Thanks Oron. I feel a bit of a fool now as I had just ordered seeds of this plant and didn't recognise the plant when I saw it in the flesh! Happy I did order it now as the flower colour is very strong even in the bright summer light of Rome. I soaked the seeds I had received from a supplier (Jungle Seeds) as instructed but nicking them in addition and put them into sand/compost mix a couple of days ago. 2 had germinated by the following day and 8 by this morning.
I now have the seeds I collected which may be redundant. If so, I will send them to the MGS seed exchange and hope that Chantal will find good homes for some of them.
Thanks again :-)
