The ones with the purple flowers. The tag I marked it with says Anise...but couldn't find anything in the PDB that looked like it...so is it just a different kind or what??
here's a url for anise ... http://www.ibiblio.org/pfaf/cgi-bin/arr_html?Pimpinella+anisum , go down the page to the web resources to see image.
ur plant looks more like some sort of mint than anise. hth.
Agastache foeniculum Anise Hyssop
