10 Sunchokes are also called Jerusalem Artichokes. Why? Strangely even I have no answer. Sunchoke plants for sale are not anything like an Artichoke. Sunchokes will grow about 6 to 7 feet tall. And in just about any kind of soil that drains well. Here's an important tip for you.
Don't harvest till late fall. Let all the leaves turn brown and dried up before trying to harvest the Sunchokes from the soil. They need all the nutrients in the leaves to finish off growing the tubers.
