Thank you for the synonym--it's not mentioned in the RHS index. My original plant, the one which died, was given to me by Caroline, grown from a cutting from her large one which grew in the ground in her old garden outside Athens. She subsequently moved it to a pot for her town house, where it's ok but not doing as well. I assumed a protected semi-shady corner of the garden would suit it, and it seemed to be doing well till it suddenly died (during a perticularly wet autumn).... I think I'll keep this one in a pot.
