hello iv read pretty much all the treads I can find on this plant. and havnt heard about anyone growing them in Australia? im in Victoria and am wondering if this would be a successful place for them to grow? we have cool winters just getting afew frost and quite hot try heat summers. I have just recently bought 6 plants. I also heard from one source that they are susceptible to phytophthora. can anyone verify this? Thank you so much!
