Wall covering, or trailing plant for tall wall
I have a problem with people graffiti-ing on the wall surrouding my garden. I am considering trying to make it more difficult by covering the wall with a plant, but this is more difficult than it sounds.
The grafiti to is the exterior, and I can only plant on the interior of the wall. I could plant something that climbs the wall and trails over, or perhaps put up a wall basket on my side and trail straight over... or maybe you can think of another suggestion?
The wall is approx 2m tall and curves round the garden, so difficult to say about facing. Any ideas?
