Related to the sunflower, the Jerusalem artichoke is native to the northeastern USA and southeastern Canada. Its tall, hardy plants produce beautiful blossoms and delicious tubers that taste very much like artichoke hearts. A prolific plant, nothing produces more food per square foot than the j-choke. Unlike many wild edible plants and fungi, j-chokes are easily transferred to the garden . . . where they might do so well you may come to regret transplanting them.
