Best Tropical Plants for Southern Landscapes: Beauty and Function Together

The South Is the Only Place in the Contiguous United States Where True Tropicals Thrive Outdoors

Gardeners in most of the country can only dream about growing tropicals outdoors. In Florida, the Gulf Coast, and across zones 9 through 11, many of the most spectacular and productive tropical plants on earth can grow right in your front and back yard without a greenhouse. Combining that beauty with actual food production creates landscapes that look like paradise and feed your family at the same time.

Heliconia: Dramatic, Bold, and Low Maintenance

Heliconia is a tropical plant group that produces some of the most dramatic flowers on the planet, the lobster claw and parrot flower forms that look like something out of a jungle dream. They are rhizomatous plants that spread slowly from underground stems and produce large paddle like leaves topped with incredible flower structures in red, orange, yellow, and combinations of all three.

In zones 10 and 11 heliconias are perennial and essentially permanent once established. They thrive in full sun to light shade, need consistent moisture, and produce flowers that attract hummingbirds and are spectacular as cut flowers. Some species are edible, with flower bracts used in tropical cooking, though they are grown primarily for their ornamental impact in most Southern gardens.

Taro and Elephant Ears: Bold Structure With Edible Roots

Colocasia esculenta, the edible taro, is one of the most striking tropical plants you can grow in a Southern landscape. The giant heart shaped leaves in deep green or dramatic purple black create an immediate tropical effect. In zones 9 through 11 they grow as perennials, returning from large underground corms each year. The corms are edible and are the basis of poi and many other tropical dishes.

Alocasia varieties, the upright elephant ears, add architectural drama to any tropical garden. Many varieties produce striking leaf patterns and colors. While less commonly eaten than taro, they share the same powerful tropical presence and thrive in the South's warm humid conditions.

Bird of Paradise: An Icon That Thrives in Southern Heat

Strelitzia reginae, the classic Bird of Paradise, grows beautifully in zones 9b through 11 and produces its iconic orange and blue flowers repeatedly through the growing season. This plant has incredible drought tolerance once established and tolerates the kind of intense sun that stresses many other ornamentals. Giant Bird of Paradise, Strelitzia nicolai, grows into a multi trunk tree form reaching fifteen to twenty feet and creates an instant tropical canopy effect.

Cassava: The Ultimate Dual Purpose Tropical

Cassava deserves more recognition in Southern food landscapes. It grows into a shrubby plant six to ten feet tall with deeply lobed tropical leaves that are genuinely beautiful in the landscape. The large starchy roots are one of the world's most important food crops. In zones 9 through 11 cassava grows as a perennial crop that can be harvested after twelve to eighteen months. The roots can be boiled, fried, or ground into flour. The leaves are also edible when cooked and used in African and Caribbean cooking.

Passionfruit Vine: Flowers, Fruit, and Wildlife

Passion vine is one of the most productive and beautiful tropical vines available to Southern gardeners. The flowers are extraordinary, intricate purple and white structures that seem to belong in a botanical illustration. In zones 9 through 11 the native and near native passion vine varieties produce edible fruits that wildlife loves and that make excellent fresh eating and juice.

Maypop, the native Eastern North American passion vine, is cold hardy into zone 6 and produces excellent tasting fruits while also being an important larval host plant for several native butterfly species. Tropical passionfruit varieties produce larger commercial type fruits but are cold sensitive and perform best in zones 10 and 11.

Gingers: Edible, Beautiful, and Fragrant

The ginger family contains dozens of species that thrive in Southern gardens. Beyond the culinary ginger and turmeric covered elsewhere, the ornamental gingers like torch ginger, shell ginger, and butterfly ginger create spectacular landscape effects while contributing edible flowers, roots, and leaves to the kitchen. Shell ginger is one of the most cold hardy gingers available, surviving into zone 8b, and its pink and white flowers are literally edible and delicious used in salads and drinks.

Pitaya: Dragon Fruit in Your Southern Landscape

Dragon fruit cactus, with its climbing stems and enormous white night blooming flowers, is one of the most spectacular and eye catching plants in any tropical garden. The fruits are edible and increasingly popular. In zones 10 and 11 dragon fruit grows vigorously on fences, posts, and structures. It is drought tolerant, needs minimal care once established, and produces an exotic crop that delights everyone who encounters it.
