I've spoken to the local nurseries - and even the previous landscaper,
who (reportedly) planted the thing - no one has any idea, even with
seeing fresh cuttings...

If you do cuttings, place them in water with a bit of a willow branch while
you are gathering your supplies. A willow branch and some rootone will
practically guarantee a take.

Hmm, good idea... i'll try that tonight, thanks.
