I've bought a beautiful arbour with three sets of trellis and want a plant to grow up it. It needs to be green all year around, ideally have white flowers at some point and not be too dense as I like the light to come through.
It will be in a pot, it's shaded in the morning, but then full sun all afternoon/early evening. I don't really like roses.
Any ideas? I should probably add that I'm pretty good at killing things, so easy to look after would be helpful!
