Need something tough in full shade
If you see the shovel in the picture, this is where I would like a narrow, vertical, upright evergreen. The area is narrow, with the shovel about 3 feet from the foundation. It is sloped away from the foundation. The soil is compacted subsoil mildly acidic clay. It gets no sun as it is against a north wall and blocked by trees to the west. It is also in an area where snow sometimes slides off the metal roof.
I know I will need something tough. The rest of the area will be ferns and other tough herbaceous perennials, so I really would like something upright. This is the area I see from the kitchen window! We are in the NC mountains. Rather wet winters.
