Latin Name:  Amaranthus palmeri
Common Name:  Careless weed
Family:  Amaranthaceae
Author:  Wats.

Known Hazards:  No members of this genus are known to be poisonous, but when grown on nitrogen-rich soils they are known to concentrate nitrates in the leaves. This is especially noticeable on land where chemical fertilizers are used. Nitrates are implicated in stomach cancers, blue babies and some other health problems. It is inadvisable, therefore, to eat this plant if it is grown inorganically.

Mature Height:  0.9   Mature Width:

Habitat:  Waste places and fields at low elevations, also in interior valleys and deserts in California[71].

Cultivation Notes: We have very little information on this species and do not know how well it will grow in Britain, though it should succeed as a spring-sown annual. The following notes are based on the general needs of the genus. Prefers a well-drained fertile soil in a sunny position[200]. Requires a hot sheltered position if it is to do well[K]. Plants should not be given inorganic fertilizers, see notes above on toxicity. Most if not all members of this genus photosynthesize by a more efficient method than most plants. Called the 'C4 carbon-fixation pathway', this process is particularly efficient at high temperatures, in bright sunlight and under dry conditions[196].
