Are you struggling to create a thriving garden that balances beauty and sustainability? In this article, you’ll learn how the “right plant right place” principle can transform your landscape into a flourishing and low-maintenance haven.
We’ll break this age-old fundamental piece of advice into two parts: site parameters (restrictions) and plant functions (desirable characteristics). By carefully selecting plants that are well-suited to their environments, gardeners and designers can craft spaces that are both beautiful and functional.
Not many plants can survive in wet feet. In fact, almost all Westringia spp. would die in this wet area, but Grey Box™ Westringia ‘WES04’ PVR has been bred to handle periodic flooding and root rot diseases. https://ozbreed.co.nz/plant-ranges/shrubs-and-ground-covers/grey-box-westringia/
Why Does “Right Plant Right Place” Matter?
Right plant right place is a cliche for a reason. Many a landscape designer have tried putting full-sun loving plants into shade, or free-draining soil-loving plants into heavy clay. The results are that plants die, or they never really reach their full potential.
You’re much better ripping the wrong plant from a space, and replacing it with something that’s better able to tolerate the conditions. Every plant should have access to everything it needs in the garden, so that it can look as good as possible and perform as you’d intended.
Understanding Site Parameters
Site parameters are the foundational conditions that influence plant selection in landscape design. These include climate, soil type, sunlight availability, and water drainage. For instance, plants chosen for a coastal garden must endure salty winds and sandy soils, whereas those placed in a shaded area should thrive without direct sunlight.
Here are a few common site parameters to get you thinking:
- Available space
- Temperature
- Frost
- Wind
- Altitude
- Humidity
- Topography
- Substrate
- Mulch
- Average rainfall
- Drought
- Irrigation
- Sunlight
- Salt
- Micro climate
- Aspect
- Slope gradient
- Reflected light
- Reflected heat
- Rockeries
- Pathways
- Wind corridors
- Depressed areas
- Raised areas
- Flat areas
- Common pests/diseases
This site has serious reflective heat with all of the pebbles and stones, but Tasred™ Dianella tasmanica ‘TR20’ PVR handles it with ease. This plant can also be used in heavy shade, so it’s a real winner. https://ozbreed.co.nz/plant-ranges/strappy-leaf-plants/tasred-dianella/
Understanding Plant Functions
Plant functions refer to the desirable characteristics that plants contribute to a landscape. This includes their growth habits, which define how they fill and shape a space, as well as their role in supporting biodiversity. Plants may provide nectar for pollinators or offer vibrant foliage and seasonal blooms that add visual interest. Understanding these functions allows designers to select plants that meet both practical needs and aesthetic goals.
Here are a few common desirable plant functions:
- Biodiversity resources
- Playgrounds (non-bee attracting, non-poisonous, non-spiky)
- Rockeries (cascading, etc.)
- Grey water
- Fire retardant
- Growth habit
- Erosion control
- Rain gardens and bioswales (wet feet and drought)
- Water cleaning
- Sensory
- Low maintenance
- Order and creativity
- Layering
- Repetition
- Unity
- Rhythm
- Contrast
- Balance
- Colour
- Form
- Texture
- Line
- Proportion
- Focal points
- Seasonal interest
- Mass planting
- Specimen planting
- Feature
- Sightline preservation
- Screening & privacy
- Wind break
- Hedging
- Borders
- Roadside planting
- Parkland
- Street tree
- Modern garden style
- Traditional garden style
- Native garden style
Blurring the Lines Between Parameters and Functions
Interestingly, the distinction between site parameters and plant functions can sometimes become blurred. For example, a “low maintenance budget” might be a parameter due to cost constraints but also functions as a criterion for selecting hardy, low-maintenance plants. Similarly, a “native plant palette” is a parameter that aligns with regional flora but also functions to bolster local ecosystems and biodiversity.
Use this framework to help select plants, but don’t get caught up in useless definitions when they no longer serve a purpose.
Sometimes, you want some border definition but you don’t want to prune it every few weeks. Better John™ Callistemon viminalis ‘LJ1’ PVR only needs pruning once every 2-4 years, depending on how neat and tidy you’d like it to be.
Applying the Right Plant, Right Place Principle
Embracing the “right plant right place” principle in landscape design involves a delicate balance between understanding site-specific constraints and leveraging plant characteristics. By doing so, designers can create landscapes that are not only visually appealing but also ecologically sustainable. This approach ensures that plants thrive with minimal intervention, reducing maintenance efforts and promoting a harmonious relationship between the garden and its natural environment.
Conclusion: The Benefits of Right Plant, Right Place
The benefits of applying the “right plant right place” principle are manifold. It leads to gardens that require less maintenance, conserve resources, and support local wildlife. Moreover, these well-planned landscapes enhance the beauty and functionality of any outdoor space, creating an inviting sanctuary for people and nature alike. By prioritising this principle, gardeners and landscape designers can make informed choices that result in enduring and sustainable garden designs.
