It’s Monday again and I’ve got another plant your horse can’t eat for you. While today’s plant is fairly common it’s not generally on the equine menu. The Elephant Ear is almost too big to eat!

A Little About Elephant Ear

Colocasia is also called Elephant Ear. This is a perennial herb which grows large, arrow-shaped (often variegated) leaves on long stalks. Flowers grow in a spadix with a green/yellow spathe.

How Dangerous Is It?

This plant is unpalatable to equines and not often grown in areas animals have access to. However it contains highly toxic calcium oxalate crystals which can irritate on contact.

All parts of this plant are toxic and can be fatal to equines.
