The Blue Daze plant, scientifically known as Evolvulus glomeratus, is a popular perennial grown widely for its vibrant, true-blue flowers and low-growing, sprawling habit. This plant is favored in warm climates for its ability to create a dense, carpet-like ground cover or to trail beautifully from containers. Its small, silvery, fuzzy leaves and continuous bloom cycle make it a common and attractive addition to home gardens and landscaping. For any homeowner with curious pets or young children, understanding the safety of the plants in their environment is a paramount concern. This article addresses the specific question of whether this common ornamental plant poses a danger to humans or household animals.
Definitive Toxicity Status for Humans and Common Pets
The consensus from major veterinary and horticultural safety organizations classifies the Blue Daze plant as non-toxic to common household pets and humans. Specifically, the American Society for the Prevention of Cruelty to Animals (ASPCA) lists Evolvulus glomeratus as non-toxic to dogs, cats, and horses. This classification means that ingestion of the plant material is not expected to cause severe, life-threatening poisoning or systemic effects in these animals.
The widely accepted classification indicates that the plant lacks the potent toxins that cause severe liver, kidney, or neurological damage. It does not contain the neurotoxins or cardenolides responsible for serious systemic illness. Therefore, a small accidental ingestion is unlikely to result in a veterinary emergency requiring advanced medical intervention. This authoritative status provides reassurance to gardeners and pet owners who want to incorporate this beautiful plant into their household environment.
Understanding the Plant’s Safety Profile
Blue Daze is assigned a non-toxic classification primarily due to the absence of known major toxic compounds, such as harmful alkaloids or glycosides, in its leaves and flowers. The chemical composition of Evolvulus glomeratus is not associated with poisoning syndromes. This inherent lack of harmful agents contributes to its reputation as a safe choice for household gardens and patios.
The term “non-toxic” does not imply the plant is edible or completely benign. Any foreign plant material ingested by a pet or child can still cause a minor reaction, typically involving gastrointestinal upset. This reaction is usually localized and is due to mechanical irritation of the stomach lining, not a systemic poison. Symptoms may include mild, self-limiting vomiting or diarrhea as the body expels the indigestible matter.
Confusion sometimes arises because Evolvulus glomeratus is occasionally referred to by the common name “Dwarf Morning Glory,” which links it to the family Convolvulaceae. Certain true Morning Glory species (Ipomoea spp.) contain seeds that hold lysergic acid alkaloids, which can be toxic. However, Blue Daze is not a true Morning Glory, and it does not possess these same toxic principles, making it a safe alternative to its more problematic namesakes.
Immediate Steps After Suspected Ingestion
A cautious approach is recommended if ingestion is suspected, even with a non-toxic plant. The first step is to remove any remaining plant material from the mouth and the immediate environment. Observe the individual closely for a short period to monitor for any signs of irritation or discomfort.
If a minor reaction occurs, such as mild vomiting or drooling, withhold food and water for a few hours before gradually reintroducing small amounts of water. If symptoms go beyond mild, self-limiting gastrointestinal distress—such as persistent vomiting, lethargy, tremors, or collapse—seek professional advice immediately. Contact your veterinarian, the ASPCA Animal Poison Control Center (1-888-426-4435), or the national Poison Control Hotline (1-800-222-1222 for humans).
When contacting a medical professional, be prepared to provide the specific name of the plant (Evolvulus glomeratus), the amount and part of the plant ingested, and the time of the ingestion. This information allows experts to quickly assess the situation and provide the most appropriate course of action. Do not attempt to induce vomiting unless specifically instructed to do so by a medical or veterinary professional.
