This member of the daisy family is ornamental enough for a flower bed and the tuberous roots can be eaten in much the same way as potatoes.
Sow tubers or seeds directly in the position they are to grow.
- Jerusalem artichokes are not recommended for sub arctic areas Seeds can be sown in spring in all warmer climates Suckers can be sown:
- Mid spring in areas with cold winters, snow cover will insulate them but they made need protection from frosts
- Mid winter - mid spring in areas with cool winters, they may need protection from frost however
- Mid autumn - early spring in temperate areas
- Midsummer - early autumn in warm arid, subtropical and tropical areas
Tubers are generally ready to harvest between 20 and 28 weeks after the tubers or suckers are planted. If growing them from seed, you may want to leave them undisturbed for three to four years in order to get bigger tubers and have enough to save for replanting.
Artichokes are used the same way that potatoes are.
Jerusalem artichokes are very high in inulin (a type of fibre) which can improve digestion and encourage good bacteria into your digestive system. Inulin is a fructan however, so some people (those with fructose malabsorption for example) may not be able to process it properly. Jerusalem artichokes also contain lots of potassium and a good amount of iron, copper, phosphorus, thiamine and other B vitamins.
