Looks nice! Got any close ups of the flowers.
It reminds me of a Mirabilis but I do not know if any occur in your area but if I can see the flower close up then I may have a good idea as to plant family, such as rose, gentian, or ?? It is a start!

Hello,

My best guess is that it is Silene dioica (also known as Lychnis dioca). Go to the following web site and see if your plant matches:
