I have lesser celandine here, but it's not been too much of a problem. I like its bright yellow color in the spring. I also have dead nettle, and the trailing variety has caused more problems than the upright one. And jewelweed, well jewelweed is supposed to grow in the vicinity of poison ivy, as it is an antidote. We have poison ivy and we have jewelweed, but it's not much of a problem either.

The plants that were problems were dock and a few I don't know the names of, but have been contending with for years. I don't mind the weeds in the yard, in fact, there are more weeds than grass in my yard. But I don't want them taking over the veg garden like they did last year, with the connivance of the clover cover crop!
