Wild white aster maybe.
I have some blooming, will get a photo tomorrow.
Not sure of the botanical name, but if it has tiny white blooms, then maybe.
I think it also can have light purple tinted blooms.
Mine came from the wild and I let it grow till it bloomed, just to see what it was. It's very tall, taller than I am, and much like garden phlox, but with narrower leaves and of course the blooms are much different.
Yours looks like mine though. I'll check.
Kent might know.
