There is a plant growing beneath our wine. What kind of plant is it? Flower or weed? Five little leafs are on the white blossoms. It is growing very fast. Leaves are large and heart shaped.
Whether you consider it a flower or a weed is up to you - beauty is in the eye of the beholder. I have it amongst other annuals in my wildflower / insect food border and it self-seeds well. Note that most polygonaceae tend to proliferate (and hence are typically seen as weed), so you might want to cut it before it goes to seed. But it's quite controllable by ripping out seedlings, unlike thistles etc.
