I've been searching the internet without much luck. I recently purchased land in the Catskills, NY. My husband and I dug a few of these plants up thinking that they may be a wild flower and replanted them at our primary residence. So far they are about two foot tall with no sign of a flower. Any idea of what it may be?

You may find these hard to grow in the new location. Be sure to read up on their cultural requirements.
