A tropical garden succeeds when it feels intentional. Without a clear theme, even the best plants look confused. In the UK, where climate already limits choices, a theme becomes a filter—guiding what you plant, how you build, and what you leave out.
A theme is not about strict geography. It is about:
- Mood
- Structure
- Foliage type
- Density
- Colour and texture
You can grow bananas in a Japanese garden or palms in an African one—but how they are used must be consistent.
1. South American Jungle
Lush, immersive, dramatic
This is the classic UK tropical look and one of the easiest to achieve if shelter and soil are good.
Defining Features
- Huge leaves
- Dense, overlapping planting
- Fast summer growth
- High humidity feel
Visual Language
- Little bare ground
- Plants touching and leaning
- Height layered from ground to canopy
Structural Approach
- Enclosed spaces
- Curving paths
- Pergolas, trellis, fences hidden by foliage
Best Suited To
- Sheltered gardens
- Gardeners happy with feeding and watering
- Those who want maximum impact in summer
2. Hawaiian / Pacific Tropical
Relaxed, open, architectural
Often confused with jungle planting, this style is actually cleaner and more spaced.

- Resort-style atmosphere
Visual Language

Structural Approach

Best Suited To

3. Tiki / Polynesian Style
Playful, theatrical, immersive
This is a designed fantasy rather than a botanical one, and it works best when fully committed.

Visual Language

Caution
This style fails when:

It requires confidence and restraint to avoid kitsch.

9. Mixing Themes – How to Do It Without Ruining the Garden
Mixing themes is risky but possible.
Rules:
- Choose one dominant theme
- Use others as accents only
- Keep materials consistent
- Avoid mixing dense jungle with minimalist styles
A garden cannot be:
- Jungle
- Japanese
- Desert
all at once.
10. Choosing Your Theme Wisely
Ask yourself:
- How much sun and shelter do I have?
- Do I enjoy dense planting or open space?
- How much winter work will I tolerate?
- Do I want drama or calm?
Your theme should:
- Match your site
- Match your temperament
- Look convincing even in winter
Final Thought
A tropical garden is not made by plants alone.
It is made by decisions, and the first decision is what kind of place you are trying to create.
Once the theme is chosen, every plant either belongs—or it doesn’t.
