U.S. Weed Information: Convolvulus arvensis is listed in state noxious weed lists for 46 states. State agriculture or natural resource departments; and in: Weeds of Kentucky and adjacent states: a field guide, Weeds of the Northeast, Weeds of Nebraska and the Great Plains, Weeds of the United States and Canada, and Weeds of the West. Plants included here may become weedy or invasive.
Invasive/Noxious Weed Information: Convolvulus arvensis is listed as a Noxious Weed by 22 states including Arizona. Plants included here are invasive or noxious.
Wetland Indicator: No information available.
Threatened/Endangered Information: No information available.

Genus Information: After numerous re-classifications, 9 species in Convolvulus are found in the United States and Canada. 2 species in Arizona. 2 varieties are noted:
Convolvulus arvensis var. arvensis, with broader leaves and
Convolvulus arvensis var. linearifolius with narrower leaves.

Comments: Field Bindweed is a common invasive and noxious weed native to Europe and Asia. At one time California considered this weed as the worst weed in the state. In Arizona it is most troublesome in irrigated areas forming dense mats and crowding out desirable species. Seeds of Field Bindweed are readily eaten by birds.
