OK so I have a problem. At the back of my garden there is a corner where there is little light. It has been a kind of nature reserve and there are a couple of trees that shade it. We are taking a few m2. The frogs like to hunt in it because it is close to the pond. It is dug over at the moment. But it gets covered in weeds. The cats crap in it and chase the frogs. It does not get much light.
What I want is a shrub to spread over the area that will provide cover for the frogs, stop the unsightly weeds so cover the soil yet be invunerable to being trampled down by the cats (either prickly or dense). It will also need to be able to grow in low light, and would be nice if it could spread quickly.
Any suggestions appreciated.
