Perennials will give you spectacular flowering, and since they stay year after year, they are less trouble for people who have less time to garden. Choosing the colours of flowers and textures of leaves is a primary step when you decide to plan your beds. Too much of the same shade could be dull and even irritating to look at. If you have strong colours that predominate in your garden, you can bond them by adding another plant that includes a bit of their colour. For example, if you have a garden mostly in red and dark orange, you could add flowers which contain yellow-orange that will link them all together.
Colours also can set the mood.
You may want to have a warm entrance for your visitors and a relaxing backyard for you and your family. Pink and blue shades produce a peaceful atmosphere, and yellows, reds and oranges are very vigorous and stimulating. Never forget that flowers that have a background of greenery will have more sparkle and vibrance. The foliage provides a bridge between colours . Insert leafy plants, but be aware of coloured foliage that could sometimes clash with the flowers.
