If you have a pool, or a home on Lake Murray, or you just want to feel like you’re on vacation, it’s easy to bring the feel of the tropics home with a variety of plant selections.  Fortunately, our climate typically supports growing and maintaining tropical banana plants as perennials. These exotic beauties thrive on sun and humidity, so our summers are perfect!   We don’t have a long enough growing season to produce fruit on banana plants, however, these tall, tree-like plants with delicate, elongated leaves can be enjoyed throughout the warm weather year after year, with a cut-back and mulch when frost arrives.  Elephant Ear plants, sometimes considered annuals in our area, can be used as a focal point in the landscape, a stand-alone plant, or a “thriller” in a container garden plant grouping.  Many colors are available, accented with beautiful veining, offering a dramatic effect.  If you take the container garden route, it’s possible to overwinter by bringing it inside to provide protection from the cold temperatures.  

There are a variety of species and cultivars of banana plants, and most that we have access to belong to the genus Musa.  Banana plants originated in Southeast Asia near present-day Malaysia and Indonesia. Travelers introduced the plant to Africa sometime in prehistoric times and brought it to South America during the mid-1000s.  While we often hear banana plants referred to as trees, they’re actually large, herbaceous plants. Banana leaves emerge from a corm, which is a swollen, underground stem in a tightly-rolled form. The leaves lead to what looks like a trunk, but the structure is actually a pseudostem and if it were to produce actual bananas, the stem would then be cut away.  Each pseudostem that develops will only produce one time.  It’s not really an issue in this area of the country where fruiting is not likely to occur, but it’s interesting to note and supports the cutting back of the stem(s) in winter. It’s normal procedure for the plant.  Some locals have been known to dig up the banana tree each Fall, cut the leaves off, lay the trunk and roots down, “bury” trunk and roots under heavy mulch in a protected area (crawl space of the house works well), and replant it each Spring.  This technique keeps the trunk from freezing and creates the potential for fruit development over time.

Banana plants are very fast-growing and are not particularly vulnerable to pests.  Mature size varies anywhere from 2 ft. (dwarf varieties) to 15 ft.  They like heavy feeding with a high Nitrogen fertilizer and like to stay moist, but not completely saturated with water. 

Elephant ears, also native to Asia, provide dramatic foliage with their enormous, heart-shaped leaves, ranging from 2-6 ft. long on top of 3-7 ft. stems.  Species Alocasia and Colocasia do well in the Midlands with many varieties and colors available. These tuberous plants can be grown as summer annuals however, Colocasia varieties are often perennial in our agricultural zone. In general, morning sun and afternoon shade are preferred, but if the leaves point up full sun can be tolerated.  Elephant ears prefer fertile, loamy soil that is slightly acidic and they don’t like to dry out.  Keep them wet.  If you’re looking for something to plant around the edge of a pond or in a rain garden, Elephant Ears are perfect for the job.  You may need to dig up the tuber and replant in the spring (after danger of frost) if it is not a type that can hold its own in cold weather.  Bring vulnerable Elephant Ear plants in container gardens into the garage or greenhouse in the winter.  Fertilize regularly with a high Nitrogen fertilizer during the growing season.  If you see aphids, whiteflies, or spider mites, spray an all-purpose plant insecticide to eliminate the little buggers.  See info at the end of the blog for pest control options.  Interesting Fact… Elephant ear is grown as a food crop in much of the tropical world and the traditional Polynesian dish, poi, is made from the tubers. It is, of course, cooked.  Note… The calcium oxalate crystals in the leaves are toxic and very irritating to the mouth (if uncooked), so be sure to keep pets and small children away from Elephant Ears in the garden.

When you can’t get to a tropical paradise, just create one in your own back yard.  Bring drama and interest into your landscape or combine smaller versions in containers with summer annuals.  Pay attention to cold weather characteristics of the different varieties you come across and take the necessary action to overwinter them successfully, or simply plant as annuals.  There are SO many tropical plants in addition to these favorites, so come on out to Wingard’s and check them out.  After you’ve planted your tropical accents, relax and play a little Jimmy Buffett music.  Imagine you’re sitting on a beach somewhere on an island in the Carribean and head on over to Margaritaville.
