A feeling of distance can also be created by repeating drifts of warms colours followed by cool colours throughout the garden. A splash of vivid colour is always an eye-catching feature in the garden. For example some annuals will only flower for a few weeks, while others, such as Petunias will flower for much longer. Avoid using too many plants which flower all year but never have a heavy crop of flowers. Avoid using too many plants which are used as cut flowers.
Gardens are often bare of flowers because they are always getting picked.
You can get plants with a tremendous variety of leaf colours, from reds and purples, to greys and golds. In autumn, the leaves of deciduous plants change colour before they drop to the ground. Some plants seem to change colour from one part of the day to another as the sun is reflected from the leaves in different ways. Try looking at the difference in foliage colour between afternoon and sunset. Some plants have variations in foliage colour from one time of the year to the next.
