Sunchoke (Jerusalem Artichoke)
vegetable
Perennial sunflower relative — produces sweet, nutty tubers. Grows 6–10 ft tall; plant on the north edge so it doesn't shade other beds. Raised beds keep the spread in check. Harvest after frost for maximum sweetness. Tubers must be fully dug each fall to prevent taking over.
