Flowering tree ID

[MrFancyPlants]

Any idea on ID?
The provenance is that this was a plant was an extra when we got some flowers and sbux gift cards for the teachers at our kids’ schools.
The roots are tuberous but the thing is so vigorous, I can’t help but give it a go. I brought it in before an early freeze.
Edit: grows like a vine.

Looks like mandevilla vine, whitefloweted variety.

Sure does, thank you. I am glad I brought it in before the first frost, but it seemed to be holding up to the “fall” temps better than my ficus and citrus. It is blooming away and hardly a leaf dropped.
