Specialty Gardening: I need a few suggestions, 1 by sempervirens

I would like to add at least 1 tall spectacular plant at the back of this long narrow shade garden. Something that would look wonderful backed by the brick wall. I would love to add a trellis with a vine but I don't think I'd be allowed the trellis.
This is a school garden so spring, fall and winter appearance are important. No one sees it in the summer so I try to pick plants with the other 3 seasons in mind. It also would have to be low maintenance. There is no easy water access so after the plant or shrub is established it would have to hold it's own and not be aggressive.
Any ideas?
