I don't know what it is. I spotted it a few days ago, growing on the side of a hill above a marshy area. It's big, probably about six feet tall. This shot is from about thirty feet away and only shows the very top of the plant.
The hardest part of this shot was keeping still, since my dog was with me. Walks are the high point of her day so she races about like mad, trying to sniff everything imaginable. Which means I'm trying to keep still while a seventeen pound missile on the end of a line careens recklessly around me. I pretty much had to sit on her to get her to stay still for a minute. This is exactly why I don't usually take the dog and the camera out at the same time.
