Growing Jerusalem Artichoke is VERY easy and is grown as a perennial with tubers. MAKE SURE YOU PICK A SPOT IN YOUR GARDEN OR YARD where they can get a bit out of control. They will spread if you're not careful about managing them.

Stems are heavy, and grow 3 to 12 ft in height. The plant produces yellow flower heads in late August and September.

Jerusalem Artichoke is similar to water chestnuts in taste. The tubers resemble potatoes except the carbohydrates compose about 75 to 80% of the tubers are in the form of inulin not starch.
