At Umber Garden Design, we believe that the best gardens emerge from genuine collaboration between designer and client. Understanding the terminology is a small but meaningful part of that.

Whether you’re embarking on a full garden transformation or commissioning a planting scheme for the first time, knowing the language used in professional garden design helps you ask better questions, make more confident decisions and arrive at a result that truly feels like yours.

This guide covers the key terms you’re likely to encounter when working with a professional garden designer. We’ve organised it to follow the journey of a typical garden project, from the first site visit through to planting and long-term care. There’s also a quick-reference glossary at the end for short, sweet definitions.

The design process: from site to concept

Every garden project begins with close observation. A professional garden designer will spend time understanding the place before proposing any solutions for it.

Site and site analysis

The site simply refers to the plot of land being designed. Site analysis is the process of studying it. So, mapping its boundaries, levels, soil type, drainage, sun exposure, wind direction and existing features. Good site analysis underpins every decision that follows.

Site survey

A site survey is a formal, measured record of the garden. That includes its dimensions, levels, the position of trees and structures, and the location of drains, manholes and service runs. It provides the accurate base plan that all subsequent design drawings are built upon.

Orientation

Orientation describes the direction in which the garden faces relative to the sun. South-facing gardens get lots of direct sunlight, while north-facing ones may be largely in shade. This shapes decisions about seating areas and which plants will thrive.

Microclimate

A microclimate is the localised set of conditions that prevail in a specific area of the garden. Think warmer vs cooler or more sheltered vs more exposed than the surrounding land:

South-facing walls create warm microclimates ideal for tender plants
A dip in ground level can collect frost
A gap between buildings may funnel wind

Concept plan

A concept plan is an early, exploratory drawing that captures the key ideas for the garden without committing to precise dimensions or details. It might show the broad footprint of a terrace, the rough location of planting areas or a proposed circulation route. Its purpose is to test ideas and invite conversation.

Master plan

A master plan is the comprehensive, scaled drawing that shows the complete design for the garden. It includes all hard and soft elements in their correct proportions and positions. For larger gardens or phased projects, the master plan acts as the long-term vision, even if not all elements are delivered at once.

Design objectives

Design objectives are the agreed goals for the project. They might include creating privacy, providing outdoor dining space, improving drainage, making the garden more wildlife-friendly or reducing maintenance.

Rendering and 3D visualisation

A rendering (or 3D visualisation) is a lifelike image of the proposed garden created using specialist software. It allows you to see how the finished space might look before a single sod has been lifted.

Design principles: the foundations of visual thinking

Professional garden designers apply a set of visual and spatial principles that have their roots in fine art, architecture and landscape design.

Balance

Balance refers to elements being distributed in a way that feels stable and considered.

Symmetrical balance places matching elements on either side of a central axis.
Asymmetrical balance achieves the same calm feeling through the careful arrangement of different elements.

Contrast

Contrast is the deliberate use of difference (colour, texture, form or scale) to create visual interest and make individual elements stand out. Without contrast, a garden can feel flat. Too much contrast, and it becomes restless.

Garden focal point

A focal point is a feature that draws the eye and anchors the design. In a well-designed garden, focal points give the eye somewhere to rest and the mind somewhere to go.

Scale

Scale describes the size relationship between elements (plants, structures, furniture and the garden itself). It’s also used technically to describe the ratio of a drawing to the real-world space it represents.

Axis and sightline

An axis is an imaginary line that organises a garden. It usually runs from a significant point in the house (a back door or bay window) towards a focal point or boundary feature. Sightlines are the views along or across these axes.

Garden rooms and garden zoning

Garden rooms are distinct areas within a garden, each with its own purpose, character or planting palette. Garden zoning is the act of dividing a space into these areas, often using changes in level, planting screens, hedging or path alignment.

Enclosure

Enclosure is the sense of containment that gives a garden (or a part of it) a feeling of intimacy and shelter. It can be created by walls, fencing, hedging, planting or a combination of all four.

Softscaping

Softscaping refers collectively to all the living, planted elements of a garden (as opposed to the hard, structural materials). Whilst the term is sometimes used loosely to mean simply 'planting', it more accurately describes the sum of all organic components: trees, shrubs, perennials, bulbs, lawns, groundcover and climbers.

Garden styles: finding a language for your space

Gardens are as varied as the people who make them, but certain broad styles have emerged over centuries of design practice.

