Is Morning Glory Poisonous?
As a representative of twining vines, morning glory is loved for its trumpet-shaped flowers and climbing characteristics. However, its toxicity controversy and cultivation methods have always been the focus of attention for gardening enthusiasts. This article will unveil its mystery through multi-dimensional analysis.
In-depth Analysis of Morning Glory Toxicity
Toxin Distribution Characteristics
The entire plant contains tropane alkaloids, with the seeds (black morning glory seeds/white morning glory seeds) being the most toxic. Studies have shown that a single seed can cause adults to experience vomiting, abdominal pain, and other symptoms of poisoning, while children ingesting 5 or more seeds may cause hematuria and nerve damage.
Risks of Home Cultivation
No harm from observation and contact, but caution is needed for pets and children who may mistakenly ingest. Data from the American Poison Control Center shows that morning glory ranks in the top 20 toxic events among gardening plants, and it is recommended that families with young children use hanging cultivation.

Substrate Formula Optimization
The best ratio is decomposed leaf soil: vermiculite: perlite = 5:3:2, with the EC value controlled between 1.2-1.8 mS/cm. Adding 5% bone meal can extend the blooming period by 7-10 days.
Intelligent Water and Fertilizer Management
Using the "dry-wet" method, combined with soil moisture sensors to achieve precise irrigation. Alternating the use of 20-20-20 and 10-30-20 water-soluble fertilizers during the growing period, and applying a 0.2% potassium dihydrogen phosphate solution foliar spray during the flower bud differentiation stage.
Extension of Morning Glory's Ecological Value
Under proper risk management, morning glory can effectively absorb PM2.5 and reduce environmental temperature. Its seeds, as traditional medicine, should only be used under the guidance of a professional physician to demonstrate its medicinal value.
