We've got this growing near berry vines at our farm, and I'm not sure what it is. My Mother-In-Law thought it was an ornamental flower used as filler in floral arrangements. There is an old home near where this is growing, that's got all sorts of hydrangeas and four o'clocks, etc., so I assume it is not a wildflower. Does anyone know what it is? http://www.flickr.com/photos/27520785@N07/sets/72157620595050805/ Any help would be greatly appreciated! Thanks! Heather
