Choosing the Right Tropical Plants for a British Garden
Transforming your British garden into an exotic paradise is no longer just an ambition for those with greenhouses or expert horticultural knowledge. With increased access to hardy tropical plants, improved cultivars, and creative landscaping techniques, introducing a touch of the tropics to your British garden has never been easier--or more rewarding!
Why Choose Tropical Plants for a British Garden?
Traditionally, the British climate--temperate and famously unpredictable--seems unfriendly to truly tropical flora. However, the appeal of lush, architectural foliage, bold colors, and striking forms is irresistible to many gardeners. Thankfully, a wide range of tropical and subtropical plants now thrive in Britain's climate, especially with just a little winter protection or clever site selection.
Tropical-inspired gardens are:
Understanding the British Climate: What You Need to Know
Before delving into plant selection, it's crucial to understand the challenges of growing tropical plants in the UK. Britain's maritime climate features mild temperatures, high humidity, and moderate rainfall. Frost, cold winds, and rainy winters are the main obstacles to consider.
- USDA Hardiness Zones: Most of the UK falls into zones 7-9, with milder areas in coastal or southern regions.
- Microclimates: Urban gardens, sheltered courtyards, and areas near south-facing walls can be several degrees warmer and more suitable for tender plants.
- Winter Wet: British winters are often as wet as they are cold. Good drainage and protection from waterlogging are essential.
Choosing the right tropical plants for a British garden means selecting species and cultivars that combine dramatic looks with reliable hardiness.
Best Hardy Tropical Plants for Britain
Let's look at tropical-looking plants proven to succeed in British conditions. While not all are true "tropicals," they'll certainly bring that coveted jungle vibe to your borders, patios, or container displays.
Architectural Foliage: Palms, Bananas & Ferns
- Trachycarpus fortunei (Chusan Palm)
This palm is the hardiest available in Britain, surviving temperatures as low as -15?C. Its fan-shaped leaves instantly evoke the tropics, and mature specimens become natural focal points. - Musa basjoo (Hardy Banana)
While it rarely fruits in the UK, this banana's vast, paddle-shaped leaves create a lush, exotic effect. Overwinter its roots with heavy mulching, and it will regrow quickly each summer. - Dicksonia antarctica (Tree fern)
This prehistoric beauty prefers a shady, sheltered spot with plenty of moisture. It forms a dramatic, shaggy trunk and distinctive umbrella-like fronds.
Bold-leaved Perennials
- Ligularia dentata ("The Rocket") -- Large leaves further enlivened by dramatic yellow flower spikes. Thrives in moist, semi-shaded spots.
- Fatsia japonica ("Japanese Aralia") -- Glossy, palmate leaves bring vigour year-round; highly tolerant of shade, wind, and pollution.
- Hedychium ("Ginger Lily") -- Grown for its bamboo-like leaves and strongly scented orange or yellow blooms in late summer; best in a sheltered spot.
Colorful Flowering Tropicals
- Canna indica -- Showy, iris-like foliage and brightly colored flowers from midsummer; likes rich, moist soil and full sun.
- Crocosmia -- Arching stems of bright red or orange blooms in late summer; fully hardy and excellent for adding tropical feel.
- Kniphofia ("Red Hot Poker") -- Dense, spiky flowerheads in fiery shades are a magnet for pollinators and add strong vertical lines.
Evergreen Foliage for Year-round Impact
- Cordyline australis (Cabbage Palm) -- Sword-shaped leaves and a tall trunk like a genuine palm; tolerates exposed positions.
- Phormium (New Zealand Flax) -- Strappy leaves, sometimes striped or colored, excellent in coastal gardens or containers.
- Yucca filamentosa -- Tough, spiky, and drought-resistant, its tall flower spikes are dramatic in summer.
Choosing the right tropical plants for a British garden means combining these bold leaved, evergreen, and colorful flowering plants creatively for the ultimate exotic effect.
How to Create a Tropical Feel in the UK: Design Tips
To successfully pull off a tropical garden look in the UK, bold plants need to be matched with smart placement and creative hard landscaping. Here's how:
- Layering: Plant in tiers, with tall "canopy" species (like bananas and palms), medium sub-canopy plants (ferns, cannas), and lush groundcover (hostas, ferns, heucheras).
- Shelter: Site tender plants near house walls, fences, or hedges to break cold winds, trap heat, and provide frost protection.
