Q.How best to eliminate chameleon plant infestation?
It is rampant and smells revolting when pulled
One reason it is difficult to control is that it spreads from underground rhizomes and can root from broken stems and pieces of plants that fall to the ground. This database recommends manually removing the plants and as many of the roots and rhizomes as possible and disposing of them by incinerating them. They suggest that this will have to be repeated several times to completely get rid of the plants. In other words, you will need to be vigilant to completely eradicate this pest! This is the least harmful method to your land for eradicating this pest. Another possibility is chemical treatment although it appears that this plant is somewhat resistant to herbicides.
