Scientific profile
Amaranthus retroflexus is an introduced, herbaceous plant that reaches approximately 0.46 m in height, bearing broad leaves and non-woody stems. Flowering occurs between July and September. Ellenberg-type indicator values indicate a strong affinity for full sun (light value 8), fresh to moderately moist soil (moisture value 5), and calcareous to basic conditions (reaction value 7). The species is a pronounced nitrogen indicator, associated with nutrient-rich sites (nutrient value 8), and can tolerate slight salinity (salinity value 1). It is typically found in habitats subject to low disturbance severity (0.84). Its seeds are minute, averaging around 0.4 mg. In Great Britain the plant is treated as an introduced and established neophyte.
