Peganum thrives in dry steeps where grazing is extensive and at dry
places. It widely grows in waste lands as weed.
It can grow in saline soil but prefers acidic, neutral, alkaline, light and well drained soils. Since it grows on the waste lands sunlight is most important for its growth.
The seeds get ripe in September and the flowers are considered to be hermaphrodite.
It widely grows in USA and spread to Arizona, California, Montana, Nevada, oregano and Texas.
Peganum seeds capsules and root are used.
