Summary
Slim amaranth (Amaranthus hybridus) is one of the most widespread wild amaranths, offering both edible greens and seeds. Its leaves are mild and versatile, while its nutrient-rich seeds can serve as a substitute for a staple grain. Although considered a weed in many regions, its resilience and abundance make it a vital survival and wild food resource. It thrives in moist, sunny environments but tolerates a wide range of conditions, ensuring its presence in both cultivated and disturbed habitats. A dependable food plant, slim amaranth demonstrates why amaranths were staple crops of ancient civilizations. The nutritious mildly flavoured leaves and young seedlings can be eaten raw or cooked and used as a spinach substitute. Seeds are used as a cereal substitute and used in porridges and bread.
Physical Characteristics

Amaranthus hybridus is a ANNUAL growing to 2 m (6ft 7in).
See above for USDA hardiness. It is hardy to UK zone 6 and is frost tender. It is in flower from July to September. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Wind. The plant is self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers moist soil.

Edible Uses:
Slim amaranth is an edible wild green and seed crop, highly valued across many cultures. The leaves are edible when young and tender, used raw in salads or cooked as a spinach substitute. They have a mild, slightly earthy flavor with no strong bitterness, though texture can be a little fibrous if harvested late. Brief boiling softens the leaves and enhances palatability [2-3]. The seeds are also edible and are produced in abundance. They are small, shiny, and usually black, though some reddish or brownish seeds may occur. Seeds can be eaten raw, but are better toasted or boiled, yielding a nutty, grain-like flavor. They are highly nutritious, containing complete protein (with lysine, unlike many cereals). Slim amaranth’s seeds can be ground into flour, cooked into porridge, or incorporated into breads and seed cakes[2-3]. Because it resembles Amaranthus powellii closely, the two are often confused — but both are edible and processed in the same manner [2-3]. Leaves and young seedlings - cooked as a spinach, added to soups etc or eaten raw[46, 61, 62, 159, 183]. The nutritious leaves have a mild flavour[K]. Seed - raw or cooked[22, 46, 61, 85]. Used as a cereal substitute, the seed is usually ground into a flour for use in porridges, bread etc. It is rather small, about 1mm in diameter[266], but is easy to harvest and very nutritious[K]. The seed can be cooked whole, and becomes very gelatinous like this, but it is rather difficult to crush all of the small seeds in the mouth and thus some of the seed will pass right through the digestive system without being assimilated[K].

Astringent
A tea made from the leaves is astringent[105, 222]. It is used in the treatment of intestinal bleeding, diarrhoea, excessive menstruation etc[222, 257].

Cultivation details
Prefers a well-drained fertile soil in a sunny position[200]. Requires a hot sheltered position if it is to do well[K]. Plants should not be given inorganic fertilizers, see notes above on toxicity. Cultivated as a food crop in India[46, 105], there are many named forms[183]. This species has the potential, through crossbreeding, of imparting early maturity to the white seeded grain amaranths[183]. Most if not all members of this genus photosynthesize by a more efficient method than most plants. Called the 'C4 carbon-fixation pathway', this process is particularly efficient at high temperatures, in bright sunlight and under dry conditions[196]. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is clumping, giving the plant a clumping habit. The predictable growth behaviour makes it easier to maintain without having to apply containment methods[2-1].

Plant Propagation
Seed - sow late spring in situ. An earlier sowing can be made in a greenhouse and the plants put out after the last expected frosts. Germination is usually rapid and good if the soil is warm[133]. A drop in temperature overnight aids germination[133]. Cuttings of growing plants root easily[206].

Weed Potential
Right plant wrong place. We are currently updating this section.
Please note that a plant may be invasive in one area but may not in your area so it's worth checking.
Easily controlled and not particularly competitive it is still considered weedy or invasive in Kentucky, Northeast US and other areas in the United States.
