The Importance of Colour in Gardening

By Reuben Garden

No matter how much careful planning and planting have gone into your garden, it can all be to no avail if the ultimate sizes of the plants have not been considered, and this means the width or spread of the plants, not just their height.

Hot summer days can be cooled down by the white flowers of Philadelph us and the blues of delphiniums. The pinks of camellias in spring hint at the warm days of summer to come, while the bold flame reds, yellows and oranges of the autumn foliage of Acer and Cotinus can furnish us with memories of warm colours to carry us through winter to what seems a far-off spring. Yellow, gold and white plants can be used as focal points to create vistas that add the illusion of space and distance, and these include the winter stems of birch (Betula) or the golden foliage of the cut-leaved elder (Sambucus racemosa `Plumosa Sitwell"). Such plants can also he used brighten up a dull, uninteresting or dark corner by reflecting what little winter light there is available.

Flowers not only offer colour but also scent, and when the two coincide, the effect of each can be heightened. The appreciation of a particular fragrance is always a personal matter, and what gives pleasure to one may not be detected by another. it is worth remembering, too, that some plants, especially roses and lilies, are expected to be fragrant. In fact, this is not always the case, and if scent is important to you, check that the variety you are proposing to plant is, in fact, scented.

In all the entries in the directory there is an indication of the average height and spread that is to be expected from any given plant over a given number of years. However, it is worth bearing in mind that a plant's development will always be influenced by the conditions in which it is grown.

Silver and grey plants, such as santolina (cotton lavender) and artemisias. arc the ideal foil for most other colours, and they can be introduced to create buffer zones between strong colours, such as reds and blues, and to provide somewhere for the eye to rest.

This may seem obvious, but many gardens, even those apparently well designed, do not look exciting or stimulating simply because the number and balance of the plants in them have not been thought through and acted upon.
