I've had half of my main garden area overtaken by what I think to be Florida betony or Stachys floridana. Everything I've seen on the web is very similar but not exactly the same. The root nodules on "mine" are not compressed together like rattlesnake rattles but rounder and the roots, or tubers, get rather long. Maybe to five or six inches. Also, the blooms seem larger on the web photos. I'm wondering if anyone knows of another similar plant that might grow wild in south western Georgia. I'm thinking of eating the invasive rascals but since I'm seeing slight differences, I'm looking for more information. I know photos would be a big help but that will have to wait until I can take some. Thanks for any info!
