This looks like our native obedient plant, Physostegia virginiana:
There are many flowers with very similar foliage. To be certain of the id, let it flower. If it is not obedient plant, send us a photo and should be about to identify with certainty then.

Many good plants spread by roots or rhizomes, and we assume you want to area to fill in with vegetation. If it is a good native, it's just a matter of how much you want to devote to it.
