I'm hoping someone out there can help me to identify a plant. Out by the barn, there is this amazing plant growing. It's about six feet tall with pink flowers. We've looked in our plant guides and on the internet, and we think it might be Joe Pye Weed, which I read is a member of the sunflower family named after an Indian who treated colonists with it for typhus. A description says that the leaves smell like vanilla when crushed, and ours do not. What do the gardeners among us say?
