It gets sun all day except for early morning (at 7) and late afternoon (at 6). The wall is facing north, so it doesn't have much shadow. I'm planning on planting them next to each other so I'll have something that looks like a flowery privacy screen. I have a bougainvillea in another section of the wall, and the plant next to it enjoys shade from 3 pm to sunset, when the shadows are longer. So maybe some of the roses would be shaded if I planted them close together. The sun's path may be a little different in the winter. I could attach a trellis so the plants won't be touching the wall.
