I have an arbor at the entrance of my strata building. It has a western exposure so is shaded by the building till mid-day. and then is shaded by a building across the road by late evening in summer. I would say it is full sun to part sun. Currently there are to plants on either side, but I plan on transplanting the Rhodo and removing the evergreen (see photo). So may question is what would be a good choice be for a climbing vine in this location. I would like to get something that is non invasive and easy to control, preferably with multi season interest. Any suggestion.
