This book is a pioneering work on one of the least understood aspects of ecology―the curious phenomenon by which particular plants thrive in the presence of certain species and do poorly in the company of others. The observation of these relationships stimulates imagination and sensitiveness of observation to other living relationships and thereby opens new doors to further understanding of the world of nature. Every gardener and farmer could benefit from having Companion Plants as a reference guide.

This publication represents the work done by Richard Gregg, who used the garden of Evelyn Speiden to conduct certain experiments. A pamphlet resulted, which was published by the Biodynamic Farming and Gardening Association. This book, originally published in 1966, includes that material. It also includes the work of the late Dr. Ehrenfried Pfeiffer, one of the pioneers of biodynamic agriculture, in the fields of sensitive crystallization and chromatography.
