Hallson Gardens

I have never seen this before. Was at a nursery, and their plants were on sale, seen this and it is really pretty. But didn't get it because I know nothing about them! The leaves are heart shaped, remindes me of a morning glory.
Any info on this plant? I may have to go back and get it LOL!

I took a wildlife class and this vine was recommended.
There is a butterfly that favors this vine.

It has a lot of foliage compared to blooms and it makes a good quick screen. It is supposed to reseed a lot. I have been looking for a start but have never found it around here.
