Why Choose Tropical Plants for Your UK Garden?

Tropical plants aren't just about big, bold leaves and flamboyant colours. Whether you want to make a statement or add subtle, architectural interest, growing tropical plants can:

Give your garden a unique, eye-catching look
Introduce fascinating leaf shapes and textures
Provide colourful blooms throughout summer
Offer new gardening challenges and rewards
Attract beneficial pollinators and wildlife

With the UK's climate gradually becoming milder, many of these exotic plants can thrive with a little care and the right placement. Numerous varieties are surprisingly hardy, while others require just minor protection to survive British winters.

Top Tropical Plants to Grow in a UK Garden

Ready to explore which tropical plants will grow well in a UK garden? Below is our expert selection of the best options, from trees and shrubs to perennials and climbers, that bring a taste of the tropics to even the coldest corners of Britain.

1. Hardy Banana (Musa basjoo)

The Musa basjoo, or Japanese banana, is perhaps the most famous and reliable banana variety for temperate climates. Its huge, paddle-shaped leaves are the very image of the tropics and make a dramatic impact.

Hardiness: Tolerates UK winters with a thick mulch; new growth emerges from the base if stems are killed by frost.
Height: Up to 5m (16ft)
Care: Needs moist, rich soil and shelter from strong winds; water and feed well in summer.
Tip: Trim off tatty leaves after winter and mulch heavily in late autumn.

2. Tree Fern (Dicksonia antarctica and Cyathea cooperi)

Tree ferns add instant prehistoric drama with their lush fronds and striking trunks. The most popular species, Dicksonia antarctica, is surprisingly hardy and perfect for shaded, damp spots.

Hardiness: Down to -10?C with protection for the crown in severe cold.
Height: Up to 4m (13ft) over decades
Care: Keep soil moist and water trunk in dry spells; shelter crown in winter with fleece or straw.
Tip: Underplant with hostas or ferns for a layered, jungle look.

3. Canna Lilies (Canna indica and hybrids)

Bright, bold, and utterly tropical in appearance, Canna lilies offer stunning flowers and flamboyant foliage, ranging from green to deep purple.

Hardiness: Rhizomes survive mild winters or can be lifted and stored frost-free.
Height: 1-2m (3-6ft)
Care: Plant in rich, moist soil in a sunny, sheltered location; feed regularly in the growing season.
Tip: Combine with other large-leaved plants for a dense, tropical border.

4. New Zealand Flax (Phormium tenax and cultivars)

Phormiums are architectural plants with dramatic, sword-shaped leaves in a range of colours. They're ideal for adding structure to the tropical garden.

Hardiness: Most are hardy down to -5?C to -10?C, especially when mature.
Height: 1-3m (3-10ft)
Care: Thrives in sun or part shade in well-drained soil; drought tolerant once established.
Tip: Try 'Yellow Wave' or 'Jester' for striking foliage colour.

5. Tetrapanax papyrifer 'Rex' (Chinese Rice Paper Plant)

This showstopper boasts vast, deeply lobed leaves up to a metre across, instantly creating that jungle vibe. It's fast-growing and surprisingly robust for its looks.

Hardiness: Down to around -10?C; may die back but regrows vigorously.
Height: 3-5m (10-16ft)
Care: Plant in sun or part shade; can tolerate a range of soils. Protect roots from hardest frosts.
Tip: Position at the back of borders for a spectacular canopy effect.

6. Fatsia japonica (Japanese Aralia)

A staple in British exotic gardens, Fatsia japonica offers glossy palmate leaves and is both tough and tolerant of shade--perfect for UK conditions.

Hardiness: Fully hardy in all but the coldest locations.
Height: 2-4m (6-12ft)
Care: Thrives in shade or sun; requires little maintenance once established.
Tip: Excellent for north-facing beds where other exotics would struggle.

7. Cordyline australis (Torbay Palm)

Not a true palm but delivers similar vibes with its spiky, strappy leaves on upright trunks. Cordyline australis is a popular choice for adding vertical interest and a touch of the Mediterranean.

Hardiness: Hardy to around -8?C; mature plants are tougher.
Height: Up to 6m (20ft) over many years
Care: Likes sun and well-draining soil. Protect young plants from severe frost with fleece.
Tip: Plant as a specimen or in groups for greater impact.

8. Ginger Lilies (Hedychium species)

Their exotic, fragrant flowers and lush foliage make ginger lilies a must-have for any ambitious UK tropical garden design.

Hardiness: Most require a mild, sheltered spot or lifting in winter; Hedychium densiflorum is among the hardiest.
Height: 1-2.5m (3-8ft)
Care: Rich, moist soil and a sheltered position work best. Mulch roots in winter for extra protection.
Tip: Their sweet fragrance fills the evening air--plant near seating areas.

9. Bamboo (Fargesia and Phyllostachys species)

Bamboo is sought after for its fast-growing, evergreen screening and an immediate 'tropics' feel. Certain types, like Fargesia (clumping bamboos), are well-suited to UK gardens.

Hardiness: Most are fully hardy.
Height: Varies widely, from 2m to over 8m
Care: Prefers moist, well-drained soil and shelter from drying winds.

Although not strictly tropical, hostas boast bold, broad leaves that fit right in with an exotic garden theme. Pair them with larger-leaved specimens for contrast.

Hardiness: Fully hardy UK-wide.
Height: 30cm-1.5m (1-5ft) depending on variety
Care: Moist, rich soil in partial to full shade. Slug and snail control essential.
Tip: Large-leaved forms like 'Empress Wu' make a real statement!

Designing a UK Tropical Garden: Key Tips

Once you've chosen your favourite tropical plants for UK gardens, you'll want to arrange them to achieve the best visual impact. Here are key design suggestions for a true lush, exotic effect:

Layer your planting: Start with tall canopy plants (tree ferns, bananas), mid-layer shrubs (fatsia, cordyline), and fill below with leafy perennials (hostas, cannas).
Use bold contrasts: Combine dramatic leaf shapes and colours for vibrant, jungle-style planting.
Group in clumps: Plant in groups of odd numbers rather than singly for a natural appearance.
Shelter and microclimate: Use fences, evergreen hedges or buildings to create sheltered spots--warmer microclimates will allow more tropical plant varieties to thrive in the UK.
Add water: A pond or rill provides humidity and fits the tropical theme perfectly.

How to Overwinter Tropical Plants in the UK

While some tropical plants suitable for the UK are surprisingly resilient, others need a little extra protection when cold weather hits.

Caring for your Exotic Plants through Winter

Mulch: A thick layer of bark or straw can protect roots from frost.
Wrap crowns: Use fleece, straw, or purpose-made winter covers for banana, tree fern, and ginger crowns.
Lift tender perennials: Dig up cannas, dahlias, and ginger lilies and store rhizomes in frost-free conditions.
Bring containers indoors: Move potted specimens to a greenhouse, conservatory, or even a light-filled shed or garage.

*Remember: A little protection goes a long way toward ensuring your exotic garden plants come back better than ever next summer!*

Choosing and Caring for Tropical Plants in Containers

Not every UK garden has room for a full jungle border. Many exotic tropical plants also adapt brilliantly to container gardening. This is ideal for patios, courtyards, or for renters.

Choose large pots for bananas, cordylines, or cannas; well-drained compost is essential.
Water and feed more often--containers dry out quickly!
Move pots into shelter for winter, or group together for warmth and easier covering with fleece.
Try: Exotic Brugmansia, scented pelargoniums, or dwarf bananas for stunning displays on decks and balconies.
