Hi, I would love to find out where in the Hawkes Bay region I can buy a plant or cutting? Having grown up in Sweden / Europe with many traditional dishes containing the wonderfully hot root (grated and mixed in sauces, potato salads etc. .. the list is long) I truly miss the unique flavour ...

Found this site looking for where to put my horseradish and saw someone wanted echinacea. I have some.

Hi, I would love to plant horseradish in my Waihi garden. Is there anyone in the area who can spare a piece of root? Cheers, Vera

I have plenty of horse radish, but I live in United States and I don’t know if I can send the roots over seas. If I can mail the roots I will. Does anyone know?

New Zealand has strict quarantine laws when it comes to importing fruit, herbs and vegetables.I am sure they would not let it come in.

Would really be grateful if someone in Southland has a piece I could strike a plant from please

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.

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.
