Sunchokes, also called Jerusalem artichokes, are tubers that come from the plant that looks like the picture on the left. They are often mistakenly destroyed as a weed when it is actually edible and quite tasty. They are ready to harvest right before they bloom. They have a slightly nutty flavor and you can use them in recipes that call for jicama, water chestnuts and almonds. They are very easy to grow and, if you live in North America, you might have actually seen them growing in your backyard or in and around your garden.

Harvesting Jerusalem Artichokes

Growing Sunchokes

Sunchokes do well in fertile loamy soil or the kind of soil found in dried riverbeds. About any soil that potatoes and corn do well in will also work for the sunchoke. These tubers do very well in climates similar to North Carolina, where farmers have reported yields of 5 to 7 tons per acre. They prosper in temperatures of 65 to 80 degrees Fahrenheit and less than 50 inches of rain a year. They should be planted in early spring after the last frost. You can plant whole tubers or pieces of tubers that are no less than 2 ounces in size and have 2 or 3 buds. The tubers should not be allowed to dry out before planting. They can be harvested just after the first frost before they have had a chance to become too sugary. A modified potato harvester works well, or you can mow the tops of the sunchokes and then use a hand rake to locate the tubers. Sunchokes are a perennial plant, so if you miss any tubers you can count on them coming back next year. To avoid bruising and damage to the skin, they should be handled carefully and stored in bins in a high-humidity, low-temperature environment.
