Blue wild flowers

I found these flowers far from our garden. I remember that these flowers grew in our area back in the last century. But then these plants became fewer. I don't know what this flower is called. While gardening, we have never planted this plant.
But in our rural life these blue flowers are constantly present. Nature is generous with wild plants in our region.

And this is a video of the summer as it is
