Introduction To Elephant Ears Plants
Elephant ears, also known as Colocasia, Alocasia, and Xanthosoma, are a group of tropical perennial plants known for their large, heart-shaped leaves. These plants are native to tropical regions such as Asia, Indonesia, Malaysia, New Guinea, Australia, the Pacific Islands, and tropical America. They are cultivated for both their culinary and ornamental characteristics.
One of the most widely grown species of elephant ears is Colocasia esculenta, also known as taro. It has over 200 different cultivars selected for their culinary or ornamental qualities. These plants can grow up to 3 feet long and 2 feet wide in their native habitats, although they tend to be smaller when grown as seasonal plants.
Important: While the leaves of these plants are edible, they contain skin-irritant calcium oxalate crystals and must be cooked before consumption.
Elephant ears are also known to produce inflorescences with a white to yellow or light green spathe surrounding the spadix. However, it’s worth noting that flowers are not common in the Midwest.

Growing Elephant Ears Outdoors
Elephant ears thrive when grown outdoors in warm climates. In zones 9-11, they can be grown year-round as perennial plants. However, in cooler areas (zones 3-8), they are typically grown as annuals and should be planted in the spring after the danger of frost has passed.
To grow elephant ears outdoors, start by planting the tubers when the soil temperature is at least 65ºF. Plant them pointy side up about 1 inch below the soil surface. The tubers may take a month or more to sprout, so they should be watered sparingly during this time.
It is important to provide elephant ears with consistent moisture throughout the summer. Regular watering is needed, especially during hot and dry periods. Additionally, these plants can benefit from the application of liquid fertilizer every 2-3 weeks to ensure healthy growth and vibrant foliage.
Elephant ears can be planted in various outdoor spaces, including gardens, container plantings, patios, decks, next to walls or fences, and even in entryways to add a tropical touch. They can also be used for screening purposes and as indoor houseplants.
Caring For Elephant Ears Indoors
Elephant ears can be grown both outdoors and indoors, with proper care. When cultivating them as houseplants, it is important to provide the right environment for their thriving.
To care for elephant ears indoors:
- Start by selecting a large bulb or rooted plant for larger foliage.
- Place the plant in a warm and brightly lit location.
- Elephant ears prefer bright light but should be protected from direct sunlight, as it can scorch the leaves.
Maintain a consistent indoor temperature, ideally around room temperature. During the semi-dormant period, elephant ears should be kept slightly dry, watering only when the soil has dried out. In the spring, resume regular watering and fertilizing to promote growth and maintain overall health.
It is recommended to bring elephant ear plants indoors before temperatures drop to the 30s. These plants are sensitive to colder temperatures, and frost can damage or kill them. To ensure their vitality during winter, cut back the foliage and keep the plants at room temperature with bright light.
Remember, by following these guidelines, you can successfully grow elephant ears indoors and enjoy their lush foliage all year round.
Tips For Planting And Maintaining Elephant Ears
To successfully plant and maintain elephant ears, consider the following tips:
-
When planting elephant ear tubers, choose a location with rich, well-drained soil. If the soil needs improvement, incorporate compost or topsoil before planting to provide the plants with optimal growing conditions.
-
Elephant ears require consistent moisture, especially during the summer months. Regular watering is essential, particularly during dry spells. Mulching around the plants can help retain moisture and suppress weed growth.
-
Fertilize elephant ears every 2-3 weeks with a liquid fertilizer to promote healthy growth and vibrant foliage. This is particularly important for plants grown in containers, as they may require more frequent feeding due to nutrient leaching.
-
Remove older leaves as they yellow or become unsightly to maintain the plant’s appearance. This also helps redirect energy to new leaf production.
-
In colder regions, where elephant ears are grown as annuals, dig up the tubers before temperatures drop below 40°F. Brush off excess soil and allow the tubers to dry for a few days. Store them in a cool, dry place indoors and replant them in the following spring after the danger of frost has passed.
