I found it! I found it!
A couple posts back I posted a mystery flower I had in my garden that I couldn't find in any of my gardening books. After google-ing "white flowering perennials", I came upon a website that had twenty pages of them (50 to a page). I figured if I couldn't find it among 1000 varieties of white flowers, I was in trouble. And there it was....Gooseneck Loosestrife (Lysimachia Clethroides). And if you look at the flowers, they do look like little goose heads. How cool! I love answered questions.
