To add interest to your garden, you may want to consider having an arch or a pergola. It is a way of adding vertical lines to your garden design and can be a good way of separating one part of the garden off from another section of the garden, especially if your outside space is long and narrow. A pergola also creates shade and may be the perfect position for a bench or, if it is a long pergola or arch, it may be used to cover a path or walkway.
Climbing plants like clematis, climbing roses, passionflowers and wisteria are perfect for growing over an arch or a pergola. You may need to give all of these plants a helping hand from time to time to make sure that they grow exactly where you want them to grow and it is a good idea to loosely tie stems to the frame of your pergola. Wisteria can grow and cover a large area and has strong woody stems. It can become very heavy and you may need to make sure your pergola is sturdy and fit for purpose if you have wisteria climbing over your arch or pergola.
Once, climbing plants are well established, then you will have a garden feature which will be enjoyed for a long time.
