  • 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.

Grey Goosefoot (Seaport Goosefoot)

Chenopodium opulifolium

NOT TRANSLATED YET. Grey goosefoot is very rare plant in Finland. Sen varsi on vihreä (raidaton), lehdet melko pieniä, meheviä, vinoneliömäisiä, yleensä harvaan hampaisia ja jauhoisia.

Chenopodium striatiforme

Chenopodium striatiforme (C. strictum ssp. striatiforme)

Hyvin harvinaisena meillä tavattavaa rannikkosavikkaa voi varmimmin tavata rannikoilta satamien läheisyydestä. Sen varsi on punavihreäjuovainen, lehdet 2–3 kertaa leveytensä pituisia ja harvaan hampaisia tai ehytlaitaisia.
