160 pp, 74 color photos, 12 line drawings, 7 x 9 1/2", paperback.

Raymond Evison, world authority on clematis, here provides a fresh look at the genus by focusing on not just the popular large-flowered cultivars but also on the less well known species. A comprehensive plant encyclopedia divided into the distinct clematis groups provides detailed and authoritative descriptions of nearly 375 species and varieties.

14 Quick Tips from
The Gardener's Guide to Growing Clematis

  • Always buy clematis plants from a good source. Short, stocky, well-rooted plants are as good as, or better than, poorly established plants in large containers.
  • Check the zone rating before purchase to avoid disappointment.
  • In cold climates, plant in the early spring so that the clematis becomes established before the following winter.
  • In mild, warm climates, plant in the autumn to obtain root establishment before the following year’s hot summer.
  • Select the winter-hardy forms for extremely cold climates.
  • Select the New Zealand or Mediterranean species and their cultivars for hot climates, such as California, along with the more traditional species and cultivars.
  • Always plant the root crown an extra 5-7.5 cm (2-3 in) deeper than the soil level of its container to help root establishment and give extra protection to the root crown during the heat of summer and the winter cold.
  • Protect the plant’s top growth in extremely cold climates.
  • Protect container-grown clematis over winter so that the old wood can be retained to produce the large early flowers.
  • In cold areas do not expect the clematis to reach the heights given in the A-Z of Species & Cultivars, which apply to the British climate. These must be used as a guide only.
  • Plant deep-coloured or white-flowered clematis plants in hot sunny positions.
  • Plant the pale colours in shady positions to avoid the flowers fading prematurely.
  • Make sure the root crown is well protected by plant material or stone slabs in very hot climates to give the required cool root system.
  • Never underestimate the amount of water required for newly planted clematis, or for established plants in periods of dry weather.
