I was out at a nursery with my kid today and they had them for sale.
We laughed at the price, but every one needs to start somewhere.
I recently bought some tubers from Whole Foods, to expand my varieties.
They cost 6 bucks a pound!
They were certified organic and they are a specialty crop, but still...
I have eliminated jchokes from some beds where they previously dominated by repeatedly cutting down the stalks.
I've heard of people forcing/blanching the stalks for human consumption.
Rabbits love the leaves and stalks , fresh or dried.
If you repeatedly harvest your
sunchoke stalks at a foot high and hang them in bundles to dry, you can weaken the patch and at the same time gather "hay" for mulching or animal
feed.
If you invert opaque buckets over the regrowth, you might get a unique edible to sell at farmers markets.