Formal design

Formal gardens are defined by geometry, symmetry and strong structural lines, with deep roots in European garden history. Clipped hedges, straight paths, paired plantings and clearly ordered spaces are characteristic.

Informal design

Informal gardens favour curves, asymmetry and a sense of relaxed naturalism. Paths meander, planting spills generously and edges are soft rather than crisp. Crucially, informal design doesn’t mean undesigned.

Contemporary and modernist garden design

Contemporary (or modernist) garden design is characterised by clean lines, bold structural forms and a restrained palette. It tends to draw on architecture, creating a strong visual connection between house and garden.

Naturalistic design

Naturalistic planting and design takes cues from meadows, woodland edges and prairie grasslands. Naturalistic designers work with drifts, layered planting and self-seeding to gardens that mimic the wild.

Cottage garden

The cottage garden is one of Britain's most beloved and enduring styles. An abundant, seemingly artless combination of flowers, herbs, climbers and edibles. Its appeal lies in the sense of overflowing generosity.

Sustainable garden

A sustainable garden is designed to tread lightly on the environment by:

Using water wisely
Supporting wildlife
Choosing materials responsibly
Reducing the need for chemicals or excessive maintenance.

Other styles worth knowing

Beyond the styles above, you may also encounter the following terms when exploring garden design ideas:

Mediterranean garden – Warm, drought-tolerant planting in gravels and terracotta. Suited to sunny, sheltered sites.
Woodland garden – Shade-tolerant planting beneath a canopy of trees. Ferns, hostas and spring bulbs.
Wildlife garden – Designed primarily to support birds, insects and other wildlife through habitat and food sources.
Prairie-style planting – Inspired by North American grasslands. Characterised by ornamental grasses interwoven with late-flowering perennials.

Hard landscaping: structure, materials and build

Hard landscaping refers to the non-living, structural elements of a garden: paths, patios, walls, steps, decking and the groundwork that supports them.

Hardscaping

Hardscaping is the collective term for all the hard, structural elements in a garden. Think paving, decking, walls, steps, edging, pergolas and other built features. The quality and character of hardscaping sets the tone for the whole garden.

Paving, pavers and patios

Paving refers broadly to any hard surface laid at ground level, whether it’s stone, porcelain, brick or concrete.
Pavers are the individual units used to create paving.
A patio is a paved area adjacent to the house used for outdoor sitting and dining.

Decking and composite decking

Decking is a raised or ground-level surface made from boards, traditionally of hardwood or treated softwood. Composite decking blends wood fibre and recycled plastic for better durability and reduced maintenance.

Retaining walls, terracing and raised beds

A retaining wall holds back soil or creates a level change in the garden.
Terracing involves creating a series of level platforms on a slope, often using retaining walls.
Raised beds are framed planting areas elevated above the surrounding ground level, typically constructed in timber, stone or steel.

Groundworks and sub-base

Groundworks are all the preparatory earthworks carried out before construction begins. That includes excavation, levelling, drainage installation and the laying of foundation layers.

The sub-base is the compacted aggregate layer (typically MOT Type 1 crushed stone) that sits beneath paving, providing a stable, free-draining foundation.

Edging

Edging defines the boundary between different surfaces or between hard and soft elements. It keeps gravel out of lawns and paving away from planted borders.

Garden structures

Garden structures include all the built elements above ground level, such as pergolas, arbours and even gazebos.

Permeable paving and SuDS

Permeable paving allows rainwater to pass through the surface and into the ground beneath, rather than running off into drains. This approach forms part of a broader strategy known as SuDS (Sustainable Drainage Systems), which manages surface water in a way that mimics natural processes.

Planting: Structure, layers and seasonal life

Planting is where a garden finds its voice. These are the key terms that describe professional planting practice.

Structural planting

Structural planting refers to the plants that provide the garden's permanent framework. Your evergreen hedges, shaped topiary, multi-stemmed trees and large architectural shrubs. These are the elements that give a garden its form in winter, when everything else has died back.

Layer planting

Layer planting describes the practice of using plants at multiple heights to create depth and ecological richness. There’s typically a canopy layer (trees), a sub-canopy or shrub layer, a perennial or herbaceous layer, and a groundcover layer.

Planting schemes

A planting scheme is the planned selection and placement of plants for a specific area. It considers colour, form, texture, season of interest and cultural requirements.

