I thought it would be fun to plant some Sunchokes (Jerusalem Artichokes) in an unused corner of my yard, as they don't need to be replanted from year to year.

I was going to order some, but I noticed the local supermarket has them in the produce section. Anyone know if they could be viable for planting? I'm willing to risk a less than 100% chance of success, but if the chances are zero I won't bother.
