An Illustrated Encyclopedia of Clematis, Leeds, Everett; Toomey, Mary

This long-awaited book is separated into two sections: the first is devoted to the care and cultivation of clematis, while the second provides an A-Z directory of more than 550 plants, from the acclaimed large-flowered forms to the less-familiar shrubby, subshrubby, and herbaceous forms that are beginning to be available. Using everyday language, the authors provide plant descriptions that include information on synonyms, origin, plant habit and height, flowers, pruning group, flowering period, cultural requirements, recommended uses in the garden, and hardiness zones. The text is accompanied by more than 650 magnificent color photos, making this encyclopedia an indispensable reference and guide.
