Each time I need information about a perennial, I find this book has a listing for that plant. I can't say that about any other perennial reference book that I have used.

Anyone who loves perennial plants should own at least one perennial plant encyclopedia. I highly recommend this 'Encyclopedia of Perennials' by Christopher Woods. This book does not concentrate on pictures, although there are enough photographs to give you an idea of what at least one plant species in each genus looks like.

The listing for each plant genus includes information about cultivation, landscape use, and propagation. After each genus listing, the book offers a wealth of information about the many plant species within each genus of plants. Information for each species includes the common name, the plant's origin, height and spread, description, and zone hardiness. Many cultivars (cultivated varieties of a species of plant) are also listed and described.

As an example, after the general information about Penstemon, seven species are listed and described. One of the species entries reads:
"P. digitalis. Eastern United States. Height 3 ft; spread 2 ft (90 x 60 cm). An erect, clump-forming plant native to open meadows, with elliptic to broadly lance-shaped basal leaves becoming narrower and smaller up on the flower stem. Spikes of bell-shaped, white flowers sometimes flushed pink are produced in early summer. This is a variable species. 'Husker Red' has purple-red leaves, red stems, and white-flushed purple flowers and is a highly desirable cultivar. In general, this species and its cultivar are far easier to grow in hot and humid climates than their western relatives. Zones 3 - 9."

I enjoy the author's style. Christopher Woods provides no-nonsense descriptions, such as his warning about the Houttuynia: "An effective but sometimes ugly groundcover for wet sites, where it can become almost impossible to eradicate. Be warned!"

I have found 'Encyclopedia of Perennials' to be an excellent source of information. More than once, it has prevented me from purchasing a plant with which I would not be happy, and it has also encouraged me to seek out plants that otherwise, I would have passed by!
