No
matter where you go this summer the tropical look is hot,
and one of the key ingredients to this Caribbean-style
garden is the elephant ear.

The
Black Magic, with its dark purple leaves,
is one of the most sought-after elephant
ear varieties. Grow elephant ears with
other coarse-textured plants like bananas,
gingers and cannas, such as the Tropicanna
pictured here.

With
leaves that defy logic in size and proportion to other
plants, it's not hard to see why this plant is so loved by
Southern gardeners. It is not uncommon to see 6-foot-tall
plants with 3-foot leaves on petioles reaching 4
feet.
As
they have done with other popular plants, producers are
striving to bring us more varieties than we even knew
existed. I'll talk about these later.
Select
a site with morning sun and afternoon shade, although I am
seeing more and more fine plantings in full sun where
providing adequate moisture is not a problem. The soil
should be fertile and well drained, especially for winter
survival.
If
your soil is tight and heavy like mine, incorporate 3 to 4
inches of organic matter for good aeration and drainage. Or
try planting on raised beds like the commercial landscapers
do.
While
preparing your bed, work in a slow-release pre-plant
fertilizer like a 12-6-6 with minor nutrients. Use about 2
pounds per 100 square feet of bed space. Most gardeners buy
the giant-sized bulbs, but more and more container-grown
plants are being sold. Be sure to plant the bulbs so that
the top of the bulb is 2 inches below the soil. If you are
planting container-grown plants, set them at the same depth
they are growing in the container.
Feed
your elephant ears monthly with light applications of the
fertilizer, and keep them well mulched. If you have an
established clump, start feeding with the emergence of new
growth in the spring. These are really low-maintenance
plants: just remove tattered or unattractive leaves to keep
them looking their best.
Though
plants normally return even into zone 7, the tubers can be
dug easily for winter protection. Let them dry for a couple
of days, and then remove the foliage. Place them in dry peat
and store in a cool, dry place.
Grow
elephant ears with other coarse-textured plants like
bananas, cannas and gingers. They combine well with
ornamental grasses and can work with almost any other garden
flower. Use them around the pool for a lush, resort-like
atmosphere.
In
many parts of the world, this plant is a starch substitute
with names like poi and dasheen. You can even buy pancake
mixes via the Internet. I'll take a loaded baked
potato!
As
I mentioned earlier, many varieties of elephant ears are
available. Mostly we find varieties of the Colocasia
esculenta. I call these the droopy type. The giant-sized,
green-leafed form is the most common.
One
of my favorite selections is sold under the name of
Illustris or Antiquorum. Its leaves are not quite as large
and have dark burgundy to black in between the veins. The
Black Magic, with its dark purple leaves, is the most
sought-after.
The
elephant that I call upright is Alocasia macrorrhiza. I
recently saw a wonderful established clump of these in Pine
Bluff, Ark. These are available in typical green, variegated
Variegata, and burgundy to purple forms called Metallica,
Rubra and Nigra.
One
really exotic specimen that I waited to try until this year
is the African Mask. Botanically speaking, it is Alocasia x
amazonica. It is small in comparison, but highly variegated
and glossy. Though not as cold-hardy as some, it is
relishing our Mississippi heat and humidity. I have mine
growing in morning sun and afternoon shade beside a Japanese
fiber banana and canna.
Going
to the islands may not be possible, but thanks to plants
like elephant ears, our gardens can look like we live there.
It's not too late for you to plant them.
