Unfortunately, chameleon or Saururaceae, h. cordata, is an invasive species that is very aggressive and difficult to control. Because this plant spreads from underground rhizomes, you will not be able to control it by pulling or mowing. I have not been able to find any products that specifically list this plant on the label, and there is very little information from US sources on management of this plant. We would recommend trying RoundUp QuikPro, a non-selective herbicide with two active ingredients, or Southern Ag Brush Killer. These are excellent active ingredients that will damage most plants. You would want to give either product 10-14 days to see results. Be sure to give the plants enough time to die completely before tilling or disturbing the soil where they were growing.
