A few warnings about sunchokes or Jerusalem artichokes: they are commonly known by some people as "fartichokes" and they are vigorous growers. First the inulin affects some who eat large quantities thus the name fartichokes. Pickling them with vinegar takes this problem away.
Sunchokes are a vigorous grower and can spread rapidly. A few sunchoke tubers left to overwinter can turn into a large patch in no time. They are also a wonderful livestock food, chickens and pigs both enjoy sunchokes with no fartichoke effects.
