Jerusalem Artichoke (Helianthus tuberosus) is an easy plant to grow. It is a tall plant with tubers are really enjoyed by rabbits. The leaves can be eaten too. Jerusalem artichokes do well in any soil even and can be planted in odd corners of the garden where other plants fail to thrive. Once some tubers are planted, a permanent bed can be created by leaving some tubers in the soil each year. Artichoke tubers are harvested once the plants start to die back in October/November, but they can be also be left in the soil until required.
