That is Phlox Minnie Pearl. I had just ended bloom,I cut those back about 1/4th so they will bloom in late summer and fall.
Your acres sound fantastic. What I would give to be 40 years younger and lots of time and money.
My strength is in planning and not so much the deeper characteristics of individual plant. I just don't have that type of brain.
Here is Minnie Pearl
That is Red Husker penstemon behind the phlox which blooms in June.
