Helianthus tuberosus

sunchoke, Jerusalem artichoke

Sunchoke is enjoying a resurgence of popularity due to its potato-like tubers, which grow quickly and make a great potato alternative. This aggressive sunflower is best planted in a large container, as any fragment of tuber can sprout a whole new plant!
