Sunchokes have a white flesh that is nutty, sweet, and crunchy, similar to chestnuts when raw. When you bake them in their skins, they become similar to potatoes while having a mild taste like artichoke hearts.
You can eat sunchokes either raw or cooked. However, for some people, they can cause excess gas due to the fact they store energy as inulin.
During the summer, they sport tall, yellow flowers. They can grow to be 6-10 feet tall and 3-5 feet wide. Sunchokes are a great plant to grow for novice gardeners.
