Planting Design Principles: How to Use Colour, Texture, and Form to Create Cohesive Garden Borders

Designing a garden border is more than just planting flowers—it’s about crafting a living canvas that balances colour, texture, and form. This guide explores planting design principles to create visually stunning and cohesive borders.

Understanding the Key Design Elements

1. Colour: Setting the Mood

Colour is a powerful tool in garden design, capable of evoking emotions and creating atmosphere. Consider the following:

• Colour Theory Basics:

  • Warm colours (reds, oranges, yellows) bring energy and draw the eye.

  • Cool colours (blues, purples, greens) create a calming and soothing effect.

  • Use complementary colours (e.g., blue and orange) for contrast or analogous colours (e.g., yellow, orange, red) for harmony.

• Seasonal Colour Planning:

  • Choose plants that bloom in succession to maintain interest throughout the year.

  • Incorporate foliage with striking hues, such as the burgundy leaves of Heuchera or the silver tones of Artemisia.

2. Texture: Adding Depth and Interest

Texture refers to the surface quality of plants, from soft and feathery to bold and spiky. A mix of textures ensures your garden is engaging up close and from a distance.

• Fine Texture:

  • Plants like Ferns or Ornamental Grasses add lightness and movement.

• Coarse Texture:

  • Large, bold foliage, such as Hostas or Rhubarb, creates strong visual anchors.

• Balance is Key:

  • Combine fine and coarse textures to avoid monotony and achieve balance.

3. Form: Establishing Structure

Form is the shape and growth habit of plants, from upright and columnar to sprawling and cascading.

• Vertical Forms:

  • Use plants like Italian Cypress or Delphiniums to draw the eye upward.

• Mounding Forms:

  • Rounded shapes, such as Lavender or Geraniums, provide softness and fill gaps.

• Sprawling or Cascading Forms:

  • Trailing plants like Creeping Thyme or Trailing Ivy soften edges and add movement.

Tips for Creating Cohesive Borders

1. Layering for Depth

• Place taller plants at the back, medium-height plants in the middle, and shorter plants at the front.

• For island beds, position taller plants in the center and step down towards the edges.

2. Repetition and Rhythm

• Repeat key plants or colours throughout the border to create rhythm and unity.

• Use odd numbers of plants in clusters for a more natural look.

3. Contrast and Focal Points

• Introduce contrast by pairing fine-textured plants with bold foliage.

• Use a standout plant or garden ornament as a focal point to anchor the design.

4. Incorporate Seasonal Interest

• Include a mix of evergreen plants, deciduous shrubs, and perennials to ensure year-round appeal.

• Don’t forget bulbs for seasonal pops of colour, such as Daffodils in spring or Alliums in summer.

5. Use Hardscaping for Structure

• Edging materials like stone or metal define borders and prevent plants from sprawling.

• Paths and stepping stones can guide the eye and add a sense of purpose.

Plant Suggestions for Stunning Borders

• Tall Structural Plants: Verbascum, Foxtail Lilies (Eremurus)

• Mid-Layer Plants: Phlox, Salvias, Coreopsis

• Ground Covers: Ajuga, Creeping Jenny (Lysimachia)

• Foliage Focus: Hostas, Heucheras, Astilbe
