Obelix, I had problems growing Chinese Lanterns and really persevered; then they tried to take over the County!. it took days of digging, down to nearly 1 metre to get rid of the roots, which filled 3 sacks. That was after about 3 or 4 years of growth I think. Plant Nurseries really should warn about toxic plants and also invasive ones.
Having said that, Japanese Anemones are not invasive where I have put them; poor soil and pretty dry.
