, plants can be started indoors in early spring and transplanted outdoors after the last frost.
Annual. Easily grown in moist, average, well-drained soils in full sun to part shade. Best flowering in full sun, but appreciates some afternoon shade in hot summer climates. Start seed indoors 6-8 weeks before last frost date or purchase starter plants. When grown from seed, flowers usually don’t appear until approximately 3 months after sowing. Set out plants after last frost date. Space smaller varieties 8-12” apart and larger varieties to 18” apart. Seed may be harvested from garden plants for planting the following year.
