Artichokes Jerusalem (Helianthus tuberosus)
A member of the sunflower family, and the only one in this country cultivated for human food. On account of its rapid growth, the Jerusalem artichoke is frequently used as a screen on the vegetable plot. It will grow in almost anyor position, but it definitely repays good cultivation.
Planting is done in February or March. The tubers are set 6 in. deep in rows, with 2 ft. between each tuber. When the tops have blackened in autumn they are cut back nearly to ground level. The tubers can remain in the ground to be dug for use as required. The best varieties are New White, Old Red, or Purple Skinned.
It is worth noting here that the Jerusalem artichoke is second in food value only to the potato.
