1) "I have a feeling that dee2000 was looking for the answer to a quiz "for people that know everything" that erroneously states that "Of all vegetables, only two can live to produce on their own for several growing seasons. All other vegetables must be replanted every year. What are the only two perennial vegetables?". If you get the email quiz with the answers, it states that they are asparagus and rhubarb. Guess the quiz-masters didn’t know everything, huh?"

Ranging beyond the usual suspects (asparagus, rhubarb, and artichoke) to include such “minor” crops as ground cherry and ramps (both have found their way onto exclusive restaurant menus) and the much sought-after, antioxidant-rich wolfberry (also known as goji berries), Toensmeier explains how to raise, tend, harvest, and cook with plants that yield great crops and satisfaction. Perennial vegetables are perfect as part of an edible landscape plan or permaculture garden. Profiling more than a hundred species, with dozens of color photographs and illustrations, and filled with valuable growing tips, recipes, and resources, Perennial Vegetables is a groundbreaking and ground-healing book that will open the eyes of gardeners everywhere to the exciting world of edible perennials."
