Artichokes and Soapwrt

Hi
I am after some Jerusalem Artichokes and Soapwort! They are both hard to find! I live in Sefton area North Canterbury! Can anyone please let me know where I can buy them both?

Hi there, I have plenty of Jerusalem Artichokes growing here in South Canterbury. We will be at an event at McLeans Island, near Christchurch Airport the wknd of the 13/14 April, so could bring some up if you can meet me there? Or I could maybe post at your cost, how many tubers do you want?
