🌱 Fat-hen

Chenopodium album · Amaranthaceae (formerly Chenopodiaceae)

🧠 To remember it“White flour on the leaf means fat-hen shows its true colors” — its natural powder is its ID card.
Fat-hen — Chenopodium album

🔍 Identify it without mistakes

Erect annual plant, extremely common in gardens and cultivated land, recognizable by the whitish mealy powder covering the underside of young leaves and stems — hence the names 'lambsquarters' or 'goosefoot'. Alternate, diamond-shaped leaves with coarsely toothed edges. Small, petal-less greenish flowers in dense clusters.

  1. waxy white flour-like coating on young shoots and leaf undersides
  2. alternate, irregular diamond-shaped leaves
  3. stem often streaked with red-purple at the base
  4. tiny green flowers in dense spikes
  5. subtle, pleasant scent
Size30-150 cm
Floweringjuillet-octobre
Habitatcultivated gardens, rubble, wasteland, field edges, rich soils

⚠️ Not to be confused with

Fig-leaved goosefoot / other goosefoots (Chenopodium spp.)none (all species in the Chenopodium genus are edible)

To tell them apart: the entire genus is edible; just watch out for the neighboring redroot pigweed, which is also edible but lacks the characteristic white mealy powder
