I have an area at the edge of a woodland where I am having difficulty getting anything to grow. The area gets dappled sunlight, especially the late afternoon. The area is mostly covered in wild strawberry and weeds like persicaria. I have tried oenothera (evening primrose), lamb's ear, Lysimachia punctata, English ivy,and ferns without much luck. The area tends to be very dry and there are lots of tree roots.
A neighbor has offered me some variegated aegopodium (bishop's weed). It looks like it might be a good solution, however all the information says it is very aggressive and hard to get rid of if you change your mind. Some sites recommend using a root barrier. It hasn't been that aggressive in her garden, but I can see that you can't plant it in a mixed bed because it intermingles with everything around it.
Should I try it or am I asking for trouble?
