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.

I’ve just acquired some in Southland. I’ll grow it up this season and can pass some root on to you in autumn/winter if you’d like? If you send me your email address, I can let you know when I harvest it.

I bought the Horseradish cuttings from eBay. They were sent from Springvale in Melbourne. Fast and easy and they all took off
