Jerusalem Artichoke: The Most Effortless and Delicious Plant of Autumn

Jerusalem artichoke (Helianthus tuberosus) is a perennial tuber plant native to North America. The flowers resemble sunflowers, and the nutty-sweet tubers can be eaten raw, roasted, or pickled. It's one of the most low-maintenance plants in our garden — a true perennial that renews itself each year. High in inulin (a prebiotic fiber), it doesn't raise blood sugar, making it a good alternative to potatoes for diabetics. Harvest from late October through February once the leaves have dropped.
