Surprising Tropical Plants That Thrive in the UK Climate
Are you dreaming of a lush, exotic oasis in your own backyard? Many believe that the cool, frequently damp UK weather limits gardeners to traditional, climate-hardy plants. But what if we told you that a vibrant, tropical paradise can be within your reach--even in the temperate British climate? Read on to discover surprising tropical plants that thrive in the UK climate and learn how to transform your garden into a verdant retreat filled with exotic beauty.
Can Tropical Plants Really Survive in the UK?
The idea of growing tropical plants in the UK seems unlikely at first. With cool winters, unpredictable rain, and a lack of blazing sun, the British Isles hardly seem an ideal environment for exotic, sun-loving species. However, thanks to the moderating influence of the Gulf Stream and increasingly mild winters, certain tropical and sub-tropical plants can not only survive but thrive outdoors--even in surprising locations as far north as Scotland.
- Microclimates: Urban gardens, south-facing walls, and sheltered courtyards can create unique pockets where exotic plants flourish.
- Plant Selection: Many "tropical" plants hail from high-altitude or subtropical regions and are surprisingly cold-tolerant.
- Changing Climate: Warmer winters over the past decades have expanded possibilities for daring British gardeners.
Top Surprising Tropical Plants That Flourish in the UK
Now that you know it's possible, let's explore an array of exotic plants you can grow in your UK garden--plants that evoke distant rainforests, sun-laden islands, and lush jungles.
1. Hardy Bananas (Musa basjoo)
The hardy banana plant is one of the most astonishing tropical plants that thrive in the UK. Native to Japan, Musa basjoo boasts dramatic architectural leaves and can grow up to 5 metres (16 feet) tall in ideal conditions. While its fruit is rarely edible in the UK, the plant's presence creates a true rainforest vibe.
- Frost tolerant down to -10?C with mulch protection
- Fast-growing, with large, paddle-shaped leaves
- Best in sheltered, sunny sites with moist, well-drained soil
2. Trachycarpus Fortunei--The Chusan or Windmill Palm
Among the unexpected tropical palms that survive in Britain, Trachycarpus fortunei is a superstar. With its fan-shaped leaves and rough trunk, it's a classic "palm tree" lookalike that's hardy to at least -15?C.
- Perfect for dramatic focal points in containers or borders
- Thrives in partial shade to full sun
- Wind and frost resistant: essential for unpredictable UK weather
3. Cordyline Australis--The Cabbage Palm
Instantly recognisable with its slender trunk and spiky leaves, Cordyline australis brings a touch of the Antipodes to UK gardens. It's often planted along the south and west coasts for coastal drama--and it's incredibly resilient.
- Tolerates salty winds and urban pollution
- Survives temperatures down to -8?C once established
- Great for garden borders, driveways, and seaside gardens
4. Tetrapanax Papyrifer--The Rice Paper Plant
Seeking impact? The gigantic leaves of Tetrapanax papyrifer lend a bold, tropical aesthetic to gardens. This striking shrub is becoming a favourite among innovative British gardeners embracing a "jungle style."
- Huge, deeply lobed leaves up to 1 metre across
- Prefers partial shade and protection from cold winds
- Survives to about -10?C
5. Fatsia Japonica--Japanese Aralia
For those seeking a tropical evergreen, Fatsia japonica is unmatched. Its glossy, hand-shaped leaves add year-round jungle ambience--perfect for shadier corners and courtyards.
- Extremely shade tolerant
- Hardy to -15?C, making it one of the toughest exotics
- Produces exotic white flowers and berries in autumn
6. Tree Ferns (Dicksonia antarctica & Cyathea spp.)
Ferns may be familiar, but tree ferns surprise with their ancient beauty. The Australian Dicksonia antarctica is the hardiest, forming lush, arching fronds atop rugged trunks.
- Survives most UK winters with trunk protection
- Perfect underplanting for shaded, humid spots
- Adds instant prehistoric or tropical impact
7. Exotic Gingers--Hedychium Species
Many garden gingers, typically from the Himalayas, thrive in the UK climate. Hedychium varieties like "Tara" or "Gardnerianum" bring bold foliage and fragrant, vibrant flowers in late summer.
- Hardy to -5?C or lower with winter mulch
- Moist, fertile soils in partial or dappled shade preferred
- Ideal for adding colour to tropical-style plantings
8. Gunnera manicata--The Giant Rhubarb
If you want a focal point with true rainforest scale, Gunnera manicata is unbeatable. Its colossal leaves can easily surpass 2 metres wide, creating a jaw-dropping jungle effect near ponds or streams.
- Needs abundant moisture and humus-rich soil
- Protect crowns in winter, especially in cold regions
- Provides shelter for amphibians and wildlife
9. Yucca--Desert Drama in the UK
Not all tropical-style plants need high humidity. Yucca species such as Yucca gloriosa and Yucca filamentosa thrive in dry, sunny UK gardens, offering an architectural, spiky look reminiscent of arid landscapes.
- Tolerates drought and poor soils
- Survives down to -15?C
- Magnificent panicles of white flowers in summer
10. Canna Lilies
Canna lilies provide a blaze of hot colours and bold foliage right through summer until autumn. While originating from subtropical America and Asia, they're surprisingly reliable in the UK--especially along the south coast.
- Lift and store tubers overwinter in very cold areas
- Give plenty of water and feed for luxuriant growth
- Mix with dahlias and bananas for truly tropical borders
Expert Tips for Growing Tropical Plants in the UK
Success with exotic plants in the UK climate depends on a few essential care tips. Here's how you can enjoy a low-maintenance tropical effect, even in unpredictable British weather:
- Choose the right site: South or west-facing gardens offer most light and warmth. Shelter from cold, drying winds using fences or hedges.
- Improve drainage: Many tropical species hate waterlogged roots. Incorporate grit, compost, or raised beds for better drainage.
- Mulch and protect in winter: A layer of bark or fleece, and covering crowns of tender plants, can make all the difference during frosty spells.
- Feed generously: Exotic plants are usually fast growers and benefit from rich, moisture-retentive soils and regular feeds.
- Group for humidity: Positioning tropical plants together helps raise local humidity and shelter tender species within a microclimate.
- Experiment!: Each garden is unique, and new cultivars are constantly appearing. Don't be afraid to try unusual plants.

Frequently Asked Questions About Tropical Plants in the UK
Which tropical plant is easiest to grow in the UK?
Fatsia japonica is often the most reliable option for beginners, thriving in shade and requiring minimal protection. Musa basjoo and Trachycarpus fortunei are also good choices for creating instant jungle atmosphere.
Can I grow tropical fruit in the UK?
Some small fruits, such as hardy kiwi (Actinidia arguta) or certain figs, will ripen in a mild UK summer. True tropical fruits like mangoes or pineapples need year-round heat and are best grown under glass.
Do tropical plants survive UK winters?
Many cold-hardy exotic plants survive UK winters with little intervention, especially in sheltered or urban areas. For tender plants, mulching, fleece wrapping, or moving pots under cover helps ensure survival.
Will my tropical garden attract pests?
Most exotic plants in the UK have relatively few pests. Slugs and snails can trouble young shoots or tender foliage, but regular monitoring and wildlife-friendly deterrents keep problems minimal.
How do I feed tropical garden plants?
Use a balanced, slow-release fertiliser in spring, followed by regular liquid feeding through the summer. High-potassium fertiliser encourages blooming in cannas, gingers, and bananas.
