Field Bindweed arrived in North America as a contaminant in agricultural and horticultural shipments from Europe and Asia, and it has not looked back. A twining, trailing vine in the morning glory family, it winds through crops, lawns, and disturbed roadsides with tireless efficiency, rooting from fragments of stem and from a root system that can descend several feet into the soil — making eradication genuinely difficult once it is established. It is classified as a noxious weed in 35 states, predominantly across the west and midwest.

The creamy white to pale pink flowers are, it must be said, pretty: small morning glory trumpets that open with the sun and close by afternoon. They have inspired occasional misguided attempts at ornamental use, including hanging baskets, from which the plant has escaped and spread. In moist ground, riparian corridors, and irrigated fields it is especially aggressive. There is no recommended garden use for Convolvulus arvensis. Where it appears, persistent removal — roots and all — is the only management approach that works, and even that requires sustained effort over multiple seasons.
