A plant ID, please?
Apologies for the bad quality image, but it's a screencap from a TV series. I know that it's Vervain/Verbena, but I'm trying to narrow it down to a variety. Any suggestions would be appreciated. If it's any help, the plants used will most likely have been sourced from the Altanta, Georgia area. Also, how easily does this stuff spread/grow in the wild, and if you removed all of it from a wild area that would stay a wild area and have no further intervention, would it be likely to stay gone, or creep back in eventually? Thank you for helping with my geekish silliness. ;)
