Herbaceous Perennial Plants

This Fourth edition of Allan Armitage’s Herbaceous Perennial Plants: A Treatise on their Identification, Culture and Garden Attributes differs significantly from the third edition (2008)

Dr. Armitage has added dozens of new species and hundreds of new cultivars from breeders throughout the world.  His comments on morphological characteristics of each species are scientifically sound while simple to understand by any reader.  However, the real value of his writing is in his thoughts concerning a plant’s garden worthiness.

Other significant additions have been the detailed discussions of changes in plant nomenclature and in-depth dialogue on the problem of invasive plants.

The new edition provides easy-to-read information for over 500 genera, species and cultivars used in the gardening and landscape trade.  It also includes Dr. Armitage’s interesting and occasionally controversial thoughts on the Internet, pronunciation of plant names, differences in gardening in the South and North, along with many other topics of interest.

The book is written for professionals and gardeners in the United States and Canada but people throughout the world have also found it useful.
