I think the cautions regarding cold that I've read are for first year plants only. I don't expect any problems once established. We have maybe six more weeks until the usual time for a killing frost and then on into November (usually) before freezing weather.
The cuttings were given to me so I have no idea about their source but I am guessing they from are the same vines.
I don't mind big and a bit unruly (just a bit) as I have a large expanse of Bermuda grass that I'd like to shade out.
But I'll keep an eye on them once they get growing.
Question: do the leaves of the different varieties look significantly different to tell if the cuttings are from the same plant?
Thanks, I'd love to have some of your cuttings in the Spring.
