Chenopodium album

  • Name also: Fat-hen, Lambsquarters, Lateflowering Goosefoot
  • Family: Amaranth Family – Amaranthaceae
    (formerly Goosefoot Family – Chenopodiaceae)
  • Growing form: Annual herb.
  • Height: Commonly 10–100 cm (4–40 in.). Stem erect, hard, branched, usually red-striped.
  • Flower: Regular (actinomorphic), approx. 2 mm (0.08 in.) across. Perianth consists of 5 green, mealy (covered with glandular hairs) segments. Flowers almost stalkless, very small, borne in dense clusters. Stamens 5. Carpels fused at the based, gynoecium 2-styled.
  • Leaves: Alternate, grey-green, diamond-shaped or triangular, and covered with glandular hairs (‘mealy’). Blade-margins sparsely toothed, teeth blunt. Upper leaves with entire margins.
  • Fruit: Thin, membranous achene.
  • Habitat: Cultivated land, yards, roadsides, waste places.
  • Flowering time: June–September.

The species within subfamily Chenopodioideae are difficult to distinguish between. They often include several varieties whose identification usually requires the use of a microscope. One of the important distinguishing characters is the texture of the seed-coat. Genus Chenopodium is easily confused with oraches (Atriplex spp.). However, the latter have unisexual flowers and characteristic fruit-enclosing bracts. The scientific name of genus Chenopodium comes from Greek words ‘chen’ and ‘podion’ meaning goose and small foot. Maybe that is why the English name of many Chenopodium species is goosefoot.

Fat hen is a harmful annual weed. Its stem is often green-striped and leaf axils red. The glandular hairs on the stem and inflorescence make the plant mealy. Possible use of fat hen seeds and leaves both as food and fodder is frequently mentioned in the literature. As a weed it is most successful on nitrogen-rich soil as its drought resistance is enhanced by increased nitrogen availability.

Green Goosefoot (Swedish Goosefoot)

Chenopodium suecicum

Fat hen is often confused with green goosefoot which, however, usually does not have red leaf axils, and its leaf-blades are usually sharply toothed and have rather large teeth at the base.
NOT TRANSLATED YET. Yrttimielessä sekaannuksesta ei ole haittaa; molemmat lajit ovat hyviä lisukkeita ruokalautasillamme. Pohjanjauhosavikka on yläosasta vähempihaarainen sekä varrelta ja lehtihangoilta vähemmän punainen. Pohjanjauhosavikan lehdet ovat keskimäärin terävämpikärkisiä ja -hampaisia ja kehälehdet hedelmävaiheessa selvästi köliselkäisempiä.

Quinoa

Chenopodium quinoa

NOT TRANSLATED YET. Kirjallisuudessa on useita viitteitä siitä, että jauhosavikan siemeniä ja ehkä myös lehtiä on käytetty sekä ihmis- että eläinravintona. Samaan sukuun kuuluvan, eteläamerikkalaista alkuperää olevan, Suomessakin nykyisin viljeltävän kvinoan siemeniä on meilläkin saatavissa hyvin varustetuista kaupoista. Inkojen jo tuhansia vuosia sitten käyttämät kvinoan siemenet ovat gluteenittomia ja sopivat hyvin keliakiaa poteville.
