When you hang the name of a Royal Horticultural Society garden on a new introduction, it had better be good. Clematis Wisley is better than good. It comes from Raymond Evison’s superb breeding program on the Isle of Guernsey. The rich, 5in purple flowers of Wisley appear on new growth, allowing you to use this compelling shade in a series of color combinations throughout the summer.
For beautiful colors, extravagance of blooms, and graceful habit, nothing compares with Clematis, the queen of flowering vines. These plants enrich a landscape whether twining on posts and fences, clambering through shrubs and trees, or following a wire frame in a border. Give them good soil, reasonable moisture, and shade at their roots.
