Part of the allure of perennial gardening is the fact that a gardener can plant something once and enjoy it for several years, a benefit that has rarely been extended to vegetable gardeners. Save for such stalwarts as asparagus and rhubarb, most edible crops can be used only annually. Thanks to Toensmeier, gardeners need no longer be frustrated by such limitations. From air potatoes to water celery, Turkish rocket to Malabar gourd, there are more than 100 new species of edible plants. After addressing such cultural basics as site selection and preparation, Toensmeier explains why each plant is an excellent perennial vegetable crop. Now that such items are making their way onto trendy restaurant menus and health-store shelves, Toensmeier's groundbreaking guide is destined to become the bible for this new class of edible gardening.
