Indulge your Passion for Perennials!
Herbaceous perennials are the most popular single group of garden plants. The book is the most comprehensive single volume on perennials ever published, featuring more than 5,000 different plants spread across almost 100 plant families, 450 genera and 2,000 species and accompanied by hundreds of colour pictures. But it's more than just an illustrated A-Z of plant descriptions. Included in many of the plant entries is information about planting associations, propagation ideas, historical insights as well as specific pest or disease problems, which all add value to the coverage.
