Elephant ear plants, with their dramatic, oversized foliage, are a popular choice for adding a tropical flair to gardens and indoor spaces. Their lush green leaves create a visually appealing backdrop and evoke a sense of the exotic. However, if you’re considering adding these plants to your landscape, it’s important to understand which animals might find them palatable. Understanding the potential predators of elephant ear plants can help you protect your prized greenery and ensure their healthy growth.
Understanding Elephant Ear Plants: Toxicity and Attractiveness
Elephant ear plants belong to the Colocasia and Alocasia genera, both members of the Araceae family. They are known for their large, heart-shaped or arrow-shaped leaves that resemble the ears of an elephant, hence the name. These plants contain calcium oxalate crystals, which are toxic to both humans and animals if ingested in large quantities.
These crystals are needle-shaped and can cause irritation and burning sensations in the mouth, throat, and stomach. Despite this defense mechanism, some animals are still drawn to the plant’s foliage, either out of curiosity, hunger, or a degree of tolerance to the toxins. The allure of these plants often lies in their abundance and the succulent texture of their leaves, especially when other food sources are scarce.
Factors Influencing Animal Consumption
Several factors can influence whether an animal will attempt to eat elephant ear plants. These include:
- Availability of Alternative Food Sources: When other food sources are scarce, animals are more likely to sample less desirable or even toxic plants.
- Animal’s Dietary Preferences: Some animals are naturally more herbivorous than others and may be more inclined to browse on plants, including elephant ears.
- Animal’s Tolerance to Calcium Oxalate: Different species have varying degrees of tolerance to the calcium oxalate crystals found in elephant ear plants. Some animals may experience only mild irritation, while others may suffer more severe reactions.
- Plant’s Maturity: Younger, more tender leaves may be more appealing to animals than older, tougher leaves.
- Geographic Location: The types of animals that may eat elephant ear plants will vary depending on your geographic location and the local wildlife population.
Common Culprits: Animals Known to Graze on Elephant Ears
While elephant ear plants aren’t a primary food source for most animals, several species have been known to sample or even significantly damage these plants. Knowing your local wildlife is key to understanding potential risks.
Mammals
Several mammals, both large and small, can be potential predators of elephant ear plants. The extent of damage depends on the animal and the availability of other food.
Deer
Deer are notorious for their browsing habits and are capable of causing significant damage to a wide range of plants, including elephant ears. They may be more likely to target these plants during periods of drought or when other food sources are scarce. While the calcium oxalate may deter them somewhat, a hungry deer may still consume enough to cause noticeable damage.
Rabbits
Rabbits are another common garden pest that may nibble on elephant ear plants, particularly young, tender shoots. They can quickly decimate smaller plants and can also damage larger ones by chewing on the leaves and stems. They are more likely to consume elephant ears if other, more palatable plants are not available.
Voles and Other Rodents
Voles and other rodents, such as mice and rats, may also occasionally feed on elephant ear plants, especially the underground tubers and roots. This can weaken the plant and make it more susceptible to disease.

Are elephant ear plants toxic to animals?
Elephant ear plants, particularly their leaves and stems, contain calcium oxalate crystals. These crystals can cause significant irritation and burning sensations in the mouth, throat, and stomach if ingested. While not typically fatal, ingestion can lead to drooling, vomiting, and difficulty swallowing for animals, including pets.
Because of this potential toxicity, it’s essential to exercise caution when growing elephant ear plants in environments where animals have access to them. Keep them out of reach, or consider alternative, non-toxic plants if you have pets prone to chewing on greenery. Prompt veterinary attention is crucial if you suspect your animal has ingested any part of an elephant ear plant.
What animals commonly eat elephant ear plants in the wild?
In their native tropical and subtropical environments, elephant ear plants are sometimes consumed by certain invertebrates and, less frequently, some larger herbivores. Snails and slugs, drawn to the moist foliage, may nibble on the leaves, causing superficial damage. Deer, when other food sources are scarce, might sample the plants, but they are not a preferred food source due to the plant’s inherent toxicity.
Invasive species, or wildlife in regions where elephant ear plants are introduced, can also develop a taste for them, though this is usually not the primary food source. The specific animals that consume elephant ear plants vary depending on the geographic location and the availability of other vegetation. Overall, however, because of their toxicity, elephant ears are not a common or desirable food source for most wild animals.
Do squirrels eat elephant ear plants?
Squirrels are generally not known to consume elephant ear plants as a primary food source. Squirrels typically prefer nuts, seeds, fruits, and other readily available sources of carbohydrates and protein. While they might occasionally nibble on the leaves out of curiosity or during periods of extreme food scarcity, it is not a regular occurrence.
If squirrels are observed damaging elephant ear plants, it is often because they are searching for insects or digging for buried nuts nearby, rather than specifically targeting the plant itself for sustenance. Other factors, such as thirst during dry weather, may also prompt squirrels to sample foliage, although elephant ear plants are not a hydrating food source due to their calcium oxalate crystals.
Will my dog be poisoned if it eats elephant ear?
Yes, your dog can experience discomfort and symptoms of poisoning if it ingests elephant ear plants. The calcium oxalate crystals present in the plant can cause significant irritation to the mouth, tongue, and throat. This can lead to drooling, pawing at the mouth, vomiting, and difficulty swallowing.
While typically not fatal, ingesting elephant ear plants requires immediate veterinary attention. Your veterinarian can administer treatments to alleviate the discomfort and prevent further complications. Keeping elephant ear plants out of reach of your dog is the best way to prevent potential poisoning.
How can I protect my elephant ear plants from being eaten by pests?
