| Toxicity (cats/dogs) | Toxic to pets | Pet-safe |
Which one should you choose?
- Choose Elephant ear — Elephant ear if you prefer its corm-forming clumping perennial habit at 1-2 m tall indoors; 2 m+ outdoors indoors.
- Choose Calathea — Calathea if pets share your home — it is non-toxic to cats and dogs (ASPCA), while Elephant ear is toxic to pets.

Elephant ear vs Calathea — frequently asked questions
Is Elephant ear the same as Calathea?
No — Elephant ear is Colocasia esculenta and Calathea is Calathea (Goeppertia) spp.. Two large patterned tropical-leaf plants — elephant ear (Colocasia) is toxic, calathea is ASPCA non-toxic. The look can be similar, but their light, water and toxicity needs are not interchangeable.
Which is easier to care for, elephant ear or calathea?
Easier comes down to your conditions. Elephant ear wants bright indirect light (just back from a sunny window) and to be watered soil should stay consistently moist during the growing season. Calathea wants medium indirect light (a couple of metres from a window) and watering when the top 1-2 cm of soil is just dry, every 4-7 days. Match the species to the brightest spot you actually have and how often you remember to water — both can be the easier pick for the right home.
Is elephant ear or calathea safer for cats and dogs?
Per the ASPCA, Elephant ear is toxic to pets and Calathea is pet-safe. Calathea is the pet-safer choice.
How big do elephant ear and calathea get indoors?
Elephant ear matures to 1-2 m tall indoors; 2 m+ outdoors, with a corm-forming clumping perennial habit. Calathea reaches 40-60 cm tall and wide, clumping rhizomatous evergreen. Plan for the eventual size, not the size in the nursery pot.
Can elephant ear and calathea live in the same room?
Yes — both can share a room as long as you give each one a spot that matches its light requirement. Elephant ear needs bright indirect light (just back from a sunny window); Calathea needs medium indirect light (a couple of metres from a window). Group them only if their watering and humidity needs are also close, otherwise keep them on different schedules.