- Water Features: Ponds, small streams, or even grouped water bowls create humid air and reflect foliage for a jungly look.
- Juxtapose Foliage: Mix different leaf shapes and textures--broad with narrow, glossy with matte, deeply dissected with spiky.
- Bright Accents: Use bold colored plant pots, garden ornaments, or outdoor cushions to enhance the tropical atmosphere.
Remember, a tropical garden is as much about atmosphere and contrast as it is about species selection.
Winter Care for Tropical Plants in a British Garden
Winter is the biggest challenge for tropical style gardens in Britain. The key to success lies in preparation and protection:
- Mulching: In autumn, mulch the base of bananas, cannas, cannas, and tender gingers with thick layers of straw, dry leaves or bark chips to insulate roots against frost.
- Wrapping: Wrap trunks of tree ferns and palms with hessian, fleece, or bubble wrap--but allow air circulation to prevent rot.
- Containers: Grow the most tender plants (Cordyline, palms, brugmansia) in large pots that can be moved into a porch, greenhouse or conservatory during harsh weather.
- Drainage: Ensure all tropicals are in free-draining soil. Damp, cold roots are more dangerous than cold air alone!
- Microclimates: Make the most of sunny courtyards, south-facing walls, or city microclimates to overwinter marginal plants in place with little intervention.
With these techniques, your chosen exotic plants will flourish for years, creating a truly tropical look in your English garden.
Exotic Plant Combinations: Sample Tropical Border for the UK
Here's an example of how you might combine the best tropical plants for British gardens to form a lush, harmonious border:
- Back layer: Trachycarpus fortunei (palm), Musa basjoo (banana)
- Mid-layer: Fatsia japonica (aralia), Cannas, Hedychium (ginger lily)
- Front of border: Ligularia, crocosmia, heucheras, hostas
- Underplant/groundcover: Ferns (Dryopteris, Polystichum), hardy impatiens, Eucomis
- Feature plant or pot: Phormium or colorful bromeliad in glazed pot
Mix in dramatic summer-flowering bulbs and annuals, such as dahlias, zinnias, or coleus, to add extra color and variety.
Popular "Tropical" Plants for Different British Conditions
- For Dry, Sunny Borders:
Yucca recurvifolia, Agave americana (in well-drained pots), palms, echiums, hardy aloe. - For Damp, Shady Areas:
Dicksonia antarctica (tree fern), hostas, Gunnera manicata, Rodgersia, astilbe. - For Exposed Coastal Gardens:
Cordyline australis, phormiums, glauca-leaved palms, sea holly, Erigeron karvinskianus. - For Pots and Conservatories:
Brugmansia, Alocasia, Canna 'Durban', Ensete ventricosum 'Maurelii' (red-leaved banana).
Native Plants with a Tropical Look
Don't underestimate the power of certain British native plants in creating an exotic effect. For example:
- Ferns: Polypody, shield ferns, and hart's tongue look convincingly "tropical"
- Foxgloves (Digitalis): Tall spires mix well with lush foliage
- Meadowsweet (Filipendula ulmaria): Frothy flowers in boggy spots
- Hostas: Lush and extravagant leaves for moist shade
Blending native and exotic species ensures a garden that's both environmentally friendly and beautiful.
Practical Tips for Sourcing and Planting Exotic Plants
- Buy from reputable UK nurseries and garden centers--choose suppliers who specialize in hardy exotics and can offer expert advice.
- Plant in spring or early summer so new introductions can establish strong roots before their first winter.
- Prepare soil with lots of organic matter to improve drainage and fertility, vital for most tropical-style plants.
- Check plant labels for hardiness ratings. Select reliably hardy species unless you're prepared for winter protection.
- Mulch annually with compost, bark, or leaf mould to nourish roots and hold moisture during hot spells.
Troubleshooting: Common Problems with Tropical Plants in the UK
- Frost Damage: Yellowing, limp leaves, or mushy stems after cold nights. Solution: Mulch, wrap, or lift and overwinter indoors if necessary.
- Slugs and Snails: Hostas, cannas and tender shoots are especially at risk. Solution: Use nematodes, copper tape, or mulch with sharp grit.
- Wind Burn: Brown, split, or tattered leaves on bananas, cannas, and palms. Solution: Plant in sheltered spots or provide wind breaks.
- Root Rot: Waterlogged soil leads to wilting or collapse. Solution: Improve drainage by adding grit/sand and planting higher.
