Have you tried grocery shops and Asian markets in Chinatown? They often sell plants, either bare-rooted or in pots. You could also check herbalists there as sometimes they sell plants.

I walked extensively through China town today. I managed to find some leaves in Paddys markets but she couldn't tell me where to find a plant. I asked at another place that was selling pot plants, and whilst she was sure there are places around Sydney that grow them, she couldn't tell me where either.

Alot of walking later I ended up at the Newtown Conservatory where the guy insisted they can't grow them in Sydney because the cold kills them.

Total mystery. Anyway, I got some leaves and my search for a plant continues.

Send me a message through "My Page" and I'll give you a few links. I don't want to disturb the official and non-official Gardenweb cops...
