Lesley,
I saw pictures of these herbs a good few years ago, I think it was Steve Newell who showed them from borrowed slides. I was so impressed but since then I have not heard much about them. I would love to have a go at growing them but I believe it is not easy to get seed as they are so protected.
I remember the large daisys. I persume these Crems. come from an area that is in the monsoon or that they are subject to a lot of mists.
I think the same reasoning about growing them applies to all plants, out of 2 species growing next to each other in the wild one will take to cultivation and one won't. Some just don't like being tamed
Thanks John for forwarding this thread,Finn is perhaps our best bet.
