Morning glories, with their vibrant trumpet-shaped flowers, are a beloved sight in many gardens. But lurking beneath their enchanting beauty is a question many gardeners and curious onlookers have: are morning glories poisonous? The short answer is: yes, parts of the morning glory plant are poisonous. This article delves into the specifics to help you understand the risks and how to handle these plants safely.

Understanding the Toxicity of Morning Glories

Several species of morning glory contain tropane alkaloids, specifically l-lysergic acid amide (LSA). LSA is a hallucinogenic compound similar to LSD, but considerably less potent. The concentration of these alkaloids varies depending on the species and growing conditions. However, even small amounts can cause adverse effects, especially in children and pets.

Which Parts Are Poisonous?

All parts of the morning glory plant contain these toxic compounds to some degree. However, the seeds are by far the most concentrated source of LSA. The leaves and stems also contain alkaloids, but in much lower quantities. Therefore, ingestion of the seeds poses the greatest risk.

Harmful Compounds in Morning Glories

The primary toxic compound in morning glories is LSA, as mentioned previously. However, other alkaloids may also contribute to the plant’s toxicity. The exact composition and concentration vary between species, adding complexity to assessing the risk.

Symptoms of Morning Glory Poisoning

Symptoms of morning glory poisoning can vary in severity depending on factors such as the amount ingested, the species of morning glory, and the individual's sensitivity. Symptoms can appear within 30 minutes to several hours after ingestion and may include:

Gastrointestinal Issues: Nausea, vomiting, diarrhea, abdominal cramps.
Neurological Effects: Drowsiness, confusion, hallucinations, dilated pupils, increased heart rate, elevated blood pressure.
Other Symptoms: Tremors, dizziness, weakness, difficulty breathing (in severe cases).

Note: In rare cases, severe morning glory poisoning can lead to seizures, coma, and even death, particularly if a large quantity of seeds is consumed.

What to Do If Morning Glory Poisoning is Suspected

If you suspect morning glory poisoning, immediate action is crucial.

Call for help: Contact your local poison control center or emergency medical services immediately. Provide them with information about the plant ingested, the amount consumed, and the person's symptoms.
Do not induce vomiting: Unless specifically instructed by medical professionals, do not induce vomiting. This can cause further harm.
Support the individual: Keep the person calm and comfortable. Monitor their breathing and vital signs until medical help arrives.
Gather information: If possible, collect a sample of the plant material for identification purposes.

Safe Handling and Garden Practices

While morning glories are poisonous, you can still safely enjoy them in your garden. Here are some preventative measures:

Educate children and pets: Teach children and pets to never eat any part of the plant.
Wear gloves: Wear gloves when handling the plants, especially when pruning or deadheading. This helps prevent skin irritation and accidental ingestion.
Supervise children and pets: Carefully supervise children and pets in areas where morning glories are grown.
Consider alternatives: Explore alternative flowering vines that are not toxic if you are concerned about safety.
