Jerusalem artichoke is a perennial sunflower. In the Winter, it survives as underground rhizomes, the "artichoke". In the Spring, the knobbly rhizomes sprout one or more stems. These can grow to 2 metres by the Autumn and will then proceed to flower. It is worth growing just for the flowers themselves.
