Hello, this is my first question on this site so hope I get a response! I am a novice gardener so any help would be appreciated. We live in Andalucia and have recently erected an arch and wondered what would be the most suitable (and fast growing) trailing plants to cover it. One will be planted in the ground and the other side plant will be in a pot, it is a north facing wall, shaded in the morning, sun in the afternoon. I have tried growing trailers in pots before without much success. Thanks
