We are doing a Biology project and need some help. This plant has a very dark green/purple stem. It has some feather white poofs that are probably left over from where the flower would have been. It also have pointed green leaves. This was taken in West Tennessee in mid October. Any help is appreciated.

Maybe Prunella vulgaris http://plants.usda.gov/java/profile?symbol=PRVU
For future reference, I just google usda + plant and go into the usda plant database and on the left side click on advanced search and select county, bloom colour, family, etc.

As a hint, I agree it's Lamiaceae but it doesn't have the calyx structure of Prunella vulgaris. USDA Plants is a good place to look.

Haven't studied this too closely but suggest Perilla frutescens.

Wouldn't the Perilla leaves be pretty pungent? I've let some of the purple stuff go to seed and it will have some green offspring as well.

I agree with altagardener--it's highly invasive here, and can be purple or green.
