This species is well known as a noxious weed, both in its native range and in areas where it is an introduced and often invasive species. [7] [8] [9] It is naturalized in some areas, and it is recorded as an adventive species in others. [3] It grows in many types of disturbed habitat, such as roadsides, and in cultivated fields.
Weeds may also act as a "living mulch", providing ground cover that reduces moisture loss and prevents erosion.
