Something we enjoy a lot with beef, beetroot etc. So, I acquired a

The question is; is it a rampageous spreader I would regret letting
loose in the garden, or should it be held captive (perhaps in a large
buried pot)?

It is invasive and vigorous. I would be inclined to grow it in a largish
isolated surrounded by concrete raised bed. The old walled garden ~2
acres not far from me was full of the stuff. It took them about three
years to dig it out to the point where it didn't return.

But like docks it's not really invasive if it's not allowed to seed itself.
