| Related species: |
Of the almost 100 species contained in the genus, only the relatively seldom A. graecizans L. and A. lividus L. were originally at home in Europe. All others were and are only cultivated as decorative plants, and have emerged out of gardens or, together with seed or wool, were brought in from tropical countries. Some of them have taken root and are quite common; others can be found only sporadically and are mainly at home in the neighborhood of trading depots or spinning companies. The flowering time lies between June and October.

|
| Allergology: |
Because of relatively small pollen amounts, it is insignificant as an inhalation allergen; the Amaranthaceae is botanically closely related to Chenopodiaceae and because of this has similarities with this antigen. On sensibilization to white goosefoot, a positive testing can often be assumed.
