In 2019, the Indiana Dunes National Lakeshore received a facelift from Congress and became the sixty-first na­tional park, Indiana Dunes National Park. This unique region at the southern tip of Lake Michigan gives rise to one of the most biologically diverse parks in the Na­tional Park system, yet, unlike many of our national parks, a basic field guide for wildflowers has not previ­ously been compiled. With approximately 1,600 taxa of vascular plants in the roughly 15,000 acres of the park, and adoring all plants as we do, it was incredibly difficult to pick out a select group of wildflowers to showcase in this book. Even after weeding out ferns, grasses, sedges, rushes, and most woody species (trees, shrubs, and woody vines), we still spent countless hours determin­ing which taxa to keep and which taxa could be omitted. The selected species were chosen through a combination of their frequency, abundance, charisma, and relation­ship to the trails through the Indiana Dunes National Park. Other than a small self-published book by Dianne Chaddock that highlighted some wildflowers from the dunes region in Indiana and Michigan, no book since Donald Peattie’s 1930 technical Flora of the Indiana Dunes has been published to showcase the incredible floristic diversity specific to the Indiana Dunes. We de­cided that this needed to change. The Indiana Dunes National Park is the seventh-most-visited park in the nation, with more than 3.6 million visitors per year.
