I want to cover a very ugly garage. Concrete all around so no option of a bed. I’ve just planted a couple of small ivy plants in the hope that they will provide a bit of coverage but I want something really beautiful that will go in a pot. Ideally a climbing rose or some kind of clematis (evergreen would be even better). The pot will be in a thoroughfare so can be deep but ideally not too wide. Area gets full sun half the day and is very sheltered. Has anyone had any success with a climber in these conditions? I read that Gertrude Jekyll roses don’t mind containers? Thanks in advance.
