For lazy gardeners such as ourselves nothing beats perennial vegetables. Plant ’em once and you’ve got food for years. For novice gardeners, perennials are plants that, unlike say broccoli (an “annual”), don’t need to be replanted every spring. The best known perennial vegetable in the west is probably asparagus which, given the right conditions, will produce fresh stalks for years. But there are many thousands more perennials little known to North American gardeners that are a lot easier to grow than fussy asparagus.
Unfortunately, there used to be a lack of information about edible perennials until the publication of Eric Toensmeier’s excellent book, Perennial Vegetables: From Artichokes to Zuiki Taro, A Gardener’s Guide to Over 100 Delicious and Easy to Grow Edibles. We’ve got a few of the species Toensmeier mentions: artichoke, prickly pear cactus, stinging nettles, crosnes (more on those in another post) and goji berries. Edible Perennials contains growing information for each species offering something for every climate in North America.
Up to now many of these plants were hard to find, but growing interest in edible perennials and the power of the internet has brought many of these species into our backyards. See the Mother Earth News Seed Search Engine on the right side of this page to hunt down some of the more rare items.
Now, time to fertilize those goji berries and ponder the controversial air potato.
