I got MILK WEED from my mother in law. I loved the smell of the flowers. The shape and hight was beautiful for around my little pond where I needed something medium height and dense and something that could soak up a lot of ground water. What a mistake. When I learned it was invasive, I pulled it out right away in the same season I planted it and for 2 years now it has been coming back in spots that are several meters away from the original location. As soon as I see one coming up I pull it out. The roots are deep. I am hoping that all the pulling will eventually exhaust the roots. I made a mistake by not reading up on the plant before I planted it. I usually do but this one was unexpected since it always looked so clean and well kept in the other garden. I had no idea how fast it spreads. I am having real issues with horsetail equisetum. No plant will compete with this one in terms of aggravation and amount of work keeping it in check. Getting rid of it? I think that will never happen. I will try to torch it next.
