Lesley,
I figured it was probably originally from you, given you know Don and Otto and that you liked it so much!! <grin> Mine is growing well at the moment, although now finished flowering. Had it's last flowers a couple of weeks ago (well I am assuming they're it's last flowers for the season!). So as well as my initial Thank You to Otto, there is also one to yourself as well, for introducing it here in the first place!! Thanks everyone involved!!
