Spiny rest harrow can also be found growing in Northern Africa and Asia. In these areas, it usually grows on stony hillsides, open pine forests, or chalk and limestone grasslands. The plant prefers sunny meadow climates with dry or slightly moist soil, and will not bloom in the shade. The perennial grows up to two feet (.6 meters) and flowers from early summer to early fall. Its hermaphroditic pink and white flowers are pollinated by bees, and its leaves are sectioned in groups of three.

When growing in certain soils, ononis spinosa creates a symbiotic relationship with bacteria. Together with the plant's roots, the bacteria can form nodules of atmospheric nitrogen to support the plant's health. This nitrogen helps other plants within the vicinity grow as well.
