Banana plants bring bold, tropical flair to any garden with their huge, paddle-shaped leaves. The Musa basjoo, also known as the Japanese Banana, is particularly hardy and can survive temperatures down to -10?C with proper mulching. Alternatively, Ensete ventricosum 'Maurelii' offers striking red-tinted foliage.

Sun and shelter: Full sun to partial shade; protect from strong winds.
Soil: Moist, rich, well-drained.
Care tip: Mulch crowns in winter to protect from frost and cut dead leaves in spring.

Famed for their lush, almost tropical leaves and fiery blooms in reds, oranges, and yellows, cannas are showstopping summer perennials. They thrive in the UK if given plenty of moisture and shelter.

Sunlight: Full sun
Soil: Fertile, moist but well-drained
Care tip: Lift tubers after the first frost and store indoors over winter in colder areas, or choose hardier varieties.

3. Tetrapanax papyrifer 'Rex' (Rice paper plant)

For creating instant jungle drama, few plants rival the Rice paper plant. Its vast, deeply-lobed leaves can span a metre or more, lending a prehistoric vibe to your borders.

How to Create a Successful Exotic Garden in the UK

Transforming your plot into an eye-catching exotic garden in the UK involves more than choosing unusual plants. It's about clever planting, creative design, and weather-proofing your investments. Here's how:

Choose Your Microclimate

Many exotic species thrive in warmer, protected spots. To give your rare and tropical-looking plants the best start:

Use walls, fences, or evergreen shrubs to create windbreaks and retain warmth
South- and west-facing gardens receive the most sun and warmth
Plant alongside patios or in inner courtyards for an extra heat boost

Soil and Drainage

Most exotic plants detest waterlogged roots. Make sure your soil is well-drained. You can:

Dig in grit, sand, or organic compost to improve drainage
Grow more tender specimens in large pots or raised beds for better drainage and easier winter storage

Moisture and Humidity

A lush, exotic look often means plants with high moisture needs. Keep them thriving by:

Watering deeply during dry spells
Mulching around roots to retain moisture
Misting leaves in very hot or dry weather

Winter Protection for Exotic Plants

Many eye-catching plant species are surprisingly hardy, but UK winters can still cause problems. Here are essential steps to protect your exotic investment:

Move pots undercover: Place in a greenhouse, conservatory, or shed
Apply deep mulch: Use bark chips, straw, or compost around roots
Wrap stems/trunks: Use horticultural fleece or bubble wrap for cold-sensitive species
Cut back and dry tubers: Store tender bulbs (like canna, ginger lily) in a cool, frost-free place

More Exotic Plants to Experiment With

The UK's mild, temperate regions--especially in the South and coastal areas--support even more unusual species than you might imagine. Here's a further selection of unique, exotic plants to try in your garden:

Use Layers and Bold Foliage

Large leaves: Bananas, tetrapanax, colocasia
Fine foliage: Bamboo, ornamental grasses, papyrus
Vertical accents: Hardy palms, cordylines, yuccas

Include Vibrant Flowers

Bright blooms: Cannas, ginger lilies, calla lilies, dahlias
Unusual shapes: Passion flower, echium, protea (under cover)

Add Water Features and Decorative Elements

Mulch with bark or gravel for a finished, exotic look
