I would call it a lax climber rather than non-climbing. Mine is growing along a chain link fence and needs little help. Some photos of these I have seen have it growing at the top of a wall and trailing down.

I also have Inspiration, another lax climber, on a trellis. It fills in nicely with only needing a vine tucked in here and there now and then.

Thanks, MN. This is actually very helpful.
