Jolana,
NW of Dallas? That's really interesting.
If it does well, I may try and split it and try some in ground. I use the truckloads of oak leaves I have here for insulating faucets and things. I stuff potting soil bags full of leaves and then shove those under something to hold them in place. That really works well. Would be easy enough if I could find something to work for a cover that wouldn't blow away. I've considered getting some straw hay bales and making a bale wall and filling the interior with leaves and putting a cover on. The problem would be invasion by mice and rats. That would be a certainty out here in the boonies.
I'd read once about a fellow that was doing something along those lines to protect a coral vine which he'd moved to the Sherman/Denison area from the Austin area. He was overwintering it with a lot of protection, but it wasn't doing as well as when he had it in Austin. My coral vine got killed by the first freeze, so I'm having to start over with some seeds. They have been slow to get going. I'm not sure they will bloom this year. But I know now to get them completely inside before the first freeze.
I suddenly seem to be trying a lot of vine type plants and they are a difficult problem to solve what with needing winter protection and growing in a windy climate. Combining a trellis in a container with a plant that needs the protection just doesn't work very well and they absolutely have to be anchored strongly during the growing season or they will blow over.
