Elephant ear plants, also known as Colocasia or Alocasia, are indeed perennials in most cases. However, their ability to come back every year depends on the climate and growing conditions.
In warmer regions like Zone 9 and above, elephant ears are reliable perennials that will regrow each summer. These areas have mild winters and a longer growing season, which allows the plants to thrive and survive throughout the year. I have personally seen elephant ears in my garden come back year after year in a Zone 9 climate.
However, in cooler zones where the winters are harsher and the growing season is shorter, elephant ears may not survive the cold temperatures. In these areas, gardeners often treat them as annuals or dig up the tubers before the first frost. This process involves carefully lifting the plants from the ground, removing excess soil, and storing the tubers in a cool, dry place over winter.
When digging up the tubers, it’s essential to handle them gently to avoid damage. Some gardeners prefer to let the foliage die back naturally before digging up the tubers, while others cut back the leaves to make the process easier. I have personally found that cutting back the foliage before digging up the tubers is more convenient.
Once the tubers are dug up, they should be dried out for a few days to allow any excess moisture to evaporate. After this drying period, you can store the tubers in a container filled with vermiculite, peat moss, or dry sand. It’s crucial to keep them in a cool, dry place like a basement or garage where temperatures remain above freezing but not excessively warm.
Throughout the winter, it’s essential to check on the tubers regularly and discard any that show signs of rot or decay. If stored properly, the tubers should remain dormant until the following spring when they can be replanted in the garden.
In my experience, digging up and storing elephant ear tubers has been successful in colder zones. I have had tubers survive the winter and produce new growth when replanted in the spring. However, it’s important to note that the success rate may vary depending on factors such as the quality of the tubers, the storage conditions, and the specific climate of your region.
While elephant ear plants are perennials in warmer zones, they may not come back every year in cooler climates. However, by digging up and storing the tubers before winter, you can ensure their survival and enjoy these beautiful plants year after year.
