Oh wow I have a question . I heard they grow and spread and look like sunflowers ? And what does the patch look like over winter? Do they all die and fall over or you have to cut them down ? Or what ?I would have given away sunchokes! We just dug up. About 50 lbs of them to clear a bed for asparagus crowns. I planted those 2 or 3 years back. We ate some but not very much. They are soft/mushy when cooked. I didn't mind them much, but ultimately didn't think they were much to rave about and like potatoes better. They are tasty and crunchy raw, but we didn't need to keep a bed of them for the occasional desire to eat some - I'll just by some water chestnuts when I wan't to crisp crunch.
