I'm looking for a Zanthoxylum piperitum (Japanese Pepper, or Sansho) plant, ideally in Sydney. I've looked on-line, and there were leads to Diggers, but they do not appear to have any ATM (or at least there wasn't any reply to an email about availability, and none on the website).
I know they are available, as there is mention of it being used for bonsai, as well as for culinary purposes, but can't seem to find a current supplier.
