 The book, along with "Birds Worth Knowing" (also by Blanchan), and other books such as "Animals Worth Knowing", was part of the "Little Nature Library" series published by Blanchan's husband Frank Nelson Doubleday.It contains over 40 color illustrations accompanying the text, which is arranged by plant family under the classification system of Gray's "New Manual of Botany" as revised by Robinson and Fernald.This is in contrast to Blanchan's earlier work, where the flowers were organized by color.
