Mark Griffiths, Michael Pollock: The Royal Horticultural Society Shorter Dictionary of Gardening

The RHS Shorter Dictionary of Gardening is a comprehensive, quick-reference source to gardening and horticulture. Compiled with keen gardeners and students particularly in mind, it gathers into one volume a treasure trove of information and advice about plants, practical horticulture and cultivation techniques, botanical and gardening terms, pests and diseases and common names.
The A to Z style provides easy access to a huge range of essential information, creating an effective gardening library in one volume and drawing together information that would usually appear in a number of gardening books. The diverse content includes references to little-known aspects of the subject as well as explanations of all the practical details of the gardener's craft. It contains descriptions of over 1900 genera with many more references to species, hybrids and cultivars.
Included throughout the text are colour photographs and specially commissioned line drawings that illustrate gardens, plants and gardening techniques.
