The 20 best hardy exotic plants for a tropical look in your garden

hardy exotic plants
The ‘tropical’ garden I created in London

When I first started gardening, I wasn’t very interested in the annuals, perennials and grasses that interest me now. Instead, It was the hardy exotic plants I looked to. I was inspired to start gardening by the idea that I could grow bananas, bamboo, palms and tree ferns and create an exotic-looking garden in the small space behind my house in London.

My guide for this venture was the fantastic book Architectural Plants by Christine Shaw, and the source of many of the plants was the magnificent Architectural Plants Nursery in West Sussex.

This was nearly 25 years ago when London winters were colder than they are now, and tropical-look planting was less common in the UK than it is today.

But even so, depending on where you live, creating a tropical paradise in cooler climates can still seem like an impossible horticultural challenge.

Some of the exotics were protected, but this London garden could survive cold winters

However, selecting the right hardy exotic plants can make your tropical garden dream come true. Here is a list of twenty hardy exotic plants that will survive and thrive in less-than-tropical conditions, bringing that sought-after tropical flair to your outdoor space.

I have grown nearly all of these plants in the UK, and whilst some need a bit of protection, it is well worth pushing the boundaries of what is possible if this is the kind of look you are seeking.

1. Trachycarpus fortunei (Chinese Windmill Palm)

This robust palm introduces an unmistakable tropical vibe with its fan-shaped, segmented leaves. Hardy and slow-growing, the Chinese Windmill Palm withstands temperatures well below freezing, making it ideal for creating a tropical look in cooler climates.

Height/Width: Up to 20-40 feet tall and 6-10 feet wide.

Foliage/Flowers: Broad, fan-shaped green leaves. Rarely flowers in cooler climates.

Growing Conditions: Prefers full sun to partial shade with well-draining soil.

2. Musa basjoo (Japanese Banana)

Renowned for its rapid growth and large, lush leaves, the Japanese Banana is the quintessential tropical plant. Despite its delicate appearance, it’s surprisingly hardy. The roots will survive frosts with appropriate mulching, but you will need to protect the trunk over winter if you want that to come through unscathed.

Height/Width: Up to 12-18 feet tall and 6-10 feet wide.

Foliage/Flowers: Large, broad leaves. May produce cream to yellow flowers followed by non-edible bananas in summer if the previous winter was mild.

Growing Conditions: Prefers full sun and moist, well-drained soil.

3. Fatsia japonica (Japanese Aralia)

Fatsia japonica brings drama to any garden with its large, glossy leaves that can lend a lush, tropical touch. It’s exceptionally hardy and likes shade, so can fill those difficult spots.

The leaves will wilt a little when hit by frost. But I have always found that they bounce back. There is always a fresh flush of leaves in spring in any case.

Height/Width: Up to 6-10 feet tall and wide.

Foliage/Flowers: Glossy, deep green, palmate leaves; white flowers in late autumn followed by black berries.

Growing Conditions: Thrives in partial to full shade and moist, well-drained soil.

Cultivars: ‘Spider’s Web’ features speckled white variegation, ‘Variegata’ has leaves edged with cream, and ‘Annelise’ is notable for its yellow and green mottled leaves.

4. Cordyline australis (Cabbage Tree)

Towering and dramatic, Cordyline australis adds height and texture with its sword-shaped leaves and woody trunk. This plant is resilient against wind and can tolerate some degree of frost.

Height/Width: Up to 10-20 feet tall and 5-8 feet wide.

Foliage/Flowers: Long, narrow leaves that can be green, red, or purple; fragrant white flowers in summer.

Growing Conditions: Prefers full sun or partial shade and well-drained soil.

Cultivars: ‘Torbay Dazzler’ sports green and cream striped leaves, ‘Red Star’ flaunts deep red foliage, and ‘Sundance’ is celebrated for its bright yellow leaves.

5. Dicksonia antarctica (Tasmanian Tree Fern)

The Tasmanian (or Woolly) Tree Fern provides an exotic focal point with its sprawling fronds and thick, fibrous trunk. It’s remarkably frost-resistant once established, although it is best to protect the central growing point with some straw in winter.

This prehistoric wonder embodies the essence of exotic planting and became incredibly popular with the Victorian British horticulturalists. So you will often see magnificent large specimens like these in the gardens of aristocratic estates.

Height/Width: Up to 10-15 feet tall and 6-10 feet wide.

Foliage/Flowers: Long, arching green fronds; does not flower.

Growing Conditions: Best in partial shade with consistently moist, fertile soil.

6. Ensete ventricosum ‘Maurelii’ (Red Abyssinian Banana)

For a dramatic splash of colour, the Red Abyssinian Banana’s striking red-tinged leaves are unbeatable.

This plant doesn’t really belong on this list because it won’t tolerate frost. But it can be grown as a fast-growing annual in cooler zones or overwintered indoors.

Height/Width: Up to 8-10 feet tall and wide.

Foliage/Flowers: Broad leaves with a deep red underside and stalk; rarely flowers.

Black Bamboo adds elegance and mystery to any garden, with its sleek black culms and lush green leaves. Like most Phyllostachys, this is a fast-growing bamboo and can form a dense screen. But it should be contained by some kind of root barrier to prevent it from becoming invasive, especially in warm climates and when grown in full sun.

Height/Width: Up to 15-25 feet tall and spreading.

Foliage/Flowers: Dark green leaves; rarely flowers.

Growing Conditions: Thrives in full sun to partial shade, prefers moist, well-drained soil. Needs containment.

Century Plant is celebrated for its sculptural form and large, spiky leaves. This desert plant is surprisingly hardy in temperate climates if protected from winter wet.

An incredible feature of the Agave americana is its flower spike. As you can see from the image below, it produces a huge tree-like structure, which has multiple branches carrying many individual flowers. The plant pays a heavy price for all the energy it puts into producing flowers, as it dies immediately after the flowers have been pollinated. New plants usually grow in its place as a result of the multiple seeds that the plant produces.

A sprawling evergreen succulent perennial, when mature Aloe striatula, can form an expansive cluster of rosettes with spiky silver and grey pointed leaves. During the summer, it produces beautiful clusters of yellow poker-like flowers that are particularly attractive to bees.

It thrives in coarse, well-drained soil and, when the drainage is sharp, it can survive harsh winters. It is root hardy, so if top growth is hit hard by frost, it will usually sprout new growth by late spring. Aloe striatula adds a sculptural element to gardens with its spiky, fleshy leaves. It’s very drought-tolerant and perfect for sunny, dry spots.

Height/Width: Up to 1-2 feet tall and wide.

Each of these plants can contribute uniquely to a garden’s tropical theme while offering resilience and adaptability to less-than-ideal climate conditions.

The secret to keeping these plants alive is to ensure you give them the sun, soil and watering conditions they need. This means you’ll need to group plants with similar needs together, and adapt your soil and other growing conditions where possible.
