Going back to the posts on Hibiscus trionum, this is a NZ native which my mother used to grow. I have never had much luck with it, I suspect because my soil is too heavy. Charithea, what are the regulations about importing small quantities of seed into Europe from New Zealand? I ask because one of the big NZ seed companies sells packets of seed of "Puarangi", as it's called in Maori. If you'd like some without waiting to get some from the seed bank, I could easily slip a couple of packets into an envelope and post it to you - just send me a message with your address. Hilary, if you google Puarangi stamp you'll see that Hibiscus trionum featured on stamps in the 1960's both before and after we changed over to decimal currency.
