Project context

A landscape shaped by its purpose.

The RHS selected landscape architect and garden designer Sarah Eberle as its Iconic Horticultural Hero for the 2022 Hampton Court Palace Garden Festival, recognising a 40-year contribution to horticulture.

Her feature garden was conceived as a journey through world landscapes. Rare and wild plants, many sustainably grown in the UK, moved from a temperate rainforest and woodland edge into arid and meadow conditions.

The brief

What the project had to achieve.

Define a walk-through route across a garden that moved between woodland, temperate rainforest, arid and meadow planting while keeping the material language understated.

  1. 01

    Changing landscapes

    One continuous visitor route needed to connect several distinct planting environments.

  2. 02

    Flexible path lines

    The edge had to respond to curves, corners and transitions throughout the walk-through garden.

  3. 03

    Visual restraint

    Hard-landscape details needed to support the planting rather than become a competing feature.

  4. 04

    Show-build precision

    Interfaces had to be installed accurately within the compressed programme of an RHS show build.

The CORE solution

Selected around the site—not just the surface.

Flexible CORE EDGE was formed around the garden’s changing path and planting lines, creating clear boundaries without competing with the rare and unusual planting.

CORE EDGE was shaped to the designed path and planting geometry, holding the route line as it moved through the garden’s contrasting zones.

The slim steel profile created a clear transition between the gravel path, soil and planting while remaining visually recessive within the finished landscape.

The edge supported a garden built around sustainable and recycled materials, rare plants and a strong message about environmental stress and the importance of nature.

Installation

How the system was installed.

  1. 01

    Show-garden route and planting geometry set out

  2. 02

    CORE EDGE formed to the designed lines

  3. 03

    Gravel path and planting completed to the adjoining levels

The result

The completed feature garden led visitors through a sequence of contrasting landscapes with crisp, controlled interfaces between the route and planting.

Project outcomes

  • Controlled route edges through contrasting planting zones
  • Clear transitions between gravel path and planted ground
  • Flexible steel edging formed to the garden geometry
  • An understated detail within a planting-rich feature garden
