Question
Hello, I transpl this years ago from somewhere in MA, but am not positive where. It bloomed today, is 6'6" now meas along the stem and about that every year. I don't let it get too dry. It is hollow-stemmed. I see that Eutrochium fistulosum can be that tall, but I don't see a pale cast to the stem, just a pale fuzziness in the framework of the flowers (sorry, lack terminology). It's not really purple, a little pale violet toward top. Leaf whorls all 5. Spotted-stem pic is 1 foot off ground.
Answer
Dear corylus, identification of Eutrochium can be really difficult, and from images it is sometimes easy and other times almost impossible. The flower heads look to have too few flowers for E. maculatum, suggesting this would be E. dubium or E. fistulosum. That is the best I can do with the images supplied. Best wishes.
