This plant came up in my Eastern Tennessee yard from any area that had previously been filled with gravel. The plant has grown to about 6 ft tall now with very wispy (like fennel) type leaves or needles. When crushed it has a very herbal scent like something that you would use in the kitchen. There is a second one growing about 20 ft away in an area where we have some pots and rocks. Any help would be appreciated.
