Ecology

Alhagi maurorum is a noxious weed outside its native range.[2] It is a contaminant of alfalfa seed, and grows readily when accidentally introduced to a cultivated field. It has a wide soil tolerance, thriving on saline, sandy, rocky, and dry soils. It does best when growing next to a source of water, such as an irrigation ditch. It is unpalatable to animals and irritating when it invades forage and grazing land.
