説明

Amaranthus spp. is an annual, erect herb (up to 1 m tall) grown for its edible leaves Leaves grow up to 8 cm in length and are present in an alternate arrangement along the stem.  Small flowers are borne on slender spikes within inflorescences up to 12 cm long. Fruit are small, compressed, oval-shaped seeds (1 mm in diameter) and glossy black in color.

使用方法

A. spp. is grown as a green vegetable. Leaves and young stems are prepared similar to other cooked leafy crops: boiled, sautéed, fried, added to soups, stews, or stir-frys. Seed production is minimal compared to biomass and is rather small. However, if harvested, seeds can be cooked similar to other amaranth pseudocereals: roasted, boiled, sprouted, or fermented. Plants are also used for livestock fodder.
