Chenopodium album, called white goosefoot, lamb’s quarters or melde (in Italian ‘farinetto’ or ‘farinaccio’).
It’s considered a weed in corn and potatos field such as in ornamental and veggie garden, but in Asia or Africa it’s grown as food (like spinach) for men and animals (chickens and poultry).
Its pollen may cause to hay fever and allergies.
But it has a useful role for our plants: it attracts leaf miners and the beet leafhopper, which transmits curly top virus to beet crops.
Leaves and young shoots may be eaten like spinach, but its high levels of oxalic acid have to be considered in case of kidney stones, rheumatism, arthritis and gout.
It produces black little seeds rich in protein, vitamin A, calcium, phosphorus, and potassium.
