Amaranthus graecizans (common name: spreading pigweed)

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[1]. A drop in temperature overnight aids germination[1].

Cuttings of growing plants root easily[2].

Cultivation: Prefers a well-drained fertile soil in a sunny position[3]. 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[4].

Range: N. America - in all areas except the extreme north. E. Asia.

Habitat: Disturbed or waste ground, Washington to California[5].

Edibility: Leaves - cooked as a spinach[5][6][7][8]. The nutritious leaves have a very mild flavour, they are often mixed with stronger tasting leaves[9][K].

Seed - raw or cooked[5][6][7][8]. Rich in starch[10], they can be used as a cereal substitute[9]. Very small but easy to harvest and very nutritious. 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].

Usage: Yellow and green dyes can be obtained from the whole plant[11].

Pollinators: Wind, self

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

In Leaf: Late Spring-Mid Fall

Flower Type: Monoecious

Known Hazards: No members of this genus are known to be poisonous, but when grown on nitrogen-rich soils they are known to concentrate nitrates in the leaves. This is especially noticeable on land where chemical fertilizers are used. Nitrates are implicated in stomach c
