Palms won't grow here and other myths : warm-climate plants for cooler areas
"A professor of botany at a Midwestern university as well as an avid gardener, Francko backs up ideas with empirical research. He debunks myths about the kind of plants that can be grown - even without extensive winter protection - in areas with cool to outright cold winters. Francko delves into the science of cold hardiness, explaining how plants protect themselves in winter and how gardeners can make use of microclimates and simple techniques to add two or more USDA hardiness zones to their garden habitats. Nearly 300 species and varieties of warm-climate and subtropical plants - from citrus trees to needle palms - are described in detail
