She also wrote and illustrated the first comprehensive guide to wildflowers of the American west, Field Book of Western Wild Flowers (1915).

She began her career as a book cover designer in the late 1880s, initially doing commissions for Charles Scribner's Sons and A.C. McClurg and later for other publishers as well.

[2][3] Her later work was influenced by Art Nouveau and favored plant-related motifs, bold colors, gold stamping, and often slightly asymmetrical designs in compositions that often seemed to be moving while standing still.

[1][2] Authors for whom she designed several covers include Frances Hodgson Burnett, Florence L. Barclay, George Washington Cable, Charles Dickens, Paul Laurence Dunbar, Robert Louis Stevenson, Henry van Dyke, and Myrtle Reed.

[2] She has been called "the most productive and accomplished American book designer of the 1890s and early 1900s", and her work is sometimes compared to that of her contemporary Alice Cordelia Morse.
