Rooibos tea is from the plant Aspalathus linearis, maybe you should do a few enquiries under that name, but as far as I can tell it is not grown away from its native lands and sets very few seed. Do you have the Aussie Plant Finder? A new edition came out this year, I do not have it get but it is very useful.
