This unique reference work presents the first comprehensive taxonomy of Coryphantha, with a complete key to the genus. It contains a new taxonomic classification of all 43 species and 11 subspecies, with morphological and ecological descriptions. These cacti, which grow in Mexico and southern USA, are characterized by their typical grooved tubercles and large flowers. The book is the result of many years of viewing the literature and fieldwork by the author team and their ongoing commitment to map out the nomenclature of this genus. During this process, the authors even discovered some new plants. More than 300 high-quality colour photos showing the various cacti and their habitats as well as distribution cards and illustrations explaining the morphological details complement the text. Written in an easy-to-follow style and with a chapter on cultivation conditions, the work will not only be an invaluable reference manual for taxonomists and horticulturalists but also for hobbyists and plant collectors.
Since 1987, more than 225 species have been identified and described as endangered, imperiled, or declining. Complete with photographs, line drawings, and county maps, this book describes the officially listed, candidate, and species-of-concern plants in Texas. Individual accounts include information on distribution, habitat, physical description, flowering time, federal and state status, similar species, and published references.
There are many reasons to grow cacti and other succulents—they're drought-tolerant, low-maintenance, and they look great. But what about hardiness? For those who thought that these spectacular plants were only for gardens in California and the Southwest, guess again—hundreds are fully cold-hardy and can be grown outdoors from New England to British Columbia, Wisconsin to Texas. Cacti and Succulents for Cold Climates is filled with inspirational portraits of 274 plants that can be used to create drought-tolerant gardens, as well as tips from regional experts who have mastered the art of growing cacti in parts of the country not usually associated with high temperatures or a scarcity of water. Expert Leo Chance describes how to prepare planting beds, how to get plants well established, how to handle cacti during planting, how to protect plants from cold winters, and when and how much to water.
