Twining or trailing vines with arrowhead leaves and white to pink funnel-shaped flowers. C-descriptions
Plants & habitat
Deep roots and persistent seed make control difficult. Vines overgrow neighboring plants; repeated shoot removal and a site-specific plan are usually needed. N-convolvulus-arvensis C-descriptions
People
This review did not establish human ingestion effects. This is an evidence gap, not proof of safety.
Dogs & cats
Species-specific ingestion effects and exposure thresholds were not established in the reviewed sources. This is an evidence gap, not proof of safety.
Other animals
Cornell reports alkaloids that can cause digestive problems in some livestock. Pet effects and a safe feeding threshold are not established here. K-bindweed
Before taking action
Confirm the scientific name before removing a plant, changing animal access, or choosing treatment. An evidence gap means this review has not resolved the question. It does not mean safe. For listed weeds, consult your county weed program about the requirements for your location; follow the current label for any pesticide. S27
