I have them growing wild- everywhere, I have no idea of the variety but the yields are incredibly high. I have never done anything with them and they are now incorporated with the landscaping, they look lovely over arches and such.
If you do not have any, I would also be willing for cuttings, seeing if they root for you- I have Perlite etc on hand, some have just started trailing, some are just with shoots appearing, I am not too sure why or if they can grow from a rootball? I am sure that they could, I can dig one up for you and you can give it a try.
Pm me if this is of any use?!
