Ordinary Hedera helix but do be sure you really want it growing up your wall. It does cause damage, despite what some people may say, and provides a very convenient ladder on house walls for mice and other small animals (and spiders, and ants...I could go on and on!). It destroys dry-stone walls and ruins fences. It will grow out of the pot and take over the entire garden. Have I said enough?
