Did You Know?
1. Elephant ears, also known as Alocasia plants, can tolerate temperatures as low as 50 degrees Fahrenheit (10 degrees Celsius) – much lower than most people realize!
2. They are native to the tropical regions of Southeast Asia, making it surprising that they can withstand colder temperatures.
3. The reason behind this tolerance lies in their ability to go into a state of dormancy during colder seasons, where they conserve energy and reduce their metabolic activity.
4. Elephant ears have a unique adaptation called “elephant-like” ears due to the shape and size of their leaves, which help to keep the plant cool in hot temperatures and minimize water loss.
5. Elephant ears can be grown both indoors and outdoors, with the latter requiring protection or bringing the plant indoors during the winter months in colder climates.
Planting Elephant Ear Bulbs In Spring After Frost
Elephant ears, also known as Alocasia or Colocasia, are exotic plants that add a tropical touch to gardens and landscapes. These plants are native to regions with warm climates and thrive in temperatures above 65ºF. Therefore, it is crucial to plant elephant ear bulbs in the spring, after all signs of frost have disappeared and the soil has reached the desired temperature.
Planting elephant ear bulbs when the temperatures consistently exceed 65ºF ensures optimal conditions for growth. This allows the bulbs to establish themselves before colder weather arrives in the fall. By timing the planting right, gardeners can promote healthy growth and ensure their plants thrive throughout the summer season.
Perennial Elephant Ears And Their Soil Preference
One of the remarkable characteristics of elephant ear plants is their ability to come back year after year. Most varieties of elephant ears are perennial, meaning they will emerge from dormancy and grow again each summer. However, to ensure their longevity and health, it is essential to understand their soil preferences.
- Elephant ears prefer dry soil in the winter, as excessive moisture during the dormant period can lead to bulb rot.
- It is crucial to avoid overwatering during this time and provide adequate drainage.
- Adding organic matter and compost to the soil can improve its quality and help retain moisture during the growing season.
By understanding the importance of soil preferences, gardeners can create an ideal environment for elephant ear plants, promoting their perennial nature and ensuring their continued growth and vigor.
Able To Survive In Zones 8-9 With Foliage Dieback
Elephant ears can survive in regions classified as USDA hardiness zones 8-9. However, it’s important to note that when exposed to colder temperatures, the foliage of these plants will die back. Despite this temporary setback, the bulb remains alive underground and will regrow when the weather warms up again.
If you live in zones 8-9, it is crucial to protect the bulb during cold periods. This can be done by providing a layer of mulch or covering the soil with a thick layer of straw or leaves. These protective measures help insulate the bulb from extreme temperature fluctuations, preventing damage and ensuring its survival.
Gardeners in these zones should also be prepared for the foliage to die back during the winter months. While it may seem disheartening, this is a normal part of the plant’s life cycle and should not cause concern. With proper care and protection, elephant ears will return with their characteristic beauty when the warmer seasons arrive.
- Elephant ears can survive in USDA hardiness zones 8-9.
- The foliage dies back in colder temperatures, but the bulb remains alive.
- Protect the bulb with mulch or a thick layer of straw or leaves during cold periods.
- The foliage dying back is a normal part of the plant’s life cycle.
- Elephant ears will regrow when the warmer seasons come.
Leaving Elephant Ears In Ground In Zones 7-11
For gardeners located in regions classified as USDA hardiness zones 7-11, there is the option of leaving elephant ear bulbs in the ground during the colder months. However, additional precautions must be taken to ensure their survival.
In these zones, it’s crucial to cover and protect the soil where the bulbs are planted during the winter. This can be achieved by providing a thick layer of mulch or using row covers or cloches. These protective measures shield the bulbs from freezing temperatures and provide the necessary insulation to prevent damage.
It’s important to note that while elephant ears can survive in zones 7-11, they are not fully hardy in these regions. Therefore, leaving them in the ground without any protection is risky and may result in bulb damage or death. By taking the necessary steps to protect them, gardeners can enjoy the convenience and beauty of leaving the bulbs in the ground while ensuring their longevity.
Elephant Ears’ Hardiness And Winter Storage Guidelines
When it comes to hardiness, it’s essential to recognize that elephant ears are only fully hardy in USDA hardiness zones 9-11. These regions provide the warm climates that these plants need to thrive without the risk of freezing temperatures.
For gardeners in zones outside of 9-11, it is advisable to dig up the elephant ear bulbs before the temperature drops in the fall. This preemptive action will protect the bulbs from potential damage and allow for storage during the winter months.
To winterize elephant ears, begin by cutting the stems down to approximately 6 inches tall after the first frost. This will reduce the plant’s size and make it easier to handle during storage. To store the tubers, choose a cool and dark place, such as a basement or garage, where temperatures remain consistently above freezing. Place the tubers in a container filled with a mix of peat moss and soil, ensuring they are not directly exposed to light.
By following these guidelines for winter storage, gardeners can protect the bulbs’ viability and ensure a successful regrowth in the following spring.

Frequently Asked Questions
What temperature is too cold for elephant ear?
Elephant ears are not well-suited for cold temperatures, as they prefer warm and humid environments reminiscent of their native Southeast Asia. While they can tolerate cooler temperatures, they start to struggle if the thermometer drops below 50F. Anything lower than this can be considered too cold for the well-being of elephant ears, impeding their growth and potentially causing damage to the plant. Therefore, it is crucial to ensure that elephant ears are kept in a suitable environment where the temperature does not fall below 50F to maintain their thriving condition.
Will elephant ears grow back after freeze?
Elephant ears have a remarkable ability to regrow after a freeze. While the foliage might wither due to the cold, these resilient plants have a tendency to bounce back and flourish during the following summer in regions like the Lower, Coastal, and Tropical South. Therefore, despite encountering harsh conditions, their capacity for rejuvenation ensures that elephant ears will continue to grace these areas with their impressive presence year after year.
Can you keep elephant ears inside during the winter?
Yes, it is possible to keep elephant ears indoors during the winter. By growing them in pots, you can easily bring them inside when the weather gets chilly. Elephant ears can adapt well as houseplants if given the necessary space, light, and attention they need. With proper care, your elephant ears can thrive indoors, adding a unique touch to your home during the winter months.
What is the lowest temperature for Colocasia?
The lowest temperature for Colocasia is around 15 degrees Celsius. This tropical plant thrives in extremely wet conditions or standing water, even during winter. However, if the temperature drops below 15 degrees Celsius, the above-ground parts of the plant will die off, as the leaves require this minimum temperature in order to survive.
