Thank you for the comments. I think at best the spot gets 2-3 hours of sun a day. When we have good rains, somehow the water drips heavily in this spot off the gutter. This is where the original house and the addition joins.
I have a picture; it can do better than I at describing the spot.
As you can see, even the weeds are not thick. There is free growing Violets, which I leave alone for the most part, some English Plantain and chickweed. Grass...
I forgot to mention the Clematis virginiana, as you can see it is out a little further. This spot gets more sun.
The soil next to the house is not clay like we have elsewhere, but there are lots of little rocks. I suspect it might have been from earlier landscaping before we moved here. Not much sand to speak of. It seems a nice dark moist soil. There used to be hosta on the north side of the house, but never in this corner.
