Two horseradish plants were moved to a new bed to mature. They were over-wintered in pots in the ground. The plant is treated as an annual. Any piece of a root will re-grow. Two plants produce a large quantity of horseradish condiment.

Horseradish is an invasive perennial here.
I suspect that if you've left even a scrap of root, it'll reappear where it was.

It grows well here but certainty not invasive. Zone 5
