Hi scoobydoo
You can do lots of things, I have a garden which is surrounded by walls and high fences, and have planted clematis along them to soften them, they look great in Spring and Summer, covered in flowers and leaves, and then I just cut them back in Autumn, and they just spring up again the following year, so easy, you do need to feed and water them, but it's well worth it, I also have some pots of flowers and shrubs, it's a very relaxing place when the sun shines, which hopefully it will soon!!
