I have four small Jasmine grown from cuttings but they are just from last year so no great progress yet - this is Jasmine Officianalis which is a winter flowering variety - fully hardy and small leaf, all I can say so far is they have been no trouble, I have just been pinching out new growth to develop ramification. The smallest one has started to flower, sorry no pics available, try a Google search, I have seen photos of some mature specimens which look pretty good
