The most common method of preparation is boiling or steaming the tubers or leaves, which can help break down the calcium oxalate crystals and make the plant safe to eat.

However, it’s essential to note that Elephant Ear should not be eaten raw, as the plant’s toxic compounds can cause serious health issues if ingested in large amounts.
Can I grow Elephant Ear in my garden?
Yes, Elephant Ear can be grown in your garden, provided you live in a warm and humid climate with plenty of sunlight. The plant prefers well-draining soil and full sun to partial shade, making it an ideal crop for tropical and subtropical regions. However, it’s essential to note that Elephant Ear is a sensitive plant that requires careful handling and maintenance, as it can be susceptible to pests and diseases.
To grow Elephant Ear, you can purchase tubers or seeds from a reputable supplier and plant them in your garden during the spring or summer months.

Can I feed Elephant Ear to my pets?
