Mexican morning glory is native to Central and South America and is cultivated in various regions worldwide. Its introduced range spans across Southeast Asia, the Indian subcontinent, parts of the Middle East, Africa, Europe, Oceania, and other regions of the Americas. The plant's adaptability to different climates has facilitated its spread beyond its original range.

Mexican morning glory has a mild level of toxicity, primarily through seed ingestion. Indole alkaloids in the seeds can cause symptoms such as gastrointestinal disturbances, neurological issues, and hallucinations in humans, cats, and dogs. Prompt veterinary care is essential for pets if ingestion is suspected. The plant’s seeds are particularly toxic and attractive to children and pets.

Mexican morning glory, commonly known as Mexican morning glory, originates from the regions of tropical Central and South America. Its weed-like characteristics come from its highly adaptive nature, allowing it to flourish in various environments. What distinguishes mexican morning glory as a weed is primarily its capability to multiply and spread rapidly via a profuse seed production system. These seeds, when mature, can be indiscriminately scattered by the wind, allowing it to invade new spaces effortlessly. In a garden setting, mexican morning glory can become particularly harmful due to its climbing nature, where it can overcover and suffocate other plants, robbing them of essential sunlight. It can also dominate the nutrient uptake, depriving other plants and causing imbalance in the ecosystem. If you choose to cultivate this plant in your garden, look out for uncontrolled spread and growth overwhelming other plants. Overall, its ability to reproduce quickly, spread over large areas, and choke out other plants contribute to its weed status. Remember, its primary means of spread is through wind dispersal of its seeds.

To manage mexican morning glory effectively, it's crucial to control this plant before it sets seed, which typically happens by late summer into early fall. Here are some steps to control mexican morning glory:
