Summary
The leaves, stems and seeds of Palmer amaranth or carelessweed are edible and highly nutritious. The leaves are cooked as a spinach. The seed is also cooked and then used with cereal flours in porridge and breads. It is native to most of the southern half of North America. Common names, including carelessweed, dioecious amaranth, Palmer's amaranth, Palmer amaranth, and Palmer's pigweed.
Physical Characteristics
Amaranthus palmeri is a ANNUAL growing to 0.9 m (3ft).
See above for USDA hardiness. It is hardy to UK zone 8 and is frost tender. 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 and can tolerate drought.

Edible Uses
Edible Parts: Leaves Seed
Edible Uses:
Leaves - cooked as a spinach[46, 85, 95, 105, 161]. The leaves can also be dried for winter use[257]. Seed - cooked[46, 85, 95, 105, 161]. Very small but easy to harvest and very nutritious. It is usually ground into a powder and then used with cereal flours in making porridge, bread etc[257]. 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].

Cultivation details
We have very little information on this species and do not know how well it will grow in Britain, though it should succeed as a spring-sown annual. The following notes are based on the general needs of the genus. 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. 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].

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].
