Hi Kim. We can probably help depending on the type. I understand some folks call a rather large white tuber HR. We have the type that grows in the ground as a root, extremely hot, dies back in winter and comes away spring. Used for sauces etc. Is this what you want? Paul.

Just thought I'd mention I found horsradish plants at Mitre 10 today in Westport. I've been looking for it for a very long time so was very happy. Other Mitre 10 store may have it now.
