Jerusalem artichokes are tubers, such as potatoes, but they have a completely different taste and much less popular than potatoes.
Despite the fact that they are called “artichokes” they are not associated with Chinese artichokes (which are also the knobbly tubers) or globe artichoke (which are essentially edible flowers).
Jerusalem artichoke is a part of the family of sunflowers, and some say that the common name (Jerusalem) is derived from the Italian word girasole – meaning “turn to the sun”. The plant has a lot of yellow, daisy-like flowers, and the tuber is no different from the potato, except it is actually very knobbly.
Leaves of the plant are large – anything from 150 mm to 200 mm (6 to 8 inches), and the plant will grow to a height of 1.8 m to 2.1 m (over 60 feet).
