Undeservedly out of print for decades, American Plants for American Gardens was one of the first popular books to promote the use of plant ecology and native plants in gardening and landscaping. Emphasizing the strong links between ecology and aesthetics, nature and design, the book demonstrates the basic, practical application of ecological principles to the selection of plant groups or "associations" that are inherently suited to a particular climate, soil, topography, and lighting. Specifically, American Plants for American Gardens focuses on the vegetation concentrated in the northeastern United States, but which extends from the Atlantic Ocean west to the Alleghenies and south to Georgia.

The plant community settings featured include the open field, hillside, wood and grove, streamside, ravine, pond, bog, and seaside. Plant lists and accompanying texts provide valuable information for the design and management of a wide range of project types: residential properties, school grounds, corporate office sites, roadways, and parks.

In his introduction, Darrel G. Morrison locates American Plants for American Gardens among a handful of influential early books advocating the protection and use of native plants—a major area of interest today among serious gardeners, landscape architects, nursery managers, and students of ecology, botany, and landscape design. Included is an appendix of plant name changes that have occurred since the book's original publication in 1929.

Ahead of their time in many ways, Edith A. Roberts and Elsa Rehmann can now speak to new generations of ecologically conscious Americans.
