This is a nice book; I liked it but I didn't love it. As the title states, it is a field guide, but not so in the traditional sense. It is filled with poetry, essays, and prose pieces, some letters, each having to do with an American wildflower aka a flowering native plant. A huge and diverse variety of authors is included, contemporary and historical, with watercolor painting accompaniment. The paintings are quite different than I had expected. They are meant to imply pressed flowers that you might want to save in a poetry book but are detail free. Each one is loosely drawn with hard edges, then filled with flowing paint, wet paint on wet paper. They do look flat. Without the labels, one would find it hard to identify the sample. They are the opposite of botanical painting. Now, this is not a criticism, just an observation.
I did not read every selection, but I read at least three quarters of them, the ones that interested me. There are names I know, and more that I don't. I must admit that I found an outsized number of the poems to be on the sorrowful side, but I did love George Washington Carver's contribution during WWII about the many types of weeds that are edible, in case the US population ran out of green vegetables. He included tantalizing cooking and serving tips!
The most interesting part of this large volume, for me, was the author Susan Barba's introduction where she explains the conception of and evolution of her book. Her heart is very much in it.
