Elephant ear plants bring to mind lush, tropical forests, adding drama to both gardens and containers. The most recognized forms have heart- or arrow-shaped leaves (often oversized) with decorative veining, inspiring the common name elephant ears. No plant satisfies the craving for a taste of the tropics like elephant ear plants. Popular in Victorian times, they have enjoyed a rebirth in the recent craze for zone-denying exotic plants.

High drama and bold texture are the signature benefits of showcasing elephant ears in a garden or container. Growing them is simple — they like filtered sun or shade and rich, moist soil. They're grown from tuberous rhizomes and can reach impressive sizes quickly.


Fully hardy in Zones 10 to 11. Elephant ears will only truly thrive in warmer areas similar to their native humid climates of Southeast Asia, and with daytime temperatures of 70 to 85F, and nights no lower than 60F. They can be grown in cooler areas, but will need to be replanted each year.


Most prefer filtered sun or shade, but some tolerate full sun. In general, green types can take higher light levels; darker-leaved ones need more filtered light or shade.


Elephant ears need rich soil that is moist (not saturated), but well-drained. Most don't like wet feet, though a few are tolerant of wet conditions—like the big-leaved colocasias you might see in water gardens. A general rule is big, green elephant ears are practically indestructible and can tolerate variable moisture conditions; dark-leaved types will suffer if over watered and can stay dry for several days.


To prevent disease problems, water in the morning so they go into the night dry. If possible, water from below at the root zone rather than from above, to keep water off the leaves.


They're not heavy feeders. Apply a slow-release fertilizer at planting time, following package directions. If foliage shows yellowing, it’s probably a micronutrient deficiency. A fertilizer with micronutrients can be applied, or sprinkle Epsom salts around the base of each plant on a monthly basis.

Overwintering and cutting back:

In colder zones, the tuberous rhizomes can be dug up and stored over winter. In warmer areas, they can be left in the ground or in their pots.

  • For colder zones that receive frost or freezing temperatures:
    1. Cut back foliage to the ground once it turns brown, usually two to three days after a killing frost
    2. Dig up rhizomes
    3. Allow to dry for a few days
    4. Store in an open container with peat moss or dry potting soil barely covering the rhizome
    5. Keep them cool (45 to 55 degrees) and dry
  • For warmer areas, once the foliage turns brown, cut it back to the ground. Bulbs can stay in the ground or in their pots over winter. Protect from frost by covering the base of the plant with 4 to 12 inches of mulch.


Their rapid growth creates a show even during a short growing season, making them worthy as one-shot annuals of benefit to northern gardeners. But among the 70 or so species and their cultivars, there are small, medium, and large sizes; leaf shapes from wide hearts to slim arrowheads; colors accentuated with bright veining and spots; and textures from slick and glossy to thick and waxy. While their use in gardens has given them their current cachet, many also make good houseplants.

Even when you touch this elephant ear, it’s hard to believe it’s real. Thick, quilted leaves with nubby texture feel like plastic. A smaller alocasia, typically eight to 12 inches tall.

Hardy to Zone 9 outdoors but makes an easy houseplant (or terrarium specimen) since it is slow growing and can take the low light and dry air typical of indoor situations.


  • Add oversized elephant ears to the perennial border for a dramatic focal point. A plant with large green leaves also gives the eye a rest amidst masses of colorful flowers.
  • Alocasias make good companions and dramatic centerpieces in mixed containers, used with other foliage plants and flowering annuals that like filtered sunlight and moist soil. Use one of the larger types in a big pot for a showstopper.
  • Purple-foliaged species combine well with silver, pink and chartreuse plants.
  • Combine elephant ears with other tropical-looking plants like cannas, bananas, variegated tapioca, caladiums, and coleus for a summer jungle garden.
  • An alocasia in a container placed out in the garden can be a movable focal point, and can hide the bare spot left when spring-blooming bulbs go dormant.


Are elephant ear plants poisonous?

Elephant ear plants are poisonous if ingested in large quantities. The plant's leaves and stems contain oxalic acid, which can cause serious illness in children or pets. However, cooking renders the toxins harmless and many cultures have safely eaten them for years (specifically taro root, or Colocasia esculenta). See more Common Poisonous Plants for Dogs and Cats.

Do elephant ear plants bloom?

Yes, they can bloom; however, it is not common or predictable. Some gardeners report blooms (called spathes) in spring after bringing their plants outdoors and fertilizing, while other gardeners never see them bloom. These plants are grown primarily for their tropical foliage.

Are elephant ear plants perennials?

Most are perennials in Zone 9 and warmer, where they will come back each summer. If gardening in cooler zones, you can treat them as annuals or dig up the tubers before the first frost and keep them in a cool, dry place over winter.

When do elephant ear plants sprout?

Elephant ears usually sprout three to eight weeks from planting. Sprouting occurs when the weather begins to warm in spring. They will sprout faster in warmer climates than in cooler climates. To speed up the process, you can start them inside and move them outdoors once it warms up.

Why are my elephant ear plants turning yellow?

If the leaves are turning yellow, it could mean there is a problem. Try changing the amount of sunlight or water the plant gets and possibly apply a fertilizer. Alternatively, the plant may be going dormant for the season. Cut back the yellow leaves and wait for it to return next spring.

Do elephant ears spread?

Some elephant ear plants spread along the ground, while others grow in clumps. Runners will quickly form a large mass of plantings, which can be good or bad. If you’re worried about them spreading out of control, choose a clumping variety.

Can elephant ears grow in full sun?

Full sun is not ideal for most—they grow best in bright but indirect sunlight. Too much sunlight can burn the leaves, while too little sunlight can cause yellowing. There are certain varieties that can tolerate full sun.

Can you plant elephant ear plants in a pot?

Yes, elephant ears can be planted in pots. Since they grow quite large, you’ll want to select a container that is roomy and stable. Container-grown plants can easily be moved inside when cold weather arrives and enjoyed as houseplants.

Why are my elephant ear plants drooping?

Elephant ears may droop because there is a problem. Try adjusting the amount of light or water or applying a fertilizer. Another reason for drooping is that the large leaves become too heavy. Staking can help support the plants and prevent drooping. Plants will also droop if temperatures are too cold for them.
