Answer: The ideal would be for you to plant a climber in the soil at the end of the wall and train it along. Plants in containers can become rather stressed, and being trained to a wall, you can't repot them. A good evergreen climber for this spot, whether sunny or shady, would be Pileostegia viburnoides, which has white flowers and leathery leaves. You can use containers for climbers further along the wall, but they may have a limited life unless you can repot them every other year. After having put up wires 30-45cm apart, try Trachelospermum jasminoides, Clematis armandii or Solanum crispum Glasnevin. Use a John Innnes No 3 compost, with extra grit mixed in for better drainage.
