I don't think that's quite it - the leaf is subtly but significantly different - , but I want to thank you for the response. Peter
It sure looks like Tetrapanax, even the way the leaf lobes double split. Are the leaves very soft and sort of fuzzy, with a lot of fuzz on the stems? On the other hand, the ones I've seen all have flower heads now.
I agree with Daniel... Tetrapanax papyrifer http://www.bbc.co.uk/gardening/plants/plant_finder/plant_pages/11888.shtml
Everyone - thank you very much for your help! What a great resource this forum is - thanks to all the dedicated and kind users. Peter
