Be very careful when planting horseradish as it is invasive, confine it to a container.

Hi Keith, Like you, I am also keen to get some horse radish plants as the stuff you can buy here is only the creamed sort and a bit bland. Did you have any luck finding a source?

Search for some seed selling companies on the internet in NZ.
