Perennials 

Newly revised, this third edition of Heritage Perennials' 'Perennial Gardening Guide' provides concise descriptions of over 1,000 varieties of perennials, hardy ferns, ornamental grasses and herbs. This edition greatly expands the second, by adding hundreds of new photographs and recently introduced perennials and grasses. Published by one of North America's leading growers and producers of perennials, the book is an authoritative, yet easy to read and enjoy, guide to perennials and other herbaceous garden plants. The book provides a basic introduction to perennials, ferns, grasses and herbs, and then goes on to list and describe many of the varieties available to gardeners in North America today. Plants are described as to their best locations, height and spread and bloom time, along with special use attributes. Basic information regarding pests and diseases, as well as winter protection and pruning, etc. is provided where needed. Over 530 full color photographs are included, which simplifies plant selection and identification. Comments from numerous gardeners and professional horticulturists, along with the author's biases and personal observations add interest and a lighter touch to this reference book. An index helps to match Latin to common names, as well as cross referencing older and newer Latin names. - from Amzon
