Sawyer, who provided inspiration for this book since its earliest stages. John passed away in the summer of 2012, but his contributions to native plants and beyond will last forever. My sweet wife Allison Poklemba has provided much of the love for feeding my passion for plants. Corey Lewis, David Rains Wallace, and David Fix worked with me extensively on the narrative. David Charlet, Stephen Arno, Christopher Earle, and Jeff Bisbee were exceptionally helpful with reviewing range maps and treatments. Denise Newman did one heck of a job copy editing. This book would not have achieved these finishing notes without the folks mentioned, and many others. While the successes of the book are due to all reviewers listed below, any shortcomings are solely attributable to the author. Content was thoroughly reviewed as well, but understandings change and new ideas arise. Inevitably, there will be issues to address in the next edition. Contributing reviewers, in alphabetical order: All photos by author, unless Stephen Arno otherwise noted.
