White morning-glory is native to North America and has been introduced to various regions including parts of Asia, Europe, and the Caribbean. Its successful establishment outside its original range has led the species to adapt to a diversity of climates within these broad geographical expanses.

The seeds of white morning-glory can cause serious illness when ingested by humans, cats, and dogs. Symptoms of poisoning include confusion, dizziness, sweating, and vomiting. Cats may show signs of distress, while dogs may experience vomiting, diarrhea, and abdominal pain. Immediate veterinary care is essential if any part of white morning-glory is consumed.

White morning-glory is native to North America and has been frequently cultivated for ornamental purposes. It is not listed as invasive at the state or federal level in the United States. It grows in disturbed areas such as along streams, ditches, and roads. White morning-glory also grows by sprawling stems that can smother other vegetation. These characteristics can allow it to become weedy in some contexts, including agricultural fields. They also act as alternative hosts for some agricultural pests. Repeated application of herbicides can effectively control white morning-glory. Plants can also be hand-pulled, dug from the roots, or covered with thick mulch.

The best time to manage white morning-glory infestations is early spring through fall. White morning-glory should ideally be eliminated before it matures to prevent it from spreading seeds. Here are some methods to control this weed:
