Clematis have long enjoyed popularity in gardens large enough to accommodate them. Now, with the arrival of a new generation of cultivars that excel in mixed borders, containers, and other small spaces, there is more reason than ever to grow them. As well as being modest in height, many of these new clematis are extremely floriferous and self-supporting in a wide range of garden situations and they are joined here by a selection of classic species and cultivars that perform well.

The clematis featured in this book are hand-picked for their longer flowering periods, large flowers and resistance to diseases. Internationally renowned clematis breeder Raymond Evison recommends the best clematis for particular situations, such as containers, mixed borders, patios, deck gardens, hanging baskets, and balconies. Clematis associate well with a variety of other plants and the author lists suitable companion plants and explains how to achieve a compatible mix of color, shape, and other characteristics.

This unprecedented book celebrates a new generation of clematis and will appeak to both established enthusiasts and beginners.
