The garden borders at Cottesbrooke Hall are made up of pale pinks, deep purples and icy blues. They are the work of garden designer, Arne Maynard who weaves atmosphere into all his planting with an expert eye for detail, use of texture and concept of space. Here he gives his advice on creating a border and lists some of the plants that make up the stunning borders, grouping them together in colour palettes.

How the border was put together

A confident elegance was needed for the border at Cottesbrook Hall. Arne used a pale slice of the colour wheel at the point of pinks, purples and icy blues, given depth by dark aubergine undertones. It’s restrained without being self-consciously monotone. If it had been too rich it would have shouted ‘look at me’ when it needed to complement the bigger picture of the statue walk. Too pale and it would have fizzled away, much too shy for its setting. The palette of plants began with dark plums and rich pinks, un undercoat that brings vivacity to the paler colours that dominate. Planning a border is a little like organising a meal – ingredients are combined to create dishes that deliver a fulfilling feast. Instead of flavours, it’s colours and textures that are being mixed together but it’s useful to think of the need for spice to enhance the taste, or milk and yoghurt to diminish the fire.

The heart of this planting a Cottesbrook Hall is soft and sweet, dominated in June by Digitalis purpurea ‘Sutton’s Apricot’ weaving its pinky-apricot way through the long expanse of the border. It’s shade is matched by Rosa The Generous Gardener (=’Ausdrawn’) trained on dome-shaped frames, which has the presence to divide up the space. Whites and cool blues bring the right amount of luminosity even on a gloomy day.

What to consider before planting a garden border

  • Identifying the mood of your border is the starting point of a plan. Borders can be dark and dramatic, or airy and light, rich and bold, sweet or tart, sometimes brooding and energetic, uplifting or peaceful.
  • Bear in mind that it is more than just the colour combinations that create the look. The shape of the leaves or petals, the number of different plants, the repetition of the same varieties; even personal and historic associations that plants have can affect the overall atmosphere of the border.
  • An infinite number of possible plant combinations exist, but every border has growing conditions that narrow the choice and a setting that is specific to its site.
