Margaret Armstrong, a prolific book cover designer and illustrator, spent a few years traveling around the western United States at the beginning of the twentieth century, and in 1911 she was one of the first women to descend to the floor of the Grand Canyon. There she discovered some new flower species and began writing and illustrating the exquisite and thorough Field Book of Western Wildflowers.
This was the first comprehensive handbook to supply detailed information about the plethora of flowers growing in the western United States and includes detailed information on seventy-five plant families, like water-plantain, lily, buttercup, poppy, mustard, hydrangea, plum, rose, cactus, wintergreen, figwort, and valerian families, and many others.
Armstrong includes information on key characteristics of each species, including height, leaf and petal features, colors, where each flower can most likely be found, ideal conditions they flourish in, and much more.
