Graham Rice's book contains an invaluable series of plant lists such as plants for different habitats, for different flowering times, for different flower colours, for differents kinds of foliage, for scent, etc.,etc. Furthermore, if you buy a plant and look for it in the index, you will usually find it and thence discover where to plant it and information about its uses. As an experienced gardener and compulsive purchaser of plants, I use it constantly. I have just given my copy to my daughter to help her to plan and plant up her large new garden and, in seeking to buy a replacement, greatly regret to discover that it is no longer readily available.
