Eutrochium fistulosum (Hollow Joe Pye Weed)
A big one! If happy and in a good site this plant can push 10' tall! If you have room for a big perennial in the garden that is native and loved by pollinators this is a hard one to pass up. If you don't have a few perennials in your garden that you have to look up at to see in flower you are missing out!
