Many, many thanks, Tony, for the present of the plants when I called to collect the 2 remaining troughs (one for me and one for Diane). I'll try not to kill them over the winter and might try to plant your trough with NZ plants - might be quite appropriate don't you think. I wish you and your family all the very best of luck for your new life and will keep my eye out for your posts on the Forum.
