Climbing plants give height and structure to a garden and make a spectacular feature in their own right, such as Wisteria (image top left). Many climbing plants are vigorous which means although they are easy to grow, it is important to check the eventual size of the plant against the space available.
This group plants come in all shapes and sizes, perennial, annual, evergreen and deciduous. The smaller climbing plants, such as compact clematis, and annual sweet peas look just great in the border climbing up an obelisk. A natural way of planting into a border is to allow the climber to scramble using adjacent plants for support and is a popular way of growing Clematis letting it scramble and wind its way around a border.
Since many climbing plants are vigorous they are also ruthless in grabbing, scaling around, clinging , flattening and basically growing over anything in their way. If you let the plant grow through a border, as opposed to tied into an obelisk or a structure, you may need to check its growth as there is a tendency to swamp everything around. It can stunt the growth of plants around by clinging and sometimes pulling more fragile plants down.