Seasonal interest

Seasonal interest means keeping something worthwhile in your garden across all four seasons. Think spring bulbs, summer flowers, autumn colour and berries, and winter structure and bark.

Palette and plant palette

The plant palette is the chosen set of species used in a scheme. A well-edited palette has coherence with plants that belong together tonally, ecologically and visually.

Key plant types

Understanding the basic categories of plants is helpful when discussing a planting scheme:

Perennials – Plants that live for more than two years, dying back in winter and returning in spring. Hardy perennials are fully frost-tolerant.
Annuals and biennials – Annuals complete their life cycle in one year; biennials take two. Both provide seasonal colour but require more active management.
Shrubs – Woody plants that branch from near the base; the backbone of many planting schemes.
Evergreen vs deciduous – Evergreens retain their leaves year-round and provide winter structure. Deciduous plants shed their leaves, often offering autumn colour before they do.
Bulbs, corms and tubers – Underground storage organs from which seasonal plants emerge; snowdrops, tulips, alliums and dahlias are all examples.
Climbers – Plants that use walls, fences or structures to reach height; invaluable for adding vertical interest and softening hard surfaces.
Ornamental grasses – Prized for their movement, texture and extended season; central to naturalistic and prairie-style planting.
Specimen plant – A plant grown or placed to be admired as an individual, usually for its form, scale or rarity.

Topiary and espalier

Topiary is the art of training and clipping plants into defined shapes like spheres, cones, clouds or spirals. Espalier is a related technique, where you train trees flat against a wall or framework.

Propagation and transplanting

Propagation is the process of creating new plants by seed, cuttings, division or layering.
Transplanting is the act of moving a plant from one location to another.
Additionally, transplant shock is the stress response that can follow, caused by root disturbance.

Sustainability and ecology: designing with nature in mind

Contemporary garden design is increasingly shaped by ecological awareness. In short, gardens can do far more than please the eye.

Biodiversity

Biodiversity in garden design refers to the range of living organisms that a garden can support. A biodiverse garden is structurally varied, rich in native and wildlife-friendly plants, and provides food, shelter and breeding habitat.

Rewilding

In a domestic context, rewilding means deliberately reducing human intervention to allow natural processes to take over.

Pollinator garden and native planting

A pollinator garden is designed specifically to support bees, butterflies and other pollinating insects through a continuous succession of nectar and pollen-rich flowers. Native planting (using plants indigenous to the UK) is an important part of this, as many specialist insects have co-evolved with specific native plant species.

Drainage and water management

Good drainage is one of the most fundamental requirements of a healthy garden. Key drainage terms include:

Soakaway – A pit filled with rubble into which surface water drains.
French drain – A trench filled with gravel through which water is channelled away.
Rain garden – A shallow depression planted with water-tolerant species that captures and filters surface run-off.
Rill – An ornamental water channel used both aesthetically and to direct water flow through a design.

Soil and growing conditions

Understanding your soil is foundational to choosing the right plants. Key terms include:

pH level – A measure of acidity or alkalinity.
Clay soil – Heavy, moisture-retentive and slow to warm.
Loam – The ideal balance of sand, silt and clay.
Compost – Decomposed organic matter used to improve soil structure.
Mulch – A layer of organic or inorganic material applied to the soil surface to suppress weeds, retain moisture and regulate temperature.
Humus – The dark, stable organic matter produced by the decomposition of plant material.

People and roles: who does what in garden design?

The garden design industry uses several professional titles, and it’s worth understanding the distinctions.

Garden designer

A garden designer creates detailed plans and planting schemes for domestic and commercial outdoor spaces. Anyone can use this term in the UK, but reputable designers typically hold qualifications from the Society of Garden Designers (SGD), the Royal Horticultural Society (RHS) or a specialist college.

Landscape architect

A landscape architect is a qualified professional (typically holding a degree and chartered status with the Landscape Institute) who works across a broader range of scales and project types. This title is regulated in the UK.

Landscape designer

Landscape designer is sometimes used interchangeably with garden designer, but can also describe professionals who work across a broader range of project types and scales. The term is not regulated.

Arborist

An arborist is a specialist in the care, management and surgery of trees. Where a garden design project involves significant existing trees, an arborist's report may be required, particularly when planning permission, conservation areas or Tree Preservation Orders are involved.
