I wonder who christened it?

Spotted en passant; while wandering the "estate" in search of a shot.
As near as I can tell it's a Hoary Willowherb
 "hoary
ˈhɔːri/
adjective

1.
greyish white."

HUH?!? Doesn't look grey to me, shiny leaves & pink flowers.
It just caught my eye and I wonder if I could manage something resembling a macro. 
It would appear to have a herbal use or two, must have an investigate.
