Field bindweed, Convolvulus arvensis, is a native of Eurasia and was first documented in California in 1884 when it was collected in San Diego. By the first quarter of the twentieth century, field bindweed was proclaimed the worst weed in California and many of the western states. Field bindweed has been given many names including perennial morning glory, creeping jenny, bellbine, sheep-bine, and corn-bind.
