I’m not a dainty gardener by any means. I love bold, colorful, and unexpected elements in my garden. Each year, my garden looks less and less like Cleveland, Ohio, and more and more like the Seychelles. Tropical plants are my passion, and each year I incorporate more and more of them into my garden. Elephant ears, or Colocasia esculenta give me that tropical look that I’m looking for.
With their rapid growth, gigantic leaves that come in an array of different colors, and ease of growth, Colocasia esculenta will give you a big bang for your buck in creating a tropical feel in your garden!
I started out growing the plain old Colocasia esculenta. This species is actually the taro plant which is widely grown in many tropical regions as a food source.
Taro roots provide a starchy food source for many, but I grow them for their colossal leaves. My goal is for you to be inspired to grow elephant ears in your garden. Your neighbors will be amazed and they are easy to grow!
Years ago, I picked up a packet of Colocasia esculenta at a local garden center and planted them in my garden.
It was an encouraging first encounter because although they are said to be hardy only in zones 8 and above, mine somehow managed to survive our sometimes nasty Ohio winters and returned year after year!
Please note though that my Colocasia esculenta behaved as a perennial in my Ohio garden because they were planted in a protected area and it provided an effective microclimate for them to survive.
Be sure to read my blog post on Pushing Your Hardiness Zone to find out how I accomplished this feat, and others as well!
The clump grew bigger and bigger each year and there was no additional mulch or protection added!
They simply returned as any perennial would on its own. I attribute them surviving our winters in our zone 6 climate because they were planted in a protected corner of our home, close to a concrete pad and brick foundation of the house.
This created a microclimate and helped to defy where this is “supposed” to grow. As shown in the photograph below, it created a lovely pairing with Lady’s Mantle, boxwood, and hydrangea.
One year I had 8 different types of elephant ears in my garden! They are hard to resist and there are so many varieties. I planted the same Colocasia esculenta at our new house, but I dug up the corms and replanted them in the Spring since I didn’t want to risk them freezing.
I planted some in the ground, like the photo below. I love the contrast they provide against the surrounding flowering plants.
I had 3 extra corms that I didn’t have room for in the ground, so I decided to plant them in a 14 inch clay pot. I did not expect them to grow as large as they did in the photo below.
Needless to say, I’ll be planting some in that pot every year. Look how big they grew! And yes, the pot in the picture below is 14 inches in diameter. The large leaf in the middle of the picture is over 2 feet long, and it was close to 2 feet wide.
Planting Elephant Ears
I suppose you probably clicked on this blog post to find out how to grow elephant ears, so let me tell you about the cultural conditions that they like.
I’ve found that elephant ears grow best in partial sun or filtered sunlight. Morning sun works beautifully, but afternoon sun may be a little much sometimes for these plants.
You’ll know if they are upset if the edges of the leaves turn brown. They also like areas protected from high winds.
Watering Elephant Ears
Colocasia esculenta LOVE water. They grow best in consistently moist soil. If you are heavy handed with watering, these are the right plants for you!
In fact, the taro plant is often cultivated for their edible corms in flooded fields. Take a look at the photo below showing a dark leaved variety, growing directly in our old pond!
Whatever you do, do not let this plant go bone dry. Keeping these plants well watered is the most important thing you can do to keep them looking great.
This is one plant that you can “overwater” with profound results! So take out that hose and watering can and go to town.
I will have to add though that you should go light on the water if you are starting out with a bare corm. Wait until the leaves start to grow before increasing the watering.
For a newly planted corm, give it a good watering, but wait until the top of the soil dries out before watering again. As the plant grows and get bigger, you can safely increase the watering.
With the exception of the ones growing in the ground, I water the potted elephant ears daily in the summer.
These plants prefer a loamy soil with a lot of organic matter, but the ones I planted directly into the ground in an amended clay soil are doing just fine!
If you are planting in a pot, any good potting mix will do. Mixing in compost into the potting soil would be very beneficial.
Make sure you regularly fertilize these plants for the best show possible! For ease and convenience, I always order my fertilizers on Amazon so check out my recommendations below:
Elephant ears are heavy feeders and will grow quickly, so be sure to regularly feed them.
When I’m planting them directly into pots, I love mixing in Oscomote right at that time.
This is one of the best fertilizers, in my opinion, for outdoor plants. It is time-release so you can mix it into the potting mix once and it will last for months. I use this product on all my pots outdoors.
I also like to supplement with liquid fertilizers every week or two. My favorite product to use is Neptune’s Harvest fish emulsion and seaweed fertilizer. It is a natural product and results in great growth.
I will also do an occasional application of Miracle-Gro, especially early on in the season, for an extra boost! Don’t skip the fertilizer if you want your elephant ears to grow luxuriantly!
Overwintering Elephant Ears
Elephant ears are easy to overwinter if you live in areas colder than zone 8 like I do. I will dig up the corms, cut most of the stems off, and shake off all the extra soil.
After letting the corms air dry for a couple days, I’ll store them in our heated garage completely buried in Perlite which I purchase in bulk on Amazon.
I follow the same procedure when I overwinter my dahlias. Click HERE to read my blog post on growing dahlias.
You can also store them in dry peat moss if you have that handy. I like to use old plastic pots and will bury the corms completely in perlite, and then place them on a shelf for the winter.
If you don’t have a heated garage, any cool area that stays somewhere in the range of 40F-60F or so will work well.
When Springtime Comes
I’ve learned that these plants sometimes take a long time to start growing after you replant the bare corms.
They will eventually catch up with rapid growth once they start growing leaves, but starting them into growth sometimes takes a very long time!
If you can, I would recommend planting these indoors in the spring, at least 2 months or so before it is warm enough to plant these outside.
This will give you a good head start on the season. Look at the cute little baby elephant ears below!
More Elephant Ears!
I hope you’ve been inspired to grow some Colocasia esculenta in your garden. They come in a variety of colors and all of them are rewarding.
In case you haven’t been inspired, here are some more photos from my garden.
And last but not least, a dark leaved Colocasia from my garden below. I neglected to document the variety, but isn’t it gorgeous? I grew a huge patch of these one year in my garden.
Why not add some Colocasia esculenta in your garden this year? Few plants will have as big of an impact as these delightful plants.
Have you grown any Colocasia in your garden?
