@ Gina - Thanks for the advice, but dormancy is the problem for us. We tend to visit late Aug - mid Sept, when the bush is still very much actively growing. So the ?'n is whether cuttings taken around this time will be viable. Guess it might still be worth a try just to find out, and the potential reward giving us all the incentive we need.
@ greg - looks like you've got an offer from Harvey you can't afford to refuse. Job done.
@ gorgi - whilst cursing the wretched peel, just think of all those powerful antioxidants coursing through your cardio-vascular system.
