"The book explores how postwar US presidents used communication strategies to craft new roles or personas for presidential leadership that amplified the necessity of American power and inserted American leadership into precarious situations that ensured national engagement in the next conflict"--

Sometimes, to move forward, we must look back. Gardening activity during American involvement in World War I (1917-1919) is vital to understanding current work in agriculture and food systems. The origins of the American Victory Gardens of World War II lie in the Liberty Garden program during World War I. This book examines the National War Garden Commission, the United States School Garden Army, and the Woman's Land Army (which some women used to press for suffrage). The urgency of wartime mobilization enabled proponents to promote food production as a vital national security issue. The connection between the nation's food readiness and national security resonated within the U.S., struggling to unite urban and rural interests, grappling with the challenges presented by millions of immigrants, and considering the country's global role. The same message--that food production is vital to national security--can resonate today. These World War I programs resulted in a national gardening ethos that transformed the American food system.

As the first botanical history of World War II, Plants Go to War examines military history from the perspective of plant science. From victory gardens to drugs, timber, rubber, and fibers, plants supplied materials with key roles in victory. Vegetables provided the wartime diet both in North America and Europe, where vitamin-rich carrots, cabbages, and potatoes nourished millions. Chicle and cacao provided the chewing gum and chocolate bars in military rations. In England and Germany, herbs replaced pharmaceutical drugs; feverbark was in demand to treat malaria, and penicillin culture used a growth medium made from corn. Rubber was needed for gas masks and barrage balloons, while cotton and hemp provided clothing, canvas, and rope. Timber was used to manufacture Mosquito bombers, and wood gasification and coal replaced petroleum in European vehicles. Lebensraum, the Nazi desire for agricultural land, drove Germans eastward; troops weaponized conifers with shell bursts that caused splintering. Ironically, the Nazis condemned non-native plants, but adopted useful Asian soybeans and Mediterranean herbs. Jungle warfare and camouflage required botanical knowledge, and survival manuals detailed edible plants on Pacific islands. Botanical gardens relocated valuable specimens to safe areas, and while remote locations provided opportunities for field botany, Trees surviving in Hiroshima and Nagasaki live as a symbol of rebirth after vast destruction.
