Sunchokes or Helianthus turberosa is a native perennial plant to Tennessee. Interestingly enough, this plant is not a true artichoke nor is it from Jerusalem lol. It is however, a large, robust yellow perennial sunflower with broad, thick leaves and rough, hairy stems. The root or tuber from this plant is highly nutritious and, unlike potatoes, contains no starch, but rather carbohydrate in a form that is metabolized into natural sugar. Be careful, however, because many people experience stomach issues if they consume this tuber, especially in large quantities. Care Sunchokes have low water needs. Water when soil is completely dry as needed. They prefer full sun and average, well draining soil. They even tolerate clay soil more than most. Best grown as a perennial in zones 3-9. Growth Habit Can spread aggressively, so choose a location for them with care! They can also get 6-12ft tall. Typically found along woodland borders and in thickets. They usually bloom late summer through autumn.
