Wild Flowers Worth Knowing was published in 1917 (and republished in 1922) as a result of an adaptation by Asa Don Dickinson of Neltje Blanchan's earlier work Nature's Garden (1900). It covers mostly North American species, with a sprinkling of cosmopolitans, and includes a preface by Blanchan (who died in 1918). 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.
