The general morphology of a Jerusalem artichoke plant can have a critical impact on its productivity. The rapid canopy development and its general architecture are critical attributes in the competitive success of the species in natural settings. The morphology of the plant is genetically regulated, and there are distinct differences among clones. In addition, within a clone there is tremendous plasticity in the final structure. Two genetically identical plants grown under differing conditions develop morphologically into very different plants. In addition, the plant’s structure is not fixed but is constantly changing during the season. New organs are produced while others senesce and are shed from the plant.
