jasmine
Jasmine or star jasmine? Maybe I got a bad batch, but mine took forever to get going (well 4yrs) and only the two in very sunny spots. The other two are still basically nonexistent
The established one I was gifted has been good from the off.
Almost 6rs on the front, East facing, is doing the best. But flower production is absolutely pitiful.
As I said could have been the plant as well as stuff like soil type, feed, etc.
Either way, I stand by my point of getting a one from a decent place.
I'm guessing you want decent coverage? In which case things like Clematis or Passionflower while providing beautiful flowers probably won't give you the foliage you want.
I agree with Brommers on the rose. Find something you like from David Austin https://www.davidaustinroses.co.uk/
Cheap roses are a false economy. Call them for advice if you need more help. Also roses keep their leaves until quite late and start them again early.
You could also try something like a Star Jasmine as it's evergreen. But it will probably need a different planter, and if you do definitely buy an established one from a decent nursery.
