As of the mid-2000s I knew these small white flowers could be found on a few of the margins on the campus of Alfred University in Alfred, New York, where they were largely overlooked by both students and maintenance.

My neighbor has this all around her porch, at least I think it's the same plant. The blossoms don't have any pink in them. Also the seeds are round and the leaves are heart shaped. If it's not Small flowered White Morning Glory, then hopefully someone will tell me what it is.
And I have a LOT of seeds.

This plant grows wild in my area, kinda cute flowers but very small. If you grew it in a garden I would reccomend it as a groundcover rather than a vine as it tends to sprawl rather than climb. Notable features are the green throat and pink anthers.
