One thing we avid gardeners learn is how mixing colors in the garden can make a dramatic impact on the viewer.

By themselves these Clematis would have been half as impressive.

When you use vines in the garden you can entwine vines with different colors that bloom at the same time or entwine vines that bloom at different times. So when the one stops blooming the other one takes over. Any way you do it vines are a vital part of any garden and I make use of them whenever I can.
