Blue And Purple
If you want to make your garden feel bigger, you can use colour theory to increase its sense of scale. Hot colours stand out and jump towards the eye whereas cool colours fade back.
Plant misty, pale blues at the back of your garden and you can create a feeling of distance. Blue is a restful colour, calming and soothing. It is woods full of bluebells and self-seeding forgetme-nots in a woodland border. Among the many annuals there are long-flowering pansies, while candytuft makes a good companion plant in the veg garden. There are stronger blues too, from rich, deep gentians to the electric blue of globe thistles and sea hollies. Purple is also calming. Think of lavender on a summer day full of visiting bees and butterflies, or the striking balls of alliums on their tall stalks. And for a plant that blooms for months on end, Geranium ‘Rozanne’ has saucer-shaped violet-blue flowers with a white centre and makes a per fect plant for a container.
